Failed to build json (1.6.3) with native extension after I installed Xcode 4.2

Question

Are you familiar with this error? I have no idea how to fix this:

Installing json (1.6.3) with native extensions  Gem::Installer::ExtensionBuildError: ERROR: Fai         


        

Answer 1

The makefile references /usr/bin/gcc-4.2 … I solved this by creating a symlink to the correct executable:

sudo ln -s /usr/bin/llvm-gcc-4.2 /usr/bin/gcc-4.2
