# Wasm3 development notes
|
|
|
|
This project uses CMake.
|
|
General build steps look like:
|
|
```sh
|
|
mkdir -p build
|
|
cd build
|
|
cmake ..
|
|
make -j8
|
|
```
|
|
|
|
Wasm3 is continuously tested with Clang, GCC, MSVC compilers, and on multiple platforms.
|
|
It can be easily integarted into any build system, as shown in `platforms`.
|
|
|
|
## Build on Linux, OS X

|
|
ninja
|
|
```
|
|
|
|
### GCC

### Build with MSBuild
|
|
|
|
```sh
|
|
# Create a build directory as usual, then build a specific configuration
|
|
mkdir build
|
|
cd build
|
|
|
|
# Clang, x64
|
|
cmake -G"Visual Studio 16 2019" -A x64 -T ClangCL ..
|
|
cmake --build . --config Release
|
|
|
|
# Clang, x86
|
|
cmake -G"Visual Studio 16 2019" -A Win32 -T ClangCL ..
|
|
cmake --build . --config Release
|
|
|
|
# MSVC, x64
|
|
cmake -G"Visual Studio 16 2019" -A x64 ..
|
|
cmake --build . --config Release
|
|
|
|
# MSVC, x86
|
|
cmake -G"Visual Studio 16 2019" -A Win32 ..
|
|
cmake --build . --config Release
|
|
```

|
|
|
### Build with Ninja
|
|
|
|
```sh
|
|
# Clang
|
|
cmake -GNinja -DCLANG_CL=1 ..
|
|
ninja
|
|
|
|
# MSVC
|
|
cmake -GNinja ..
|
|
ninja
|
|
```
|
|
|
|
## Build for microcontrollers
|
|
|
|
In `./platforms/` folder you can find projects for different targets. Some of them are using Platformio, so you can follow the regular pio build process. Others have custom instructions in respective `README.md` files.
