Known issues

gotchaFlawfinder is a command-line tool, not a Python library designed for import. Attempting to import 'flawfinder' as a module may work but is not officially supported and may break.

fix

Use subprocess or os.system to call flawfinder from Python.

affects: All

deprecatedFlawfinder has not been updated since 2019; requires Python >=2.7. It may not work on Python 3.10+ without adjustments.

fix

Consider alternatives like Cppcheck or clang-tidy for modern C/C++ analysis.

affects: >=2.0.19
