Installation

Prebuilt binaries​

The fastest way to get iec-checker is to grab a prebuilt binary from the GitHub releases page. Builds are published for:

  • Linux x86_64
  • Windows x86_64

Download the archive, extract it, and the iec_checker binary is ready to run.

Build from source​

Linux​

Install OCaml 5.1 or later and opam, then clone the repository and install the dependencies:

git clone https://github.com/iec-checker/iec-checker.git
cd iec-checker
opam install --deps-only .

Build the binary:

make build

The executable is now at bin/iec_checker.

Windows​

Install OCaml for Windows following the installation guide. Then open the Cygwin shell, clone the repository, and follow the Linux build steps above.

Optional: Python wrapper and test suite​

The checker.py script wraps the OCaml binary and adds extras like extended formatting and Python plugin support. The test suite is also written in Python.

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
pip install -r requirements-dev.txt
make test

Verify the install​

Run iec-checker against the bundled demo programs:

bin/iec_checker test/st/*.st

You should see one or more warnings printed to stdout. If you do, you're ready — head to the CLI reference for the full flag list.
