Build with WasmEdge zlib Plug-in
The WasmEdge zlib plug-in provides zlib compression and decompression functionality to WebAssembly applications running on WasmEdge. It allows Wasm modules that depend on zlib (such as those compiled from C/C++ with zlib linkage) to use the host system's zlib implementation directly.
Prerequisites
Install zlib development headers on your system.
For Ubuntu:
sudo apt update
sudo apt install -y zlib1g-dev
For macOS:
brew install zlib
Build WasmEdge with the zlib Plug-in
To enable the WasmEdge zlib plug-in, developers need to build WasmEdge from source with the cmake option -DWASMEDGE_PLUGIN_ZLIB=ON.
cd <path/to/your/wasmedge/source/folder>
cmake -GNinja -Bbuild -DCMAKE_BUILD_TYPE=Release -DWASMEDGE_PLUGIN_ZLIB=ON
cmake --build build
cmake --install build
If the built wasmedge CLI tool cannot find the zlib plug-in, you can set the WASMEDGE_PLUGIN_PATH environment variable to the plug-in installation path (such as /usr/local/lib/wasmedge/, or the built plug-in path build/plugins/wasmedge_zlib/) to try to fix this issue.
Then you will have an executable wasmedge runtime under /usr/local/bin and the zlib plug-in under /usr/local/lib/wasmedge/libwasmedgePluginWasmEdgeZlib.so (or .dylib on macOS) after installation.
