The "basic" sample project
|
|
==============
|
|
|
|
This sample demonstrates a few basic usages of embedding WAMR:
|
|
- initialize runtime
|
|
- load wasm app and instantiate the module
|
|
- call wasm function and pass arguments
|
|
- export native functions to the WASM apps
|
|
- wasm function calls native function and pass arguments
|
|
- deinitialize runtime
|
|
|
|
Build this sample
|
|
==============
|
|
Execute the ```build.sh``` script then all binaries including wasm application files would be generated in 'out' directory.
|
|
|
|
```
|
|
$ ./build.sh
|
|
```
|
|
|
|
Run the sample
|
|
==========================
|
|
Enter the out directory.
|
|
```
|
|
$ cd ./out/
|
|
$
|
|
$ ./basic -f wasm-apps/testapp.wasm
|
|
calling into WASM function: generate_float
|
|
Native finished calling wasm function generate_float(), returned a float value: 102009.921875f
|
|
calling into WASM function: float_to_string
|
|
calling into native function: intToStr
|
|
calling into native function: get_pow
|
|
calling into native function: intToStr
|
|
Native finished calling wasm function: float_to_string, returned a formatted string: 102009.921
|
|
```
|
|
Or execute the ```run.sh``` script in ```samples/basic``` folder.
|
|
```
|
|
$ ./run.sh
|
|
