WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime with small footprint, high performance and highly configurable features for applications cross from embedded, IoT, edge to Trusted Execution Environment (TEE), smart contract, cloud native and so on. It includes a few parts as below:
|
||||
- [**VMcore**](./core/iwasm/): A set of runtime libraries for loading and running Wasm modules. It supports several execution modes including interpreter, Ahead-of-Time compilation(AoT) and Just-in-Time compilation (JIT). The WAMR supports two JIT tiers - Fast JIT, LLVM JIT, and dynamic tier-up from Fast JIT to LLVM JIT.
|
||||
- [**iwasm**](./product-mini/): The executable binary built with WAMR VMcore supports WASI and command line interface.
|
||||
- [**wamrc**](./wamr-compiler/): The AOT compiler to compile Wasm file into AOT file
|
||||
- Useful components and tools for building real solutions with WAMR vmcore:
|
||||
- [App-framework](./core/app-framework/README.md): A framework for supporting APIs for the Wasm applications
|
||||
- [App-manager](./core/app-mgr/README.md): a framework for dynamical loading the Wasm module remotely
|
||||
- [WAMR-IDE](./test-tools/wamr-ide): An experimental VSCode extension for developping WebAssembly applications with C/C++
|
||||
|
||||
- The [**"wamrc" AOT compiler**](./README.md#build-wamrc-aot-compiler) to compile WASM file into AOT file for best performance and smaller runtime footprint, which is run by "iwasm" VM Core
|
||||
|

|
||||
|
||||
```shell
|
||||
cd wamr-compiler
|
||||
./build_llvm.sh (or "./build_llvm_xtensa.sh" to support xtensa target)
|
||||
mkdir build && cd build
|
||||
cmake .. (or "cmake .. -DWAMR_BUILD_PLATFORM=darwin" for MacOS)
|
||||
make
|
||||
# wamrc is generated under current directory
|
||||
```
|
||||
|
||||
For **Windows**：
|
||||
```shell
|
||||
cd wamr-compiler
|
||||
python build_llvm.py
|
||||
mkdir build && cd build

Application framework
|
||||
===================================
|
||||
|
||||
By using the iwasm VM core, we are flexible to build different application frameworks for the specific domains, although it would take quite some effort.
|
||||
|
||||
The WAMR has offered a comprehensive framework for programming WASM applications for device and IoT usages. The framework supports running multiple applications, that are based on the event driven programming model. Here are the supporting API sets by the [WAMR application framework library](./doc/wamr_api.md) :
|
||||
|
||||
- Timer, Inter-app communication (request/response and pub/sub), Sensor, Connectivity and data transmission, 2D graphic UI
|
||||
|
||||
Browse the folder [core/app-framework](./core/app-framework) for how to extend the application framework.
|
||||
|
||||
# Remote application management
|
||||
|
||||
The WAMR application manager supports [remote application management](./core/app-mgr) from the host environment or the cloud through any physical communications such as TCP, UPD, UART, BLE, etc. Its modular design makes it able to support application management for different managed runtimes.
|
||||
|
||||
The tool [host_tool](./test-tools/host-tool) communicates to the WAMR app manager for installing/uninstalling the WASM applications on companion chip from the host system. And the [IoT App Store Demo](./test-tools/IoT-APP-Store-Demo/) shows the conception of remotely managing the device applications from the cloud.
|
||||
|
||||
|
||||
WAMR SDK
|
||||
==========
|
||||
|
||||
Usually there are two tasks for integrating the WAMR into a particular project:
|
||||
|
||||
- Select what WAMR components (vmcore, libc, app-mgr, app-framework components) to be integrated, and get the associated source files added into the project building configuration
|
||||
- Generate the APP SDK for developing the WASM apps on the selected libc and framework components
|
||||
|
||||
The **[WAMR SDK](./wamr-sdk)** tools is helpful to finish the two tasks quickly. It supports menu configuration for selecting WAMR components and builds the WAMR to a SDK package that includes **runtime SDK** and **APP SDK**. The runtime SDK is used for building the native application and the APP SDK should be shipped to WASM application developers.
|
||||
|
||||
|
||||
Samples
|
||||
=================
|
||||
|
||||
The WAMR [samples](./samples) integrate the iwasm VM core, application manager and selected application framework components.
|
||||
|
||||
- [**basic**](./samples/basic): Demonstrating how to use runtime exposed API's to call WASM functions, how to register native functions and call them, and how to call WASM function from native function.
|
||||
- **[simple](./samples/simple/README.md)**: The runtime is integrated with most of the WAMR APP libraries, and a few WASM applications are provided for testing the WAMR APP API set. It uses **built-in libc** and executes apps in **interpreter** mode by default.
|
||||
- **[file](./samples/file/README.md)**: Demonstrating the supported file interaction API of WASI. This sample can also demonstrate the SGX IPFS (Intel Protected File System), enabling an enclave to seal and unseal data at rest.
|
||||
- **[littlevgl](./samples/littlevgl/README.md)**: Demonstrating the graphic user interface application usage on WAMR. The whole [LVGL](https://github.com/lvgl/lvgl) 2D user graphic library and the UI application are built into WASM application. It uses **WASI libc** and executes apps in **AOT mode** by default.
|
||||
- **[gui](./samples/gui/README.md)**: Move the [LVGL](https://github.com/lvgl/lvgl) library into the runtime and define a WASM application interface by wrapping the littlevgl API. It uses **WASI libc** and executes apps in **interpreter** mode by default.
|
||||
- **[multi-thread](./samples/multi-thread/)**: Demonstrating how to run wasm application which creates multiple threads to execute wasm functions concurrently, and uses mutex/cond by calling pthread related API's.
|
||||
- **[spawn-thread](./samples/spawn-thread)**: Demonstrating how to execute wasm functions of the same wasm application concurrently, in threads created by host embedder or runtime, but not the wasm application itself.
