Hide Forgot
+++ This bug was initially created as a clone of Bug #1512212 +++ Description of problem: The header file gdm-pam-extensions.h (/usr/include/gdm/gdm-pam-extensions.h) is a minimal header file which requires only glibc-headers and pam-devel. it provides few C macros + few definitions of structures and it does not depends on any gdm(gnome) library. This header file should be used in pam_sss which has minimal dependency. And there is a sssd ticket to separate it from daemon. https://pagure.io/SSSD/sssd/issue/2240 So installing whole gdm including all dependencies would huge complication. Please move this header file (+related pkgconfig file) to separate package which depends only on glibc and pam-devel However it is part of gdm-devel which pull many dependencies Version-Release number of selected component (if applicable): sh$ rpm -q gdm-devel gdm-devel-3.26.2.1-1.fc27 How reproducible: Deterministic Steps to Reproduce: 1. yum install 'pkgconfig(gdm-pam-extensions)' 2. rpm -q pam-devel Actual results: //318 packages installed including many X11 and wayland related packages //and pam-devel is not installed as a dependency sh$ # yum install 'pkgconfig(gdm-pam-extensions)' Last metadata expiration check: 0:12:31 ago on Sat Nov 11 15:55:58 2017.

BTW it adds 220 build dependencies for sssd + 0 runtime dependencies. Expected result is 1 additional build dependency for sssd (because sssd already depends on pam-devel and glibc-headers
So the approach we ended up with was decided on in bug 1413900 comment 8 and bug 1413900 comment 9. As you point out the current approach doesn't add any runtime dependencies, and I don't think it adds any build loops, so it's not actually, practically speaking, a real problem is it? i don't really want to create new upstream module, and add a whole new package to rhel for this. That's a lot of overhead for a file with a few convenience macros in it. If the build dependencies are actually an issue, can sssd just copy the header file in tree ? Alternatively, I guess I could create a new subpackage, %package pam-extensions Summary: macros for developing pam extensions that GDM supports Group: Development/Libraries Requires: pam-devel And not have an explict Requires: %{name}%{?_isa} = %{epoch}:%{version}-%{release} for the subpackage. I think that would eliminate the build deps, but it might make rpmdiff balk. I'm not sure. so three possibilities: 1) new module, new package, maitai process, etc 2) sssd copies header in tree 3) new subpackage I'm okay with 2 or 3, but you'll have to convince me harder for 1. Thoughts?

Exactly, we can't have the requires for that reason. Normally subpackages do have the requires to make sure the subpackage always gets upgraded in lockstep with the main package. > Sorry when it was not clear but but I meant new sub-package. okay sure. though i'm still curious why the extra build requirements are a problem. even if it were hundreds of build requirements, why would it matter (unless it creates build loops, i mean)?

A) It adds unnecessary 600+ MiB of build dependencies to sssd which causes little issues to our CI B) I do not use GNOME/GDM but I want to develop sssd with all available features C) Extra additional dependencies increase probability of problems in rawhide(but that's different BZ) And minimal devel package gdm-pam-devel(gdb-pam-extensions-devel or whatever name) is a win-win situation.
Created attachment 1352086 [details] proposed change
will push attachment 1352086 [details] if Brian is okay with this going in and gives a pm ack.
(In reply to Ray Strode [halfline] from comment #10) > Created attachment 1352086 [details] > proposed change Do you think it make sense to have suffix "-devel" in the name of new sub-package? Otherwise thank you very much. I really appreciate it.
i don't think it really matters to be honest. we have lots of prior art where -devel isn't used (atleast xorg-x11-util-macros and kernel-headers off the top of my head). But I don't care either way, so I'll throw -devel in the name when i push.
I can confirm that both the large list of dependencies is gone and pam-devel is now installed as a dependency, using the reproducer in the description.
