Cross compiling on XCode and Linux?

Question

I developed a fairly large application that was HW on my Mac with Xcode(5.1.1). All of the code runs perfectly and does what it suppose to do. However, when I recompile the same code on my University linux servers which has gcc 4.8.3 uncountable number of errors show up. The source code files were uploaded to the server using pscp command so there was not any form of modification involved. My question is: Is there a way to do a "compatibility mode" on Xcode so that I can try to fix any compatibility issues before uploading to University servers ?

EDIT: Some errors are:

Actually, I'm going to expand my comment into an answer.

The comment: it looks like GCC isn't building as C++11, whereas Xcode (LLVM, presumably) is. Eg see the claim that nullptr is undefined.

To force LLVM to compile as though an old fashioned C++ compiler in Xcode, open your project settings, navigate to this one:

... and select C++98.
