WAMR supports *wasm-c-api* in both *interpreter* mode and *aot* mode.
|
|
|
|
|
|
|
|
|
|
Before staring, we need to download and intall [WABT](https://github.com/WebAssembly/wabt/releases/latest).
|
|
|
|
|
|
|
|
|
|
``` shell
|
|
|
|
|
$ cd /opt
|
|
|
|
|
$ wget https://github.com/WebAssembly/wabt/releases/download/1.0.19/wabt-1.0.19-ubuntu.tar.gz
|
|
|
|
|
$ tar -xzf wabt-1.0.19-ubuntu.tar.gz
|
|
|
|
|
$ mv wabt-1.0.19 wabt
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
By default, all samples are compiled and run in "interpreter" mode.

``` shell

$ mkdir build
|
|
|
|
|
$ cd build
|
|
|
|
|
$ cmake ..
|
|
|
|
|
$ make
|
|
|
|
|
$ # it will build a library with c-api supporting.
|
|
|
|
|
$ # Also copy *.wasm from ../src/
|
|
|
|
|
$ # and generate executable files
|
|
|
|
|
$ # now, it is ok to run samples
|
|
|
|
|
$ ./hello
|
|
|
|
|
$ ...
|
|
|
|
|
$ ./global
|
|
|
|
|
$ ...
|
|
|
|
|
$ ./callback
|
|
|
|
|
$ ...
|
|
|
|
|
```
|
|
|

They can be compiled and run in *aot* mode when some compiling flags are given.
|
|
|
|
|
|
|
|
|
|
``` shell
|
|
|
|
|
$ mkdir build
|
|
|
|
|
$ cd build
|
|
|
|
|
$ cmake -DWAMR_BUILD_INTERP=0 -DWAMR_BUILD_AOT=1 ..
|
|
|
|
|
$ make
|
|
|
|
|
$ # it will build a library with c-api supporting.
|
|
|
|
|
$ # Also copy *.wasm from ../src/
|
|
|
|
|
$ # and transform *.wasm to *.aot
|
|
|
|
|
$ # and generate executable files
|
|
|
|
|
$ # now, it is ok to run samples
|
|
|
|
|
$ ./hello
|
|
|
|
|
$ ...
|
|
|

$ ./global
|
