The libraries/binaries also need to be installed into the %{_libdir}/openmpi/{bin,share,lib} hierarchy.

I need to follow up on my own post - still haven't figured out how the RPM requires are done.In the first step, I've completely stripped out my package so that it only builds a simple library (pretty much an mpi "hello world"), and an executable to call it. Wrapped them in a spec file, and these also only create a dependency onlibmpi.so.40()(64bit)For comparison, I've rebuilt libptscotch (mpich and openmpi) using sources and specs pulled from the srpm. These rpms build correctly *and* they also have the expected dependency onlibmpi.so.40()(64bit)(openmpi-x86_64)I don't understand how the rpm dependency check on the built libraries works in one case, but not in the other.The only thing I can imagine is that for the ptscotch build, it uses mpicc instead of gcc + libraries. But even so, how is that information propagate through the libraries?Any hints, even a polite "rtfm" with the name of the docs I am missing would be very welcome at this point.Thanks, /mark On 2020-10-22 13:47, Mark Olesen wrote:This will presumably also affect Fedora, but need to recheck.We are experiencing some very odd build behaviour using copr to compile for various Fedora and CentOS/RedHat versions (https://copr.fedorainfracloud.org/coprs/openfoam/openfoam).The built package on centos8 is automatically given the requirement - libmpi.so.40()(64bit) But the openmpi package actually provides - libmpi.so.40()(64bit)(openmpi-x86_64)_______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxxFedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelinesList Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