|
||||
- **[multi-module](./samples/multi-module)**: Demonstrating the [multiple modules as dependencies](./doc/multi_module.md) feature which implements the [load-time dynamic linking](https://webassembly.org/docs/dynamic-linking/).
|
||||
- **[ref-types](./samples/ref-types)**: Demonstrating how to call wasm functions with argument of externref type introduced by [reference types proposal](https://github.com/WebAssembly/reference-types).
|
||||
- **[wasm-c-api](./samples/wasm-c-api/README.md)**: Demonstrating how to run some samples from [wasm-c-api proposal](https://github.com/WebAssembly/wasm-c-api) and showing the supported API's.
|
||||
- **[socket-api](./samples/socket-api/README.md)**: Demonstrating how to run wasm tcp server and tcp client applications, and how they communicate with each other.
|
||||
- **[workload](./samples/workload/README.md)**: Demonstrating how to build and run some complex workloads, e.g. tensorflow-lite, XNNPACK, wasm-av1, meshoptimizer and bwa.
|
||||
- **[sgx-ra](./samples/sgx-ra/README.md)**: Demonstrating how to execute Remote Attestation on SGX with [librats](https://github.com/inclavare-containers/librats), which enables mutual attestation with other runtimes or other entities that support librats to ensure that each is running within the TEE.

Build WAMR vmcore (iwasm)
|
||||
=========================
|
||||
It is recommended to use the [WAMR SDK](../wamr-sdk) tools to build a project that integrates the WAMR. This document introduces how to build the WAMR minimal product which is vmcore only (no app-framework and app-mgr) for multiple platforms.
|
||||
# Build WAMR vmcore
|
||||
|
||||
WAMR vmcore is a set of runtime libraries for loading and running Wasm modules. This document introduces how to build the WAMR vmcore.

|
|||
``` Bash
|
||||
cmake .. -DWAMR_BUILD_INTERP=1 -DWAMR_BUILD_AOT=0 -DWAMR_BUILD_LIBC_WASI=0 -DWAMR_BUILD_TARGET=X86_32
|
||||
```
|
||||
|
||||
## Cross compilation
|
||||
|
||||
If you are building for ARM architecture on a X86 development machine, you can use the `CMAKE_TOOLCHAIN_FILE` to set the toolchain file for cross compling.
|
||||
|
||||
```
|
||||
cmake .. -DCMAKE_TOOLCHAIN_FILE=$TOOL_CHAIN_FILE \
|
||||
-DWAMR_BUILD_PLATFORM=linux \
|
||||
-DWAMR_BUILD_TARGET=ARM
|
||||
```
|
||||
|
||||
Refer to toolchain sample file [`samples/simple/profiles/arm-interp/toolchain.cmake`](../samples/simple/profiles/arm-interp/toolchain.cmake) for how to build mini product for ARM target architecture.
|
||||
|
||||
If you compile for ESP-IDF, make sure to set the right toolchain file for the chip you're using (e.g. `$IDF_PATH/tools/cmake/toolchain-esp32c3.cmake`).
|
||||
Note that all ESP-IDF toolchain files live under `$IDF_PATH/tools/cmake/`.
|
||||
|
||||
Linux
|
||||
-------------------------
|
||||
First of all please install the dependent packages.
|
||||
Run command below in Ubuntu-18.04:
|
||||
|
||||
``` Bash
|
||||
sudo apt install build-essential cmake g++-multilib libgcc-8-dev lib32gcc-8-dev
|
||||
```
|
||||
Or in Ubuntu-16.04:
|
||||
``` Bash
|
||||
sudo apt install build-essential cmake g++-multilib libgcc-5-dev lib32gcc-5-dev
|
||||
```
|
||||
Or in Fedora:
|
||||
``` Bash
|
||||
sudo dnf install glibc-devel.i686
|
||||
```
|
||||
|
||||
After installing dependencies, build the source code:
|
||||
``` Bash
|
||||
cd product-mini/platforms/linux/
|
||||
mkdir build && cd build
|
||||
cmake ..
|
||||
make
|
||||
# iwasm is generated under current directory
|
||||
```
|
||||
|
||||
By default in Linux, the `fast interpreter`, `AOT` and `Libc WASI` are enabled, and JIT is disabled.
|
||||
And the build target is set to X86_64 or X86_32 depending on the platform's bitwidth.
|
||||
|
||||
There are total 6 running modes supported: fast interpreter, classi interpreter, AOT, LLVM JIT, Fast JIT and Multi-tier JIT.
|
||||
|
||||
(1) To run a wasm file with `fast interpreter` mode - build iwasm with default build and then:
|
||||
```Bash
|
||||
iwasm <wasm file>
|
||||
```
|
||||
Or
|
||||
```Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_INTERP=1
|
||||
make
|
||||
```
|
||||
|
||||
(2) To disable `fast interpreter` and enable `classic interpreter` instead:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_FAST_INTERP=0
|
||||
make
|
||||
```
|
||||
|
||||
(3) To run an AOT file, firstly please refer to [Build wamrc AOT compiler](../README.md#build-wamrc-aot-compiler) to build wamrc, and then:
|
||||
```Bash
|
||||
wamrc -o <AOT file> <WASM file>
|
||||
iwasm <AOT file>
|
||||
```
|
||||
|
||||
(4) To enable the `LLVM JIT` mode, firstly we should build the LLVM library:
|
||||
``` Bash
|
||||
cd product-mini/platforms/linux/
|
||||
./build_llvm.sh (The llvm source code is cloned under <wamr_root_dir>/core/deps/llvm and auto built)
|
||||
```
|
||||
|
||||
Then pass argument `-DWAMR_BUILD_JIT=1` to cmake to enable LLVM JIT:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_JIT=1
|
||||
make
|
||||
```
|
||||
|
||||
Note:
|
||||
By default, the LLVM Orc JIT with Lazy compilation is enabled to speedup the lanuching process and reduce
|
||||
the JIT compilation time by creating backend threads to compile the WASM functions parallely, and for the
|
||||
main thread, the functions in the module will not be compiled until they are firstly called and haven't been
|
||||
compiled by the compilation threads.
