Description Petr Pisar 2015-09-24 12:51:23 UTC
I noticed that I cannot remove pkgconfig from a system because dnf reports it would remove dnf or systemd. I tracked it down to shared-mime-info-1.5-1.fc24.x86_64.rpm that run-requires /usr/bin/pkg-config. Why?

I cannot find the dependency explicitly defined by Requires:, nor grepping the binary package does reveals any pkg-config string. Only /usr/share/doc/shared-mime-info/NEWS contains `pkgconfig' word.

According to build.log, the dependency is found by rpmbuild's generators. However I don't know how to run them manually on local files to pinpoint which file is the origin.

Finally, I cannot image why shared-mime-info would need /usr/bin/pkg-config at run-time? I hope it does not and it's just a generator's fault.

I can see this mistake in Fedora 24 as well as Fedora 22.

Comment 1 Rex Dieter 2015-09-24 13:00:05 UTC
The dep is there because it includes a pkg-config file

Comment 2 Petr Pisar 2015-09-24 13:08:16 UTC
Indeed. Shouldn't the file be in a -devel sub-package?

Comment 3 Rex Dieter 2015-09-24 13:09:26 UTC
in this case no, it contains only runtime information

Comment 4 Petr Pisar 2015-09-24 13:11:53 UTC
What is it good for at runtime? The file looks void:


Name: shared-mime-info
Description: Freedesktop common MIME database
Version: 1.5

Comment 5 Rex Dieter 2015-09-24 13:18:44 UTC
It allows one to check shared-mime-info's version

Comment 6 Petr Pisar 2015-09-24 13:27:16 UTC
At run-time?

Nevertheless moving the file into a separate package allows to drop the dependency for those who do not need to check the version at run-time. Those who need the feature still must run-require pkgconfig(shared-mime-info), so the dependency tree will be completed automatically. It does not matter whether the sub-package is called -devel or something else.

Comment 7 Rex Dieter 2015-09-24 13:33:28 UTC
I don't know the full history of this issue, but... I would be against creating a -devel pkg for the sole purpose of a single pkg-config file that contains runtime only information.

So, let's back up a step, what's the use-case for wanting to be rid of a small ~100k pkgconfig ?

Comment 8 Rex Dieter 2015-09-24 13:47:11 UTC
I think we can (and should) filter the pkgconfig dep though, one intent for not having a -devel pkg was also to avoid extra dependencies (like pkgconfig).
