3.14 is used and tested by linux mini-product to fix ``` CMake Error at CMakeLists.txt:4 (cmake_minimum_required): Compatibility with CMake < 3.5 has been removed from CMake. Update the VERSION argument <min> value. Or, use the <min>...<max> syntax to tell CMake that the project requires at least <min> but has been updated to work with policies introduced by <max> or earlier. Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway. ```

# wasm-micro-runtime as ESP-IDF component
|
|
|
|
You can build an ESP-IDF project with wasm-micro-runtime as a component:
|
|
|
|
- Make sure you have the ESP-IDF properly installed and setup
|
|
- In particular have the following paths set:
|
|
- `WAMR_PATH` to point to your wasm-micro-runtime repository
|
|
- `IDF_PATH` to point to your ESP-IDF
|
|
- `source $IDF_PATH/export.sh`
|
|
- Create a new project, e.g.: `idf.py create-project wamr-hello`
|
|
- In the newly created project folder edit the `CMakeList.txt`:
|
|
|
|
```
|
|
cmake_minimum_required(VERSION 3.14)
|
|
|
|
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
|
|
|
|
set (COMPONENTS ${IDF_TARGET} main freertos esptool_py wamr)
|
|
|
|
list(APPEND EXTRA_COMPONENT_DIRS "$ENV{WAMR_PATH}/build-scripts/esp-idf")
|
|
|
|
project(wamr-hello)
|
|
```
|
|
- Develop your project in it's `main` component folder.
|
|
|
|
You can find an example [here](../../product-mini/platforms/esp-idf).
|
|
|
|
- Set target platform: `idf.py set-target esp32c3`
|
|
- Build: `idf.py build`
|
|
- Flash: `idf.py flash`
|
|
- Check the output: `idf.py monitor` |
