Build WasmEdge With WasmEdge-Process Plug-in

The WasmEdge Process plug-in provides a sandboxed environment to execute system processes in a secured manner. This guide will walk you through the steps to build the WasmEdge Process plug-in.

Prerequisites

The prerequisites of the WasmEdge-Process plug-in is the same as the WasmEdge building environment on the Linux platforms.

Build WasmEdge with WasmEdge-Process Plug-in

To enable the WasmEdge WasmEdge-Process, developers need to building the WasmEdge from source with the cmake option -DWASMEDGE_PLUGIN_PROCESS=On.

cd <path/to/your/wasmedge/source/folder>
cmake -GNinja -Bbuild -DCMAKE_BUILD_TYPE=Release -DWASMEDGE_PLUGIN_PROCESS=On
cmake --build build
# For the WasmEdge-Process plug-in, you should install this project.
cmake --install build

備註

If the built wasmedge CLI tool cannot find the WasmEdge-Process 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_process/) to try to fix this issue.

Then you will have an executable wasmedge runtime under /usr/local/bin and the WasmEdge-Process plug-in under /usr/local/lib/wasmedge/libwasmedgePluginWasmEdgeProcess.so after installation.

Usage

To use the plug-in with WasmEdge, you need to specify it when starting the WasmEdge runtime:

wasmedge --dir .:. --reactor --process_plugin target/release/libwasmedge_process.so your_wasm_file.wasm

Replace your_wasm_file.wasm with the path to your WebAssembly file. The --process_pluginflag specifies the path to the Process plug-in.

That's it! You have successfully built and installed the WasmEdge Process plug-in.
