## Build


You can build from source or use pre-built binaries. It depends on how you set ENV variables.

- Use pre-built binaries
- Build from git submodules

## Use pre-built binaries


Download latest binary release of [libplctag](https://github.com/libplctag/libplctag/releases) and extract it to somewhere of your computer.

Set environment variable `LIBPLCTAG_PATH` to the directory of extracted binaries.

## Build from git submodules


If environment variable `LIBPLCTAG_PATH` does not present, will build from git submodules [libplctag](https://github.com/libplctag/libplctag/).
