Missing buildrequire libpsm2-devel
Last modified: 2017-03-22 12:50:51 EDT
Description of problem: yum-buildep fails to install all build requires. Version-Release number of selected component (if applicable): openmpi-1.10.0-10.el7 Steps to Reproduce: 1. yum-builddep openmpi-1.10.0-10.el7.src.rpm Loaded plugins: product-id Enabling rhel-source repository Enabling rhel-opt-source repository Getting requirements for openmpi-1.10.0-10.el7.src --> Already installed : gcc-gfortran-4.8.5-4.el7.x86_64 --> Already installed : 1:valgrind-devel-3.10.0-16.el7.x86_64 --> Already installed : libibverbs-devel-1.1.8-8.el7.x86_64 --> Already installed : opensm-devel-3.3.19-1.el7.x86_64 --> Already installed : librdmacm-devel-1.0.21-1.el7.x86_64 --> Already installed : hwloc-devel-1.7-5.el7.x86_64 --> Already installed : python-2.7.5-34.el7.x86_64 --> Already installed : libtool-ltdl-devel-2.4.2-20.el7.x86_64 --> Already installed : libesmtp-devel-1.0.6-7.el7.x86_64 --> Already installed : libfabric-devel-1.1.0-2.el7.x86_64 No uninstalled build requires 2. su test -c 'rpmbuild --rebuild openmpi-1.10.0-10.el7.src.rpm*'' Actual results: warning: user mockbuild does not exist - using root <snip> error: Failed build dependencies: libpsm2-devel is needed by openmpi-1.10.0-10.el7.x86_64 Expected results: all build requires are installed and package is successfully rebuilded. Additional info: Not sure if a spec issue or yum-buildep bug...
The libpsm2 source package surely generates the libpsm2-devel binary package. Need to check if it appears in the expected repositories...
libpsm2-devel is in the optional channel, but that was not the issue. The problem is due to a known limitation in how a src.rpm can express BuildRequires that are arch-specific. openmpi.spec has: %ifarch x86_64 BuildRequires: infinipath-psm-devel libpsm2-devel %endif If Koji/Brew chooses to create the src.rpm on an x86_64 host, the resulting src.rpm will have libpsm2-devel listed among its Requires. Otherwise it will not. For instance: # rpm -qip openmpi-1.10.3-3.el7.src.rpm | grep Arch Architecture: ppc This src.srpm was created on a ppc machine. And indeed there is no mention of libpsm2-devel in its Requires: # rpm -qRp openmpi-1.10.3-3.el7.src.rpm | grep psm # If however I first install the src.rpm, and recreate it from the spec file on my local x86_64 host, it will have the Requires recorded: # rpm -i openmpi-1.10.3-3.el7.src.rpm ... # cd ~/rpmbuild/SPECS # rpmbuild -bs openmpi.spec Wrote: /root/rpmbuild/SRPMS/openmpi-1.10.3-3.el7.src.rpm # rpm -qRp ../SRPMS/openmpi-1.10.3-3.el7.src.rpm | grep psm infinipath-psm-devel libpsm2-devel For an older discussion about this topic with RPM developers, see bug 948709.
