Created attachment 530935 [details]

Description of problem:
Any compilation with clang fails in the linker phase because of missing -L/usr/lib/gcc/x86_64-redhat-linux/4.6.2 .

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

How reproducible:

Steps to Reproduce:
1. echo 'int main(void) {return 0;}' > testcase.c
2. clang testcase.c
Actual results:
/usr/bin/ld: cannot find crtbegin.o: No such file or directory
/usr/bin/ld: cannot find -lgcc
/usr/bin/ld: cannot find -lgcc_s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Expected results:
Compilation finishes and a.out is created.

Comment 3 David Tardon 2011-11-28 03:20:16 EST
Note: given that llvm needs exact version of gcc, it should use versioned require for it. This way this kind of problem would be detected by broken dependencies.

I've just been hit by this bug. Failed to link anything compiled with clang.

Would it be worthwhile submitting an update with just this fix?
Comment 5 Julian Stecklina 2011-12-12 16:28:22 EST
By all means, yes. It's not that it is useful for anything right now.
Comment 6 Peter TB Brett 2011-12-12 17:06:27 EST
I thought I'd try out clang.  So I installed it with yum, like I install all the other packages I want to try out.  I don't think it's unreasonable that when I install a compiler package, I get a compiler that works. :-P

I'm slightly surprised and disappointed that a bug that makes a package *completely useless* has been sitting around untouched for a month and a half!

Comment 9 john.haxby@oracle.com 2012-02-01 08:09:36 EST
The fix is dead simple: Add "4.6.2" to the list of gcc versions in clang-2.9-add_gcc_vers.patch (part of the SRPM) and rebuild.   You might want to increment the release number in the .spec file so that the RPMs will be an upgrade.
Comment 10 john.haxby@oracle.com 2012-02-01 08:11:37 EST
I meant to add that since the patch is so simple, why can't this just be pushed out?
Comment 11 Michel Alexandre Salim 2012-02-01 20:53:49 EST
Apologies; was trying to fix another unrelated problem, but of course as you pointed out the supported compiler list needs updating. Thankfully this goes away with 3.0 (unfortunately we have bigger problems there with GCC 4.7)
