Hi, I'm having a problem with packaging crmsh for RH distros on OBS: It seems that the rpm packages end up requiring /usr/bin/python which does not exist on those distributions: https://github.com/ClusterLabs/crmsh/issues/161 I can't see any direct requirement in the spec file which would do this other than requiring python itself. I've looked at using the newer python rpm macros for crmsh, but since it's a Makefile-based build with some strange requirements, Python 2 only packaging a binary with extra files etc., it's not straight-forward. Any tips or help would be very much welcome :) The packaging is here: https://build.opensuse.org/package/show/network:ha-clustering:Stable/crmsh Cheers, Kristoffer -- // Kristoffer Grönlund // kgronlund@suse.com -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org

You get automatic requirements on shebang interpreters, i.e., what is listed after "#!" at start of your script. We're actually moving away from using /usr/bin/python. Would it help if you changed it to /usr/bin/python2 ? regards m. -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org

For what it's worth, we're moving away from /usr/bin/python in Fedora as well. We recommend using /usr/bin/python2 or /usr/bin/python3 for the version of python it should be used with. -- 真実はいつも一つ！/ Always, there's only one truth! -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org

Thank you, your recommendations seems to have put me on the right track. I managed to clean up the binary requirements, but something weird is happening when I change the shebang to /usr/bin/python2: The rpm ends up still depending on /usr/bin/python. Could it be because /usr/bin/python2 is a symlink to /usr/bin/python in the build environment or something like that? Cheers, Kristoffer

Maybe. At least in RHEL/CentOS 7, /usr/bin/python is a symlink to /usr/bin/python2, which is a symlink to /usr/bin/python2.7, so I doubt it. You may have something somewhere still declaring "/usr/bin/python" or "/usr/bin/env python" as a shebang. Something is wrong if it's generating a dependency of /bin/python, though. That means something is specifically setting "/bin/python" as a shebang. -- 真実はいつも一つ！/ Always, there's only one truth! -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org

I could define /usr/bin/python to a specific package given that there is no definition which exact python version is to be used in RedHat (from what I read here).

CentOS 7 and RHEL 7. If I build the package locally for openSUSE, I don't get any dependency on /bin/python, but when it builds through the OBS, it still gets in there. I'm rewriting all the shebangs to /usr/bin/python now which fixes it, but there were none referring to /bin/python before: It must be coming from calling "/usr/bin/env python". However, rewriting to /usr/bin/python2 doesn't work as there's still a dependency on /usr/bin/python getting in there somehow. :/ Cheers, Kristoffer
