Installing Sqlite3 Gem Error

Question

I'm getting the following error when trying to install the Sqlite3 gem on OS X Lion with XCode 4.2 installed:

$ gem install sqlite3
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:
    ERROR: Failed to build gem native extension.

Would linking to /usr/bin/llvm-gcc-4.2 be the only fix (seems a little hack-y)? Or am I missing something?

Answer 1

It would appear that XCode 4.2 doesn't install gcc-4.2, but instead llvm-gcc-4.2. Clearly Apple feels that LLVM is mature enough to superseed GCC.

There are two options I can think of. You should be able to choose either and be OK.

1. Use this GCC installer.

2. Symlink LLVM using sudo ln -s /usr/bin/llvm-gcc-4.2 /usr/bin/gcc-4.2.
