Josh Triplett 548926ab1a Rename "master" branch to "main"
Update all links accordingly. Also update links to other repositories
whose branches have renamed.

The references to repositories whose branches have not renamed should be
referencing specific commits anyway, so reference those specific commits
by hash.

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
