Build

Set the WASI_SDK_PREFIX environment variable before building (see architecture-specific instructions below). Alternatively, use cmake's -DWASI_SDK_PREFIX=.... option. Also make sure nodejs 14, npm 6.14, and yarn 1.22 are in your path.

git submodule update --init --recursive
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j
ctest -j

To speed up builds, use -DCMAKE_CXX_COMPILER_LAUNCHER=ccache -DCMAKE_C_COMPILER_LAUNCHER=ccache