|
||||
|
||||
If developer wants to disable the Lazy compilation, we can:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_JIT=1 -DWAMR_BUILD_LAZY_JIT=0
|
||||
make
|
||||
```
|
||||
In which all the WASM functions will be previously compiled before main thread starts to run the wasm module.
|
||||
|
||||
(5) To enable the `Fast JIT` mode:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_FAST_JIT=1
|
||||
make
|
||||
```
|
||||
The Fast JIT is a lightweight JIT engine with quick startup, small footprint and good portability, and gains ~50% performance of AOT.
|
||||
|
||||
(6) To enable the `Multi-tier JIT` mode:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_FAST_JTI=1 -DWAMR_BUILD_JIT=1
|
||||
make
|
||||
```
|
||||
The Multi-tier JIT is a two level JIT tier-up engine, which launchs Fast JIT to run the wasm module as soon as possible and creates backend threads to compile the LLVM JIT functions at the same time, and when the LLVM JIT functions are compiled, the runtime will switch the extecution from the Fast JIT jitted code to LLVM JIT jitted code gradually, so as to gain the best performance.

|
||||
```
|
||||
By default in MacOS, the `fast interpreter`, `AOT` and `Libc WASI` are enabled, and JIT is disabled.
|
||||
And the build target is set to X86_64 or X86_32 depending on the platform's bitwidth.
|
||||
|
||||
To run a wasm file with interpreter mode:
|
||||
```Bash
|
||||
iwasm <wasm file>
|
||||
```
|
||||
To run an AOT file, firstly please refer to [Build wamrc AOT compiler](../README.md#build-wamrc-aot-compiler) to build wamrc, and then:
|
||||
```Bash
|
||||
wamrc -o <AOT file> <WASM file>
|
||||
iwasm <AOT file>
|
||||
```
|
||||
Note:
|
||||
For how to build the `JIT` mode and `classic interpreter` mode, please refer to [Build iwasm on Linux](./build_wamr.md#linux).
|
||||
|
||||
WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](./build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in MacOS, interpreter, AOT, and builtin libc are enabled by default.
|
||||
|
||||
Windows
|
||||
-------------------------
|
||||
|
||||
Make sure `MSVC` and `cmake` are installed and available in the command line environment
|
||||
|
||||
Then build the source codes:
|
||||
``` Bash
|
||||
cd product-mini/platforms/windows/
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
cmake --build . --config Release
|
||||
# ./Release/iwasm.exe is generated
|
||||
```
|
||||
|
||||
By default in Windows, the `fast interpreter`, `AOT` and `Libc WASI` are enabled, and JIT is disabled.
|
||||
|
||||
To run a wasm file with interpreter mode:
|
||||
```Bash
|
||||
iwasm.exe <wasm file>
|
||||
```
|
||||
To run an AOT file, firstly please refer to [Build wamrc AOT compiler](../README.md#build-wamrc-aot-compiler) to build wamrc, and then:
|
||||
```Bash
|
||||
wamrc.exe -o <AOT file> <WASM file>
|
||||
iwasm.exe <AOT file>
|
||||
```
|
||||
Note:
|
||||
For how to build the `JIT` mode and `classic interpreter` mode, please refer to [Build iwasm on Linux](./build_wamr.md#linux).
|
||||
|
||||
WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](./build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in Windows, interpreter, AOT, and builtin libc are enabled by default.
|
||||
|
||||
MinGW
|
||||
-------------------------
|
||||
|
||||
First make sure the correct CMake package is installed; the following commands
|
||||
are valid for the MSYS2 build environment:
|
||||
|
||||
```Bash
|
||||
pacman -R cmake
|
||||
pacman -S mingw-w64-x86_64-cmake
|
||||
pacman -S mingw-w64-x86_64-gcc
|
||||
pacman -S make git
|
||||
```
|
||||
|
||||
Then follow the build instructions for Windows above, and add the following
|
||||
arguments for cmake:
|
||||
|
||||
```Bash
|
||||
cmake .. -G"Unix Makefiles" \
|
||||
-DWAMR_DISABLE_HW_BOUND_CHECK=1
|
||||
````
|
||||
|
||||
Note that WASI will be disabled until further work is done towards full MinGW support.
|
||||
|
||||
- Since memory access boundary check with hardware trap feature is disabled, when generating the AOT file with `wamrc`, the `--bounds-checks=1` flag should be added to generate the memory access boundary check instructions to ensure the sandbox security:
|
||||
```bash
|
||||
wamrc --bounds-checks=1 -o <aot_file> <wasm_file>
|
||||
```
|
||||
- Compiler complaining about missing `UnwindInfoAddress` field in `RUNTIME_FUNCTION`
|
||||
struct (winnt.h).
|
||||
|
||||
|
||||
VxWorks
|
||||
-------------------------
|
||||
VxWorks 7 SR0620 release is validated.
|
||||
|
||||
First you need to build a VSB. Make sure *UTILS_UNIX* layer is added in the VSB.
|
||||
After the VSB is built, export the VxWorks toolchain path by:
|
||||
```bash
|
||||
export <vsb_dir_path>/host/vx-compiler/bin:$PATH
|
||||
```
|
||||
Now switch to iwasm source tree to build the source code:
|
||||
```bash
|
||||
cd product-mini/platforms/vxworks/
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|
||||
```
|
||||
Create a VIP based on the VSB. Make sure the following components are added:
|
||||
* INCLUDE_POSIX_PTHREADS
|
||||
* INCLUDE_POSIX_PTHREAD_SCHEDULER
|
||||
* INCLUDE_SHARED_DATA
|
||||
* INCLUDE_SHL
|
||||
|
||||
Copy the generated iwasm executable, the test WASM binary as well as the needed
|
||||
shared libraries (libc.so.1, libllvm.so.1 or libgnu.so.1 depending on the VSB,
|
||||
libunix.so.1) to a supported file system (eg: romfs).
