GCC 15 mass prebuild
These are notes to myself on my attempts to use mass-prebuilder to test GCC 15 in Fedora in December 2024
Current status
- Timeout building GCC in copr, so using one of Jakub's scratch builds, turned into repos here.
- Currently having quota issues uploading the repos, so only testing aarch64 for now
- Disabling annobin in redhat-rpm-config in the copr for now due to https://sourceware.org/bugzilla/show_bug.cgi?id=32429
libtool can't be installed
Problem: cannot install both gcc-15.0.0-0.2.fc42.aarch64 from https_dmalcolm_fedorapeople_org_gcc_gcc_15_mass_prebuild_arch and gcc-14.2.1-6.fc42.aarch64 from fedora - package libtool-2.5.4-1.fc42.aarch64 from fedora requires gcc(major) = 14, but none of the providers can be installed - cannot install the best candidate for the job - conflicting requests You can try to add to command line: --no-best to not limit the transaction to the best candidates Copr build error: Build failed
Function prototypes with empty params change from implicit "int" to "void"
GCC 15 defaults to C23, in which I believe that
extern int foo();
in a decl now means
extern int foo(void);
rather than:
extern int foo(int)
"void" rather than implicit "int"; TODO: get chapter-and-verse for this
