Hi, I am trying to rebuild espresso to adapt to the recent cmake changes, when doing this I hit https://github.com/espressomd/espresso/issues/3396, which prevents us from compiling espresso with -lto, so I set _lto_cflags to %{nil}, which works for the build with openmpi, but gets ignored for the mpich build. I think the problem is that CMake picks up the lto flags from mpicxx and then puts them in MPI_CXX_COMPILE_OPTIONS. (Also compare mpicc -show). So I think the fix would be to strip these flags from mpicc. Sounds reasonable? The flags also contain '-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1', which effectively makes it depend on redhat-rpm-config. We had a similar issue in hdf5 a while back: https://bugzilla.redhat.com/show_bug.cgi?id=1794625 Christoph -- Christoph Junghans Web: http://www.compphys.de _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
