present llvm:15/15 ebuild fails to build with gcc:15 due to missing cstdint includes Reproducible: Always Steps to Reproduce: select current gcc 15 as active compiler (presently sys-devel/gcc-15.0.0_pre20240908) emerge -va1 sys-devel/llvm:15 Actual Results: multiple failure spots that hint at needing to include cstint example: /var/tmp/portage/sys-devel/llvm-15.0.7-r6/work/llvm/include/llvm/ADT/SmallVector.h:88:69: error: ‘uint64_t’ was not declared in this scope 88 | typename std::conditional<sizeof(T) < 4 && sizeof(void *) >= 8, uint64_t, | ^~~~~~~~ /var/tmp/portage/sys-devel/llvm-15.0.7-r6/work/llvm/include/llvm/ADT/SmallVector.h:29:1: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’ 28 | #include <memory> +++ |+#include <cstdint> 29 | #include <new> will attach the first build failure log (ones from other missing spots were similar) will attach working patch that allows it to successfully compile

Created attachment 902934 [details, diff] sys-devel/llvm: Bump llvm:15 patchset for more gcc-15 fixes I'm sorry, I've just noticed that we already had a patch pending that didn't make it to the ebuild. Since this patch adds the include to a different file, could you please test if it fixes the issue for you? Perhaps cstdint gets implicitly included everywhere else. I'm attaching a patch that bumps the patchset to -r7.
mgorny, After removing my local patch, and applied the patch use to use LLVM_PATCHSET=${PV/_/-}-r7 Successfully built sys-devel/llvm-15.0.7-r6 with it applied.
