Seen on Rocky Linux 8.8 with rdma-core v51.0. I suspect 8.9 shows the same issue and I know the RC for RHEL 8.10 does as well. The cmake version is 3.20.2. The linux kernel version and hardware is not relevant since this is a cmake/build issue. The hardware is also not relevant. To reproduce: 1. download an untar the v51.0 tar ball to ~ cd ~ wget https://github.com/linux-rdma/rdma-core/releases/download/v51.0/rdma-core-51.0.tar.gz tar -zxvf tar -zxvf rdma-core-51.0.tar.gz 2. create the following directories mkdir -p ~/rpmbuild/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS,OTHER} 3. copy the spec file cp cp rdma-core-51.0/redhat/rdma-core.spec ~/rpmbuild/SPECS 4. Create SOURCES tar -zcvf ~/rpmbuild/SOURCES/rdma-core-51.0.tar.gz rdma-core-51.0 5. load build dependencies ensure AppStream, BaseOS, PowerTools repos are accessible sudo dnf install -y dnf-plugins-core rpm-build cd ~/rpmbuild/SPECS sudo dnf builddep -y rdma-core.spec 6. Load an additional pythion interpreter sudo dnf install python39 6. do the build rpmbuild -ba rdma-core.spec The build gets the following errors: error: File not found: /home/mmarcini/rpmbuild/BUILDROOT/rdma-core-51.0-1.el8.x86_64/usr/lib64/python3.6/site-packages/pyverbs error: File not found: /home/mmarcini/rpmbuild/BUILDROOT/rdma-core-51.0-1.el8.x86_64/usr/share/doc/rdma-core/tests/*.py RPM build errors: File not found: /home/mmarcini/rpmbuild/BUILDROOT/rdma-core-51.0-1.el8.x86_64/usr/lib64/python3.6/site-packages/pyverbs File not found: /home/mmarcini/rpmbuild/BUILDROOT/rdma-core-51.0-1.el8.x86_64/usr/share/doc/rdma-core/tests/*.py Earlier in the build this is seen: -- Found Python: /usr/bin/python3.9 (found version "3.9.16") found components: Interpreter -- Could NOT find cython (missing: CYTHON_EXECUTABLE CYTHON_VERSION_STRING) The issue appears to have been introduced by: 1462a8737 build: Fix cmake warning cmake appears to find the 3.9 python despite having: -DPYTHON_EXECUTABLE:PATH=%{__python3} The issue will impact 8.10 because valgrind-deve/valgrind will bring in python3.11 100% of the time.
