When building sys-process/systemd-cron on a system with clang-17 installed using libcxx I receive the following error: clang++ -march=native -O3 -pipe -flto=thin -Wall -Wextra -fno-exceptions -Wno-psabi -std=c++20 -I /var/tmp/portage/sys-process/systemd-cron-2.2.0/work/systemd-cron-2.2.0/out/build/include /var/tmp/portage/sys-process/systemd-cron-2.2.0/work/systemd-cron-2.2.0/out/build/include/libvoreutils.hpp -o /var/tmp/portage/sys-process/systemd-cron-2.2.0/work/systemd-cron-2.2.0/out/build/include/libvoreutils.hpp.gch clang++: error: cannot specify -o when generating multiple output files make: *** [Makefile:220: /var/tmp/portage/sys-process/systemd-cron-2.2.0/work/systemd-cron-2.2.0/out/build/include/libvoreutils.hpp.gch] Error 1 Reproducible: Always Steps to Reproduce: 1. Have clang as a system compiler and use libcxx 2. Attempt to emerge systemd-cron Actual Results: Package does not compile Expected Results: Package compiles As per upstream bug report, builds fine using GCC.
Please always include the full build.log and emerge --info.
Sorry, they're attached upstream. Will add here
Created attachment 875666 [details] gcc systemd-cron
Created attachment 875667 [details] build.log (clang)
Created attachment 875668 [details] emerge --info
These logs are from manual builds, but I had the same problem with portage on v2.2.0, the issue appears to have been resolved upstream for a future release.

Sorry - need to reopen this bug as the fix doesn't work - PCH= also needs to be added to the call to emake in src_install.
