F2PY fails to wrap subroutine with call-back function on Windows for Python 64 bits with MinGW-W64

[ragonneau]

Reproducing code example:

The first example of the official documentation does not work on Windows for any version of Python 64 bits with MinGW-W64 (bin of MinGW-W64 added to PATH, compiler precised by --compiler=mingw32). Thank you!!

Your error message seems to be missing all of its newlines. Could you paste it again?

turned many spaces into newlines. It seems the python.lib is not linked

Thank you for the modification! While trying with 32 bits version of Python and MinGW, it however works. The error occurs only when trying with 64 bits versions.

Is it an error I can handle in the code? Thank you!

Possibly related to #16416 or #16031, both of which also report f2py issues on with windows/mingw
