This repository contains infrastructure to test the various WebAssembly runtimes, to see how compatible they are with the official wasm-c-api.
Install the commands listed under the Prerequisites section.
Then execute the file test_runtimes.sh.
The wasm-c-api project provides the official C API for WebAssembly
runtimes. It does so by publishing the file wasm.h. This project also
provides some example programs to demonstrate the features of WebAssembly, and
also demonstrate how to embed a WebAssembly runtime in C programs.
The test_runtimes.sh script downloads the wasm-c-api code. For each
WebAssembly runtime, it then downloads code of the runtime, and compiles the
runtime into a library. It then builds the example programs provided by the
wasm-c-api project. To build the examples, the script uses the wasm.h file
published by the wasm-c-api project, and the library from the runtime. It
finally runs the resulting executable, to determine if the example works
successfully with the runtime under test.
- Git
- Make
- Rust and Cargo; commands from the Rust ecosystem.
- A C compiler (script invokes it using
cccommand).
