Description Michael Schwendt 2012-02-03 12:48:53 UTC

As whether these issues are fixable, dunno. They are unusual. For example:

$ sudo yum install gedit-code-assistance
[...]
Installing:
 gedit-code-assistance    x86_64    0.1.2-1.fc16       updates            100 k
Installing for dependencies:
 clang                    x86_64    2.9-6.fc16         updates-testing    6.0 M
 llvm                     x86_64    2.9-6.fc16         updates-testing    491 k
Updating for dependencies:
 llvm-libs                x86_64    2.9-6.fc16         updates-testing    5.3 M
[...]

One doesn't get just the Clang shared lib, but with package "llvm", all LLVM tools are pulled in, too.

"llvm" is an explicit dependency in "clang" even. Why is that? The spec file ought to comment on Explicit Requires. The dependency on llvm-libs is automatic because of the shared lib (but actually llvm-libs also contains a ld.so.conf file, so that one should be an explicit dep).

* Package "clang" installs its own compiler plus headers, which belong into clang-devel instead:

# rpmls clang|grep include|wc -l
24

* The static libs for "clang" are found in llvm-devel.

* The manual for /usr/bin/tblgen (from "clang") is located in package "llvm".

Comment 1 Michel Lind 2012-02-03 14:22:44 UTC

Thanks. I need to figure out LLVM 3.0 <--> GCC 4.7 compilation problems first, at the moment, but as soon as that is fixed I'll try and reorganize the filesystem layout for F-17 and then backport those changes to F16.

Comment 2 Fedora Admin XMLRPC Client 2013-02-27 15:11:17 UTC

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Comment 3 Fedora End Of Life 2013-04-03 19:11:25 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)

Comment 4 Jan Včelák 2014-12-25 23:35:32 UTC

This report is still valid.

And I believe the explicit requirement of llvm in clang can be dropped safely.

Comment 5 Jan Kurik 2015-07-15 15:11:57 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)

Comment 6 Jan Včelák 2016-06-05 11:36:08 UTC

This problem is fixed in Fedora 24. Clang no longer pulls llvm, just llvm-libs.

We don't have resources to fix this in F23, as we completely reworked LLVM/clang packaging.
