title: How to change compiler in Xcode C++
body: <p>I've been searching for quite some time, and I can't seem to find out how to change the compiler on the latest Xcode. I am not sure what it is set at currently, but I'd like to change it to GCC if possible. Right now my homework example will not recognize ptrace.h, so I think it might have to do with the chosen compiler.</p>
