clang: error: unsupported option '-static-libgcc' on Mac OSX Mavericks

Question

I am trying to compile jogl from source on my Mac Mini with Mac OSX mavericks, but getting
clang: error: unsupported option \'-static-libgcc\' on Mac OSX Maveric

Answer 1

You can fix this by putting this line in your gluegen.properties file (which should be in your Users/yourname directory):

gcc.compat.compiler=clang

This tells the JOGL build system that it's using Clang. Otherwise, it thinks it's using gcc, and tries to use gcc-specific options. This fails on Mavericks because gcc is now just a link to Clang.

Answer 2

The command called gcc is not really GCC on Mavericks. It's just a copy of Clang:

$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix

That means it doesn't support GCC-only flags like -static-libgcc. Find out what part of your build system is generating that flag and get rid of it.