|
||||
|
||||
Note:
|
||||
WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](./build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in VxWorks, interpreter and builtin libc are enabled by default.
|
||||
|
||||
Zephyr
|
||||
-------------------------
|
||||
You need to prepare Zephyr first as described here https://docs.zephyrproject.org/latest/getting_started/index.html#get-zephyr-and-install-python-dependencies.
|
||||
|
||||
After that you need to point the `ZEPHYR_BASE` variable to e.g. `~/zephyrproject/zephyr`. Also, it is important that you have `west` available for subsequent actions.
|
||||
|
||||
``` Bash
|
||||
cd <wamr_root_dir>/product-mini/platforms/zephyr/simple
|
||||
# Execute the ./build_and_run.sh script with board name as parameter. Here take x86 as example:
|
||||
./build_and_run.sh x86
|
||||
```
|
||||
|
||||
If you want to use the Espressif toolchain (esp32 or esp32c3), you can most conveniently install it with `west`:
|
||||
|
||||
``` Bash
|
||||
cd $ZEPHYR_BASE
|
||||
west espressif install
|
||||
```
|
||||
|
||||
After that set `ESPRESSIF_TOOLCHAIN_PATH` according to the output, for example `~/.espressif/tools/zephyr`.
|
||||
|
||||
Note:
|
||||
WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](./build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in Zephyr, interpreter, AOT and builtin libc are enabled by default.

|
||||
or build project with 8-thread by using command below:
|
||||
|
||||
```bash
|
||||
scons -j8
|
||||
```
|
||||
|
||||
after project building, you can got an binary file named `rtthread.bin`, then you can download this file to the MCU board.
|
||||
|
||||
Android
|
||||
-------------------------
|
||||
able to generate a shared library support Android platform.
|
||||
- need an [android SDK](https://developer.android.com/studio). Go and get the "Command line tools only"
|
||||
- look for a command named *sdkmanager* and download below components. version numbers might need to check and pick others
|
||||
- "build-tools;29.0.3"
|
||||
- "cmake;3.10.2.4988404"
|
||||
- "ndk;latest"
|
||||
- "patcher;v4"
|
||||
- "platform-tools"
|
||||
- "platforms;android-29"
|
||||
- add bin/ of the downloaded cmake to $PATH
|
||||
- export ANDROID_HOME=/the/path/of/downloaded/sdk/
|
||||
- export ANDROID_NDK_LATEST_HOME=/the/path/of/downloaded/sdk/ndk/2x.xxx/
|
||||
- ready to go
|
||||
|
||||
Use such commands, you are able to compile with default configurations. Any compiling requirement should be satisfied by modifying product-mini/platforms/android/CMakeList.txt. For example, chaning ${WAMR_BUILD_TARGET} in CMakeList could get different libraries support different ABIs.
|
||||
|
||||
``` shell
|
||||
$ cd product-mini/platforms/android/
|
||||
$ mkdir build
|
||||
$ cd build
|
||||
$ cmake ..
|
||||
$ make
|
||||
$ # check output in distribution/wasm
|
||||
$ # include/ includes all necesary head files
|
||||
$ # lib includes libiwasm.so
|
||||
```
|
||||
|
||||
NuttX
|
||||
-------------------------
|
||||
WAMR is intergrated with NuttX, just enable the WAMR in Kconfig option (Application Configuration/Interpreters).
|
||||
|
||||
ESP-IDF
|
||||
-------------------------
|
||||
WAMR integrates with ESP-IDF both for the XTENSA and RISC-V chips (esp32x and esp32c3 respectively).
|
||||
|
||||
In order to use this, you need at least version 4.3.1 of ESP-IDF.
|
||||
If you don't have it installed, follow the instructions [here](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/#get-started-get-prerequisites).
|
||||
ESP-IDF also installs the toolchains needed for compiling WAMR and ESP-IDF.
|
||||
A small demonstration of how to use WAMR and ESP-IDF can be found under [product_mini](/product-mini/platforms/esp-idf).
|
||||
The demo builds WAMR for ESP-IDF and runs a small wasm program.
|
||||
In order to run it for your specific Espressif chip, edit the [build_and_run.sh](/product-mini/platforms/esp-idf/build_and_run.sh) file and put the correct toolchain file (see #Cross-compilation) and `IDF_TARGET`.
|
||||
Before compiling it is also necessary to call ESP-IDF's `export.sh` script to bring all compile time relevant information in scope.
|
||||
|
||||
Docker
|
||||
-------------------------
|
||||
[Docker](https://www.docker.com/) will download all the dependencies and build WAMR Core on your behalf.
|
||||
|
||||
Make sure you have Docker installed on your machine: [macOS](https://docs.docker.com/docker-for-mac/install/), [Windows](https://docs.docker.com/docker-for-windows/install/) or [Linux](https://docs.docker.com/install/linux/docker-ce/ubuntu/).
|
||||
|
||||
Build *iwasm* with the Docker image:
|
||||
|
||||
``` Bash
|
||||
$ cd ci

||||
$ ./build_wamr.sh
|
||||
$ ls ../build_out/
|
||||
```
|
||||
|
||||
*build_wamr.sh* will generate *linux* compatible libraries ( libiwasm.so and
|
||||
libvmlib.a ) and an executable binary (*iwasm*) and copy *iwasm* to
|

WAMR supports source level debugging based on DWARF (normally used in C/C++/Rust), source map (normally used in AssemblyScript) is not supported.
