Hi, due to https://fedoraproject.org/wiki/Changes/Python_Extension_Flags it is no longer correct to just call `python3 setup.py build` or `python3 setup.py build_ext` in spec without setting the proper flags (for arched builds with Python extension modules at least). That is without setting both CFLAGS **and** LDFLAGS. I've grepped the usage and skimmed trough specs, destining the following list of packages that fail to properly set both flags. I intend to fix the packages using my provenpackager rights during next week. I plan to push directly. There is no automated script, I'll do the changes by hand. I will: 1) use %py3_build if possible 2) use %set_build_flags otherwise if possible 3) add the missing CFLAGS and/or LDFLAGS variables manually otherwise If you prefer to fix your package yourself, please do (I would appreciate this). If you need more time, let me know. If you prefer a Pull Request over a direct push, let me know. The change in python3 package did not yet happen, no rebuild is needed and I will not bump release or add a changelog entry for this. I will check if the package builds and I will not introduce a new FTBFS. I will not try to fix nontrivial already existing FTBFS.
