= Proposed System Wide Change: GCC49 = https://fedoraproject.org/wiki/Changes/GCC49 Change owner(s): Jakub Jelínek <jakub@xxxxxxxxxx > Switch GCC in Fedora 21 to 4.9.x, rebuild all packages with it. == Detailed Description == GCC 4.9.0 is currently in stage4, in prerelease state with only regression bugfixes and documentation fixes allowed. The release will happen probably in the first half of April. Marek Polacek has performed a test mass rebuild on x86_64 with gcc-4.9.0-0.*.fc21, most packages have built successfully, others have failed to rebuild also with gcc 4.8.x, for the remaining packages most of the needed changes are now tracked in [1] or, if it were bugs on the gcc side, have been fixed in the mean time. GCC 4.9.0 prereleases have so far been built as scratch packages, [2] (and similarly for ppc* and s390* secondary architectures). Other distributions have performed test mass rebuilds on other architectures (i?86, s390x, arm). == Scope == All packages should be rebuilt with the new gcc once it hits f21. * Proposal owners: Build gcc in f21, rebuild packages that have direct dependencies on exact gcc version (libtool, llvm, gcc-python-plugin). * Other developers: First few days/weeks just voluntary rebuilds using the new system gcc, if things fail, look at http://gcc.gnu.org/gcc-4.9/porting_to.html and fix bugs in packages or, if there is a gcc bug or suspected gcc bug, analyze and report. * Release engineering: Organize a mass rebuild * Policies and guidelines: No policies need to be changed --- Change Wrangler Note: Contingency Deadline is a bit vague "Before release" but with GCC revert, distribution wide coordination would be needed with high probability of slip. I'll open it for further discussion on list for FESCo/releng..
