If you mean that rawhide now uses gcc 15, then yes (not building 3.14 is of course not on purpose, but it might be that it is not valid C23 or various other reasons). > Unfortunately the builds also started to fail, so I'm trying to pin point > the issue.

Fedora has been using gcc prereleases as system compilers usually since mid to late January for many years (don't remember exactly, decade and half or more). > I look at the documentation linked > in the Fedora Change, but https://gcc.gnu.org/gcc-15/porting_to.html says: > "Note: GCC 15 has not been released yet, so this document is a > work-in-progress." Yes, we plan to add details there really soon, David Malcolm has performed a mass prebuild of Fedora with ~ a month old version of gcc over Christmas and its analysis is being finalized now. I guess for packagers the most important change is that gcc switched in C to -std=gnu23 by default (compared to -std=gnu17 default in gcc 14 and some earlier releases), which means that e.g. void foo (); changed behavior from function with unspecified parameters returning void to function with no parameters returning void (like in C++), bool, false, true are keywords, there is [[]] attribute support etc. David's notes are in https://fedoraproject.org/wiki/F42-gcc-15-mass-prebuild#Automated_classification I think, e.g. gentoo notes are in https://wiki.gentoo.org/wiki/Modern_C_porting#Fixes_.28C23.29 Jakub -- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
