Description Nick Bowler 2010-09-20 20:58:02 UTC

Updating clang to the latest version has caused dynamic linking problems
preventing it from running.  Firstly, attempting to run clang produces the
following error:

  % clang
  clang: error while loading shared libraries: libLLVM-2.7.so: cannot open shared object file: No such file or directory

Further inspection reveals that this library is installed in /usr/lib/llvm,
but this path is neither in /etc/ld.so.conf nor in the runpath of clang.

So I set LD_LIBRARY_PATH=/usr/lib/llvm and run clang:

  % clang
  clang: error: no input files

So far so good.  But now when we attempt to compile any C program:

  % clang -v test.c
  clang version 1.1 (branches/release_27)
  Target: x86_64-pc-linux-gnu
  Thread model: posix

  /usr/bin/clang: symbol lookup error: /usr/bin/clang: undefined symbol: LLVMInitializeMBlazeTargetInfo
  clang: error: compiler command failed with exit code 127 (use -v to see invocation)

Downgrading to clang-2.7-r2 corrects the issue.

Thank you for taking the time to report this bug.  Just to rule out any other linking issues, have you run revdep-rebuild since seeing this error?   If not, please do so.

There is no change after running revdep-rebuild.

Thanks for the report! I removed the buggy ebuild and added -r4

The rpath sed was indeed broken, and I missed the unresolved symbol part... For 2.7 clang won't use llvm shared library, I'll fix that for 2.8.