|
||||
|
||||
**The lldb's ability to debug wasm application is based on the patch [Add class WasmProcess for WebAssembly debugging](https://reviews.llvm.org/D78801). Thanks very much to the author @paolosev for such a great work!**

# Build iwasm
|
||||
|
||||
iwasm is the executable binary built with WAMR VMcore supports WASI and command line interface. Refer to [**how to build wamr vmcore**](../doc/build_wamr.md) for all the supported CMAKE compilation variables.
|
||||
|
||||
If you are building for ARM architecture on a X86 development machine, you can use the `CMAKE_TOOLCHAIN_FILE` to set the toolchain file for cross compling.
|
||||
|
||||
```
|
||||
cmake .. -DCMAKE_TOOLCHAIN_FILE=$TOOL_CHAIN_FILE \
|
||||
-DWAMR_BUILD_PLATFORM=linux \
|
||||
-DWAMR_BUILD_TARGET=ARM
|
||||
```
|
||||
|
||||
Refer to toolchain sample file [`samples/simple/profiles/arm-interp/toolchain.cmake`](../samples/simple/profiles/arm-interp/toolchain.cmake) for how to build mini product for ARM target architecture.
|
||||
|
||||
If you compile for ESP-IDF, make sure to set the right toolchain file for the chip you're using (e.g. `$IDF_PATH/tools/cmake/toolchain-esp32c3.cmake`).
|
||||
Note that all ESP-IDF toolchain files live under `$IDF_PATH/tools/cmake/`.
|
||||
|
||||
## Linux
|
||||
|
||||
First of all please install the dependent packages.
|
||||
Run command below in Ubuntu-18.04:
|
||||
|
||||
``` Bash
|
||||
sudo apt install build-essential cmake g++-multilib libgcc-8-dev lib32gcc-8-dev
|
||||
```
|
||||
Or in Ubuntu-16.04:
|
||||
``` Bash
|
||||
sudo apt install build-essential cmake g++-multilib libgcc-5-dev lib32gcc-5-dev
|
||||
```
|
||||
Or in Fedora:
|
||||
``` Bash
|
||||
sudo dnf install glibc-devel.i686
|
||||
```
|
||||
|
||||
After installing dependencies, build the source code:
|
||||
``` Bash
|
||||
cd product-mini/platforms/linux/
|
||||
mkdir build && cd build
|
||||
cmake ..
|
||||
make
|
||||
# iwasm is generated under current directory
|
||||
```
|
||||
|
||||
By default in Linux, the `fast interpreter`, `AOT` and `Libc WASI` are enabled, and JIT is disabled.
|
||||
And the build target is set to X86_64 or X86_32 depending on the platform's bitwidth.
|
||||
|
||||
There are total 6 running modes supported: fast interpreter, classi interpreter, AOT, LLVM JIT, Fast JIT and Multi-tier JIT.
|
||||
|
||||
(1) To run a wasm file with `fast interpreter` mode - build iwasm with default build and then:
|
||||
```Bash
|
||||
iwasm <wasm file>
|
||||
```
|
||||
Or
|
||||
```Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_INTERP=1
|
||||
make
|
||||
```
|
||||
|
||||
(2) To disable `fast interpreter` and enable `classic interpreter` instead:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_FAST_INTERP=0
|
||||
make
|
||||
```
|
||||
|
||||
(3) To run an AOT file, firstly please refer to [Build wamrc AOT compiler](../wamr-compiler/README.md) to build wamrc, and then:
|
||||
```Bash
|
||||
wamrc -o <AOT file> <WASM file>
|
||||
iwasm <AOT file>
|
||||
```
|
||||
|
||||
(4) To enable the `LLVM JIT` mode, firstly we should build the LLVM library:
|
||||
``` Bash
|
||||
cd product-mini/platforms/linux/
|
||||
./build_llvm.sh (The llvm source code is cloned under <wamr_root_dir>/core/deps/llvm and auto built)
|
||||
```
|
||||
|
||||
Then pass argument `-DWAMR_BUILD_JIT=1` to cmake to enable LLVM JIT:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_JIT=1
|
||||
make
|
||||
```
|
||||
|
||||
Note:
|
||||
By default, the LLVM Orc JIT with Lazy compilation is enabled to speedup the lanuching process and reduce
|
||||
the JIT compilation time by creating backend threads to compile the WASM functions parallely, and for the
|
||||
main thread, the functions in the module will not be compiled until they are firstly called and haven't been
|
||||
compiled by the compilation threads.
|
||||
|
||||
If developer wants to disable the Lazy compilation, we can:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_JIT=1 -DWAMR_BUILD_LAZY_JIT=0
|
||||
make
|
||||
```
|
||||
In which all the WASM functions will be previously compiled before main thread starts to run the wasm module.
|
||||
|
||||
(5) To enable the `Fast JIT` mode:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_FAST_JIT=1
|
||||
make
|
||||
```
|
||||
The Fast JIT is a lightweight JIT engine with quick startup, small footprint and good portability, and gains ~50% performance of AOT.
|
||||
|
||||
(6) To enable the `Multi-tier JIT` mode:
|
||||
``` Bash
|
||||
mkdir build && cd build
|
||||
cmake .. -DWAMR_BUILD_FAST_JTI=1 -DWAMR_BUILD_JIT=1
|
||||
make
|
||||
```
|
||||
The Multi-tier JIT is a two level JIT tier-up engine, which launchs Fast JIT to run the wasm module as soon as possible and creates backend threads to compile the LLVM JIT functions at the same time, and when the LLVM JIT functions are compiled, the runtime will switch the extecution from the Fast JIT jitted code to LLVM JIT jitted code gradually, so as to gain the best performance.
|
||||
|
||||
## Linux SGX (Intel Software Guard Extension)
|
||||
|
||||
|
||||
Please see [Build and Port WAMR vmcore for Linux SGX](../doc/linux_sgx.md) for the details.
|
||||
|
||||
## MacOS
|
||||
|
||||
|
||||
Make sure to install Xcode from App Store firstly, and install cmake.
