             Bug #: 14254
           Summary: llvm-config --libfiles lists libraries which don't
                    appear to exist.
           Product: tools
           Version: 3.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvm-config
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: terrywallwork at netscape.net

I recently built llvm 3.1 final, on Fedora 17 box 32 bit Intel box, using the
following configure options:

${SVNROOTDIRLLVMCOLLECTION}/llvm/configure --enable-optimized

This all worked well (as far as I can tell), install seems to have gone
correctly as well.  But when I then try to build an application that uses LLVM
(Blender in my case for OSL).  I get linking  errors about libraries not
existing.  I checked with llvm-config --libfiles which libraries llvm was
saying it needed to be successfully linked and it seems to list libraries that
don't seem to exist in llvm lib directory.  

In my case:


To get it to work I ended up intercepting calls to llvm-config and filtering
out these libraries so Blender would compile.  Once it did compile Blender OSL
works fine.

I know this is not the correct way to do things but I am not a hard core
programmer so doing it the correct way is beyond me.

I posted here because i am not sure if this is the same bug as this one:


Apologies if this is simply me not knowing how to configure LLVM correctly.

If you need any more information please let me know.
