Hello everyone, As of Python 3.8, python C extensions modules should not link to libpython, unless they embed the interpreter in their code. Relevant upstream PR: https://github.com/python/cpython/pull/12946 If your package links to libpython without requiring it, it won't be possible to use the python3-debug binary with your python C extension, unless you recompile the extension against it. On Fedora Rawhide, there are at this point 144 packages linking to libpython, many of those possibly without any need for it. If your package links to libpython but it does not embed the interpreter, I would like to ask you to unlink it. Usually the fix needs to be done at the package's build system. If you are not sure if your package links to libpython, a way to figure this out is to inspect the code for the Py_Initialize and the Py_Finalize calls [0]. If the code includes those calls, no action is required from your side. If it does not, linking to libpython is not required. I might mass file bugzillas at a later date, but I wanted to provide you the heads up before that. [0] https://docs.python.org/3/c-api/init.html#initializing-and-finalizing-the...