|
||||
|

|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|
||||
# iwasm is generated under current directory
|
||||
```
|
||||
By default in MacOS, the `fast interpreter`, `AOT` and `Libc WASI` are enabled, and JIT is disabled.
|
||||
And the build target is set to X86_64 or X86_32 depending on the platform's bitwidth.
|
||||
|
||||
To run a wasm file with interpreter mode:
|
||||
```Bash
|
||||
iwasm <wasm file>
|
||||
```
|
||||
To run an AOT file, firstly please refer to [Build wamrc AOT compiler](../wamr-compiler/README.md) to build wamrc, and then:
|
||||
```Bash
|
||||
wamrc -o <AOT file> <WASM file>
|
||||
iwasm <AOT file>
|
||||
```
|
||||
Note:
|
||||
For how to build the `JIT` mode and `classic interpreter` mode, please refer to [Build iwasm on Linux](../doc/build_wamr.md#linux).
|
||||
|
||||
WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](../doc/build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in MacOS, interpreter, AOT, and builtin libc are enabled by default.
|
||||
|
||||
## Windows
|
||||
|
||||
|
||||
Make sure `MSVC` and `cmake` are installed and available in the command line environment
|
||||
|
||||
Then build the source codes:
|
||||
``` Bash
|
||||
cd product-mini/platforms/windows/
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
cmake --build . --config Release
|
||||
# ./Release/iwasm.exe is generated
|
||||
```
|
||||
|
||||
By default in Windows, the `fast interpreter`, `AOT` and `Libc WASI` are enabled, and JIT is disabled.
|
||||
|
||||
To run a wasm file with interpreter mode:
|
||||
```Bash
|
||||
iwasm.exe <wasm file>
|
||||
```
|
||||
To run an AOT file, firstly please refer to [Build wamrc AOT compiler](../wamr-compiler/README.md) to build wamrc, and then:
|
||||
```Bash
|
||||
wamrc.exe -o <AOT file> <WASM file>
|
||||
iwasm.exe <AOT file>
|
||||
```
|
||||
Note:
|
||||
For how to build the `JIT` mode and `classic interpreter` mode, please refer to [Build iwasm on Linux](../doc/build_wamr.md#linux).
|
||||
|
||||
WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](../doc/build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in Windows, interpreter, AOT, and builtin libc are enabled by default.
|
||||
|
||||
## MinGW
|
||||
|
||||
|
||||
First make sure the correct CMake package is installed; the following commands
|
||||
are valid for the MSYS2 build environment:
|
||||
|
||||
```Bash
|
||||
pacman -R cmake
|
||||
pacman -S mingw-w64-x86_64-cmake
|
||||
pacman -S mingw-w64-x86_64-gcc
|
||||
pacman -S make git
|
||||
```
|
||||
|
||||
Then follow the build instructions for Windows above, and add the following
|
||||
arguments for cmake:
|
||||
|
||||
```Bash
|
||||
cmake .. -G"Unix Makefiles" \
|
||||
-DWAMR_DISABLE_HW_BOUND_CHECK=1
|
||||
````
|
||||
|
||||
Note that WASI will be disabled until further work is done towards full MinGW support.
|
||||
|
||||
- Since memory access boundary check with hardware trap feature is disabled, when generating the AOT file with `wamrc`, the `--bounds-checks=1` flag should be added to generate the memory access boundary check instructions to ensure the sandbox security:
|
||||
```bash
|
||||
wamrc --bounds-checks=1 -o <aot_file> <wasm_file>
|
||||
```
|
||||
- Compiler complaining about missing `UnwindInfoAddress` field in `RUNTIME_FUNCTION`
|
||||
struct (winnt.h).
|
||||
|
||||
|
||||
## VxWorks
|
||||
|
||||
VxWorks 7 SR0620 release is validated.
|
||||
|
||||
First you need to build a VSB. Make sure *UTILS_UNIX* layer is added in the VSB.
|
||||
After the VSB is built, export the VxWorks toolchain path by:
|
||||
```bash
|
||||
export <vsb_dir_path>/host/vx-compiler/bin:$PATH
|
||||
```
|
||||
Now switch to iwasm source tree to build the source code:
|
||||
```bash
|
||||
cd product-mini/platforms/vxworks/
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ..
|
||||
make
|
||||
```
|
||||
Create a VIP based on the VSB. Make sure the following components are added:
|
||||
* INCLUDE_POSIX_PTHREADS
|
||||
* INCLUDE_POSIX_PTHREAD_SCHEDULER
|
||||
* INCLUDE_SHARED_DATA
|
||||
* INCLUDE_SHL
|
||||
|
||||
Copy the generated iwasm executable, the test WASM binary as well as the needed
|
||||
shared libraries (libc.so.1, libllvm.so.1 or libgnu.so.1 depending on the VSB,
|
||||
libunix.so.1) to a supported file system (eg: romfs).
|
||||
|
||||
Note:
|
||||
WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](../doc/build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in VxWorks, interpreter and builtin libc are enabled by default.
|
||||
|
||||
## Zephyr
|
||||
|
||||
You need to prepare Zephyr first as described here https://docs.zephyrproject.org/latest/getting_started/index.html#get-zephyr-and-install-python-dependencies.
|
||||
|
||||
After that you need to point the `ZEPHYR_BASE` variable to e.g. `~/zephyrproject/zephyr`. Also, it is important that you have `west` available for subsequent actions.
|
||||
|
||||
``` Bash
|
||||
cd <wamr_root_dir>/product-mini/platforms/zephyr/simple
|
||||
# Execute the ./build_and_run.sh script with board name as parameter. Here take x86 as example:
|
||||
./build_and_run.sh x86
|
||||
```
|
||||
|
||||
If you want to use the Espressif toolchain (esp32 or esp32c3), you can most conveniently install it with `west`:
|
||||
|
||||
``` Bash
|
||||
cd $ZEPHYR_BASE
|
||||
west espressif install
|
||||
```
|
||||
|
||||
After that set `ESPRESSIF_TOOLCHAIN_PATH` according to the output, for example `~/.espressif/tools/zephyr`.
