f2py: pyf file mentioned in sources of an Extension is not added to source distribution #19441
Description
In my project, I have an extension generated from Fortran source code. The generated pyf file needed to be tweaked a bit, and must therefore be treated as a source file as well.
Problem is that, although the pyf file is mentioned as a source file in the Extension, it is not packaged in the source distribution. As, a result, when you try to install from the source tar-ball, the build will fail.
Reproducing code example:
The error cannot be reproduced with a single python file. I created a small demo project that reproduces the error. See https://github.com/gmloose/f2py_hello.
The README.md file describes the steps you have to take in order to reproduce the error.
Error message:
If you follow the steps in the README.md file, you will see the following error message:
build_src

target build/src.linux-x86_64-3.6/hello/_hellomodule.c does not exist:

NumPy/Python version information:
python3 -c 'import sys, numpy; print("Numpy version:{}\nPython version:{}".format(numpy.__version__, sys.version))'
Numpy version:1.19.5
Python version:3.6.9 (default, Jan 26 2021, 15:33:00)
[GCC 8.4.0]
Note that this is the latest numpy version that supports Python 3.6. It was automatically installed in the virtual environment when I installed my demo project.

As a workaround, try including the pyf file in
MANIFEST.infile.gmloose commentedon Jul 9, 2021
This solves the issue of having the
pyffile in the binary distribution. But it is still a workaround. I think the real issue is in the way Numpy'sExtensionhandlespyffiles mentioned assources, which IMHO is a bug. It shouldn't be necessary to manually add thepyffile to eitherMANIFEST.inor aspackage_dataargument tosetup().pearu commentedon Jul 9, 2021
Yes, it is a bug: the
pyffiles should always be considered source files.gmloose commentedon Jan 21, 2022
Any idea when this will be fixed?

Closing as distutils isn't supported anymore. Please use
