Description Florian Weimer 2017-11-17 08:34:52 UTC
+++ This bug was initially created as a clone of Bug #1432191 +++

Description of problem:
Since the hardened by default change, gcc will sometimes fail to compile stuff if redhat-rpm-config isn't installed. This is because it now depends on the redhat-hardened wrappers shipped in redhat-rpm-config.

This problem is so bad that it's documented on

Please split out the hardening wrappers into their own package and make gcc depend on them.

Version-Release number of selected component (if applicable):

Additional info:
This also affects Fedora 24, Fedora 26, and Rawhide.

This looks like a ruby bug to me.  It extracts the build flags from the build environment.  As such, it is the responsibility of the ruby package to replicate the build environment (e.g., the rubygems package should depend on redhat-rpm-config).

GCC itself works just fine without redhat-rpm-config.

If it was just ruby, sure. But it also happens with lots of different things[1][2][3][4][5].

It's a fairly generic thing, affecting C/C++, Python, and other things that attempt to use GCC.


--- Additional comment from Jonathan Wakely on 2017-03-18 18:20:24 CET ---

It's still not a problem with GCC. Those things are passing an option to gcc telling it to use a file that is part of redhat-rpm-config, so those things should depend on redhat-rpm-config.

If I call gcc with -lcurl and haven't installed libcurl-devel it fails to find the file, but that doesn't mean gcc should depend on libcurl.

This is definitely still a problem, because I observed this when setting the CI for gsignond[1][2].

This is a bug in rubygems because it bakes toolchain compilation flags into RPM packages.  It should not do that.

Comment 1 Mamoru TASAKA 2017-11-20 06:46:44 UTC
Actually after debugging the case,

it turned out that this case is due to bug 1217376 , i.e. python2 distutils embeds this option, not gobject-introspection.
