I asked this question on StackOverflow, but it's pretty much stagnant. Sorry if this is considered a repost/double-post.

I just installed gcc 4.9 (with C11 support), and want to add it to Xcode 4.6.3's build options as a compiler option. I ran make and make install, and the packages are all there (under /usr/bin/gcc. Running gcc --version confirms that gcc 4.9 is installed rather than an older version.

When I go into an existing Xcode project's build settings, the only compiler options available are

• Apple LLVM compiler 4.2

• LLVM GCC 4.2

• Other...

Clearly, GCC 4.9 would have to be added using the "Other..." option, although I'm not sure how. I've tried inputting the path to gcc (/usr/bin/gcc), although the default value for other isn't a path at all: com.apple.compilers.llvmgcc42.

I've also tried following the instructions from the answer to this question as well, but the machine I'm on doesn't have the /Developer directory at all, since I believe Apple integrated the developer tools that required (and created) this directory into Xcode.

How do I add gcc 4.9 as a compiler option in Xcode?
