Description of problem: When building dependent kernel modules, it is helpful to have access to the headers for a given kmod. Can kmodtool be extended to provide an additional optional package containing the module headers? Version-Release number of selected component (if applicable):redhat-rpm-config-62-1.fc26 How reproducible:100% Steps to Reproduce: 1.Build kmod (example FMC) 2.Try to build kmod that links to example kmod (WhiteRabbit) 3.Headers for example kmod are not packaged anywhere Actual results: Headers for kmod are not packaged anywhere Expected results: Headers for kmod are packaged Additional info:
Adding Stanislav. Cheers, Don
kmodtool [1] is not part of redhat-rpm-config package, have you choose the right component of bugzilla ?

We have received a similar request on kmodtool. IMHO, having a given kmod to have a -devel (or header) sub-package is a wrong way of doing. Instead, I would suggest to package FMC and WhiteRabbit all along, so WhiteRabbit can use the (appropriate version of the) header of FMC from the build directory (or the source directory if relevant) than from the install system. Building kmod that way is dramatically more simple and robust. It will also fit appropriately with the build infra and not produce dependency hell when both kernel, kernel-devel, kmod-foo1-devel and kernel-bar2-devel doesn't exactly align. (not to mention kernel variant). NVIDIA kmods (nvidia-drm, nvidia-uvm, nvidia-modeset) are packaged that way on the upstream NVIDIA CUDA repository. (using akmod-nvidia for Fedora).
Closing, as there is no answer back, so I consider there is a consensus.
