Shortly (Martin is in Cc to confirm): 1) Make a module: $ fedpkg clone cmake3 $ fedpkg request-repo --namespace modules --exception cmake3-latest $ fedpkg request-branch --namespace modules --repo cmake3-latest epel8 2) Writing a `modulemd` file based on this example [1]: [1] https://docs.fedoraproject.org/en-US/modularity/making-modules/defining-modules/ 3) Build the module: $ fedpkg module-build On 14/05/20 17:51, Petr Pisar wrote: > On Thu, May 14, 2020 at 06:46:29AM -0500, Richard Shaw wrote: >> So this happened: >> >> https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2020-ad02b27ee3 >> https://bugzilla.redhat.com/show_bug.cgi?id=1830748 >> >> TLDR; So we need an updated version of CMake in EPEL 8 but RHEL/CentOS >> already provide a "3" version.
