Currently when calling wasm_runtime_call_wasm() to invoke wasm function with externref type argument from runtime embedder, developer needs to use wasm_externref_obj2ref() to convert externref obj into an internal ref index firstly, which is not convenient to developer. To align with GC feature in which all the references passed to wasm_runtime_call_wasm() can be object pointers directly, we change the interface of wasm_runtime_call_wasm() to allow to pass object pointer directly for the externref argument, and refactor the related codes, update the related samples and the document. |

WAMR supports wasm-c-api in both interpreter mode and aot mode.
Before staring, we need to download and intall WABT.
$ 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.
$ 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.
$ 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
$ ...
$ ./callback
