Autotools insists on generating pyo and pyc files when building my project (not when running it) no matter what I do. The problem is that my Python configuration is somewhat strange, and I don’t want the Python compiler to run during installation. Is there any way to disable generating these files?

For reference, here are the things I’ve tried:

  • Setting py_compile=echo so that automake won’t compile Python scripts
  • Manually defining install-pythonPYTHON in Makefile.am
  • Setting PYTHONFLAGS=-B
  • Setting PYTHONDONTWRITEBYTECODE in Makefile.am, configure.ac, etc.
  • Creating a new automake variable “python2dir” and installing the script using dist_python2_DATA = Script.py

Basically, if a file ends with the .py extension, Automake WILL create pyc and pyo files, no matter what you do.

    Please try again with your last attempt.

    dist_python_DATA = foo.py

    will treat foo.py as any regular file, distribute it, and install it in $(pythondir). _DATA does not trigger any kind of compilation.
