Enable LLVM + Clang in Xcode new project causes linking errors

I've done a complete clean uninstall of XCode and deleted the prefs and deleted complete /Developer folder and reinstalled XCode again.

I create a new Cocoa application, go over to Target, doing a "Get info" in the target and enable "C / C++ compiler version" to "LLVM compiler 1.0.2" and press Build.

I get:

ld: warning: directory '/usr/lib/gcc/i686-apple-darwin10/4.2.1/x86_64' following -L not found
ld: warning: directory '/usr/lib/gcc/i686-apple-darwin10/4.2.1/x86_64' following -L not found

ld: library not found for -lgcc
Command /Developer/usr/bin/clang failed with exit code 1

Anyone able to help me here? LLVM + GCC frontend does work though but I really would like to use Clang (LLVM compiler 1.0.2). New XCode install, new Cocoa project still have this issue.

Solution

  • I fixed it by creating two symbolic links

    /usr/lib/gcc -> /Developer/usr/lib/gcc

    and

    /usr/lib/i686-apple-darwin10 -> /Developer/usr/lib/i686-apple-darwin10/

    Thanks for answering guys.