|
||||
|
||||
Note:
|
||||
WAMR provides some features which can be easily configured by passing options to cmake, please see [WAMR vmcore cmake building configurations](../doc/build_wamr.md#wamr-vmcore-cmake-building-configurations) for details. Currently in Zephyr, interpreter, AOT and builtin libc are enabled by default.
|
||||
|
||||
|
||||
## RT-Thread
|
||||
|
||||
|
||||
1. Get rt-thread [system codes](https://github.com/RT-Thread/rt-thread).
|
||||
|
||||
2. Enable WAMR software package with menuconfig tool which provided by RT-Thread.
|
||||
|
||||
* Environment in Linux, run command below:
|
||||
|
||||
```bash
|
||||
scons --menuconfig
|
||||
```
|
||||
|
||||
* Environment in Windows ConEmu, run command below:
|
||||
|
||||
```bash
|
||||
menuconfig
|
||||
```
|
||||
|
||||
Select and enable `WAMR` in:
|
||||
|
||||
* RT-Thread online packages
|
||||
* tools packages
|
||||
* WebAssembly Micro Runtime (WAMR)
|
||||
|
||||
3. Configure `WAMR` with menuconfig tool.
|
||||
|
||||
you can choice features of iwasm below:
|
||||
|
||||
* Enable testing parameters of iwasm
|
||||
* Enable interpreter Mode / Fast interpreter Mode
|
||||
* Use built-libc
|
||||
* Enable AOT
|
||||
|
||||
4. Exit menuconfig tool and save configure, update and download package.
|
||||
|
||||
```bash
|
||||
pkgs --update
|
||||
```
|
||||
|
||||
5. build project and download the binary to boards.
|
||||
|
||||
```bash
|
||||
scons
|
||||
```
|
||||
|
||||
or build project with 8-thread by using command below:
|
||||
|
||||
```bash
|
||||
scons -j8
|
||||
```
|
||||
|
||||
after project building, you can got an binary file named `rtthread.bin`, then you can download this file to the MCU board.
|
||||
|
||||
## Android
|
||||
|
||||
able to generate a shared library support Android platform.
|
||||
- need an [android SDK](https://developer.android.com/studio). Go and get the "Command line tools only"
|
||||
- look for a command named *sdkmanager* and download below components. version numbers might need to check and pick others
|
||||
- "build-tools;29.0.3"
|
||||
- "cmake;3.10.2.4988404"
|
||||
- "ndk;latest"
|
||||
- "patcher;v4"
|
||||
- "platform-tools"
|
||||
- "platforms;android-29"
|
||||
- add bin/ of the downloaded cmake to $PATH
|
||||
- export ANDROID_HOME=/the/path/of/downloaded/sdk/
|
||||
- export ANDROID_NDK_LATEST_HOME=/the/path/of/downloaded/sdk/ndk/2x.xxx/
|
||||
- ready to go
|
||||
|
||||
Use such commands, you are able to compile with default configurations. Any compiling requirement should be satisfied by modifying product-mini/platforms/android/CMakeList.txt. For example, chaning ${WAMR_BUILD_TARGET} in CMakeList could get different libraries support different ABIs.
|
||||
|
||||
``` shell
|
||||
$ cd product-mini/platforms/android/
|
||||
$ mkdir build
|
||||
$ cd build
|
||||
$ cmake ..
|
||||
$ make
|
||||
$ # check output in distribution/wasm
|
||||
$ # include/ includes all necesary head files
|
||||
$ # lib includes libiwasm.so
|
||||
```
|
||||
|
||||
## NuttX
|
||||
|
||||
WAMR is intergrated with NuttX, just enable the WAMR in Kconfig option (Application Configuration/Interpreters).
|
||||
|
||||
## ESP-IDF
|
||||
|
||||
WAMR integrates with ESP-IDF both for the XTENSA and RISC-V chips (esp32x and esp32c3 respectively).
|
||||
|
||||
In order to use this, you need at least version 4.3.1 of ESP-IDF.
|
||||
If you don't have it installed, follow the instructions [here](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/#get-started-get-prerequisites).
|
||||
ESP-IDF also installs the toolchains needed for compiling WAMR and ESP-IDF.
|
||||
A small demonstration of how to use WAMR and ESP-IDF can be found under [product_mini](./platforms/esp-idf).
|
||||
The demo builds WAMR for ESP-IDF and runs a small wasm program.
|
||||
In order to run it for your specific Espressif chip, edit the [build_and_run.sh](./platforms/esp-idf/build_and_run.sh) file and put the correct toolchain file (see #Cross-compilation) and `IDF_TARGET`.
|
||||
Before compiling it is also necessary to call ESP-IDF's `export.sh` script to bring all compile time relevant information in scope.
|
||||
|
||||
## Docker
|
||||
|
||||
[Docker](https://www.docker.com/) will download all the dependencies and build WAMR Core on your behalf.
|
||||
|
||||
Make sure you have Docker installed on your machine: [macOS](https://docs.docker.com/docker-for-mac/install/), [Windows](https://docs.docker.com/docker-for-windows/install/) or [Linux](https://docs.docker.com/install/linux/docker-ce/ubuntu/).
|
||||
|
||||
Build *iwasm* with the Docker image:
|
||||
|
||||
``` Bash
|
||||
$ cd ci
|
||||
$ ./build_wamr.sh
|
||||
$ ls ../build_out/
|
||||
```
|
||||
|
||||
*build_wamr.sh* will generate *linux* compatible libraries ( libiwasm.so and
|
||||
libvmlib.a ) and an executable binary (*iwasm*) and copy *iwasm* to
|
||||
*build_out*. All original generated files are still under
|
||||
*product-mini/platforms/linux/build*.
