This repo shows how you can convert a normal C library to an Extism Plugin. miniz is a minimal compression library.
- Fetch all submodules
git submodule update --init --recursive
- Download WASI SDK
cd dependencies/extism-pdk
./install-wasi-sdk.sh
This downloads WASI SDK to dependencies/extism-pdk/wasi-sdk.
- Build
cd plugin
mkdir build
cd build
cmake cmake -D CMAKE_C_COMPILER=$(pwd)/../../dependencies/extism-pdk/wasi-sdk/bin/clang ..
make
Now you should be able to find a miniz_extism.wasm in plugin/build.
- Test
cd host
go run .
You should get an output similar to this:
PS D:\x\wasm\miniz_extism\host> go run .
