I'm experimentally rebuilding rawhide with the not-yet-released GCC 15 to see if anything breaks, and to help write the porting guide. See https://fedoraproject.org/wiki/User:Dmalcolm/gcc-15 My test build with GCC 15 failed: https://copr.fedorainfracloud.org/coprs/dmalcolm/gcc-15-smoketest-3.failed/build/8476050/ whereas my test build with GCC 14 succeeded: https://copr.fedorainfracloud.org/coprs/dmalcolm/gcc-15-smoketest-3.failed.checker/build/8477597/ Looking at the failure logs https://download.copr.fedorainfracloud.org/results/dmalcolm/gcc-15-smoketest-3.failed/fedora-rawhide-x86_64/08476050-RdRand/builder-live.log.gz I see: src/librdrand-aes.c:512:5: error: conflicting types for 'keys_change'; have 'int(int)' 512 | int keys_change(int rotate) { | ^~~~~~~~~~~ In file included from src/librdrand-aes.c:33: src/./librdrand-aes.private.h:75:5: note: previous declaration of 'keys_change' with type 'int(void)' 75 | int keys_change(); | ^~~~~~~~~~~ This is probably due to GCC 15 now defaulting to -std=gnu23, whereas GCC 14 defaulted to -std=gnu17, and C23 is stricter about function prototypes than C17. It's probably fixable by fixing the function prototypes (or by manually adding -std=gnu17 to the C build flags) Reproducible: Always
Thanks for the report, Dave! I have fixed the source code and released the 2.1.6 version with the fix. https://github.com/jirka-h/RdRand/releases I have pushed the changes to rawhide - check this build https://koji.fedoraproject.org/koji/taskinfo?taskID=127753487 Could you please verify that RdRand-2.1.6-1 compiles with GCC v15? Thank you Jirka
Succeeded in the mass rebuild, thanks! https://koji.fedoraproject.org/koji/buildinfo?buildID=2616827