|
||||
|
||||
## FreeBSD
|
||||
|
||||
First, install the dependent packages:
|
||||
```shell
|
||||
sudo pkg install gcc cmake wget
|
||||
```
|
||||
|
||||
Then you can run the following commands to build iwasm with default configurations:
|
||||
```shell
|
||||
cd product-mini/platforms/freebsd
|
||||
mkdir build && cd build
|
||||
cmake ..
|
||||
make
|
||||
```
|
||||
|
||||
|
||||
## AliOS-Things
|
||||
|
||||
1. a developerkit board id needed for testing
|
||||
2. download the AliOS-Things code
|
||||
``` Bash
|
||||
git clone https://github.com/alibaba/AliOS-Things.git
|
||||
```
|
||||
3. copy <wamr_root_dir>/product-mini/platforms/alios-things directory to AliOS-Things/middleware, and rename it as iwasm
|
||||
``` Bash

|
||||
```
|
||||
|
||||
For developerkit:
|
||||
Modify file middleware/iwasm/aos.mk, patch as:
|
||||
|
||||
``` C
|
||||

# Samples
|
||||
- [**basic**](./basic): Demonstrating how to use runtime exposed API's to call WASM functions, how to register native functions and call them, and how to call WASM function from native function.
|
||||
- **[simple](./simple/README.md)**: The runtime is integrated with most of the WAMR APP libraries, and a few WASM applications are provided for testing the WAMR APP API set. It uses **built-in libc** and executes apps in **interpreter** mode by default.
|
||||
- **[file](./file/README.md)**: Demonstrating the supported file interaction API of WASI. This sample can also demonstrate the SGX IPFS (Intel Protected File System), enabling an enclave to seal and unseal data at rest.
|
||||
- **[littlevgl](./littlevgl/README.md)**: Demonstrating the graphic user interface application usage on WAMR. The whole [LVGL](https://github.com/lvgl/lvgl) 2D user graphic library and the UI application are built into WASM application. It uses **WASI libc** and executes apps in **AOT mode** by default.
|
||||
- **[gui](./gui/README.md)**: Move the [LVGL](https://github.com/lvgl/lvgl) library into the runtime and define a WASM application interface by wrapping the littlevgl API. It uses **WASI libc** and executes apps in **interpreter** mode by default.
|
||||
- **[multi-thread](./multi-thread/)**: Demonstrating how to run wasm application which creates multiple threads to execute wasm functions concurrently, and uses mutex/cond by calling pthread related API's.
|
||||
- **[spawn-thread](./spawn-thread)**: Demonstrating how to execute wasm functions of the same wasm application concurrently, in threads created by host embedder or runtime, but not the wasm application itself.
|
||||
- **[multi-module](./multi-module)**: Demonstrating the [multiple modules as dependencies](./doc/multi_module.md) feature which implements the [load-time dynamic linking](https://webassembly.org/docs/dynamic-linking/).
|
||||
- **[ref-types](./ref-types)**: Demonstrating how to call wasm functions with argument of externref type introduced by [reference types proposal](https://github.com/WebAssembly/reference-types).
|
||||
- **[wasm-c-api](./wasm-c-api/README.md)**: Demonstrating how to run some samples from [wasm-c-api proposal](https://github.com/WebAssembly/wasm-c-api) and showing the supported API's.
|
||||
- **[socket-api](./socket-api/README.md)**: Demonstrating how to run wasm tcp server and tcp client applications, and how they communicate with each other.
|
||||
- **[workload](./workload/README.md)**: Demonstrating how to build and run some complex workloads, e.g. tensorflow-lite, XNNPACK, wasm-av1, meshoptimizer and bwa.
|
||||
- **[sgx-ra](./sgx-ra/README.md)**: Demonstrating how to execute Remote Attestation on SGX with [librats](https://github.com/inclavare-containers/librats), which enables mutual attestation with other runtimes or other entities that support librats to ensure that each is running within the TEE.

### Build wamrc AOT compiler
|
||||
|
||||
Both wasm binary file and AOT file are supported by iwasm. The wamrc AOT compiler is to compile wasm binary file to AOT file which can also be run by iwasm. Execute following commands to build **wamrc** compiler for Linux:
|
||||
|
||||
```shell
|
||||
cd wamr-compiler
|
||||
./build_llvm.sh (or "./build_llvm_xtensa.sh" to support xtensa target)
|
||||
mkdir build && cd build
|
||||
cmake .. (or "cmake .. -DWAMR_BUILD_PLATFORM=darwin" for MacOS)
|
||||
make
|
||||
# wamrc is generated under current directory
|
||||
```
|
||||
|
||||
For **Windows**：
|
||||
```shell
|
||||
cd wamr-compiler
|
||||
python build_llvm.py
|
||||
mkdir build && cd build
|
||||
cmake ..
|
||||
cmake --build . --config Release
|
||||
# wamrc.exe is generated under .\Release directory
|

```

# WebAssembly Micro Runtime SDK
|
||||
|
||||
Usually there are two tasks for integrating the WAMR into a particular project:
|
||||
|
||||
- Select what WAMR components (vmcore, libc, app-mgr, app-framework components) to be integrated, and get the associated source files added into the project building configuration
|
||||
- Generate the APP SDK for developing the WASM apps on the selected libc and framework components
|
||||
|
||||
The **[WAMR SDK](./wamr-sdk)** tools is helpful to finish the two tasks quickly. It supports menu configuration for selecting WAMR components and builds the WAMR to a SDK package that includes **runtime SDK** and **APP SDK**. The runtime SDK is used for building the native application and the APP SDK should be shipped to WASM application developers.
|
||||
|
||||
|
||||
**Note**: [WASI-SDK](https://github.com/CraneStation/wasi-sdk/releases) version 7 and above should be installed before building the WAMR SDK.
