[Python-Dev] Dropping AC_C_CHAR_UNSIGNED from configure.ac?
Hello Pythonistas. In (development branch of) Fedora, we have juts upgraded to GCC 12. It seems that the presence of AC_C_CHAR_UNSIGNED in Python's autotools files (configure.ac?) is causing the __CHAR_UNSIGNED__ symbol to be defined in pyconfig.h and that breaks some other packages with GCC 12. The GCC maintainers told us it is a reserved symbol, see https://bugzilla.redhat.com/2043555 for details. It seems that using AC_C_CHAR_UNSIGNED is not recommended and also not required, but I must confess that I am pretty much horrified by autotools and I don't really know if we can get rid of AC_C_CHAR_UNSIGNED or not. I can test this in Fedora and I am quite sure it'll work, but I don't know the impact on all the other environments where CPython can be compiled. Is there anybody on this list who knows a reason we need to keep AC_C_CHAR_UNSIGNED around in 2022? Or is it safe to get rid of it?

I went with Google rather than Bing but here's what I found: https://gist.github.com/stroxler/ade7977ed07e27448222a468796bc467 I did check a few Bing queries, the results are mostly a bit less helpful, I get more discussions of the `type` function and fewer about type annotations. But the Real Python tutorial still shows up on the first page most of the time. ___ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/AHJCF57LISD7G7DHLSQLKDKGN6FFHT3M/ Code of Conduct: http://python.org/psf/codeofconduct/
