{{Compiler}}[[Category:Encyclopedia]]The '''GNU Compiler Collection''', or '''GCC''', is a multi-language compiler supporting multiple target architectures. As of version 4.1, the main branch includes support for [[Ada]], [[C]], [[C++]], [[Fortran]], [[Java]], [[Objective-C]], and [[Objective-C++]]. Support for other languages is possible through the creation of a compiler front-end.

==Basic Usage==

Any of GCC's supported languages may be compiled through the simple command-line construct:

gcc (source-file)

However, some languages depend on the [[link time|linking]] of libraries, such as C++'s [[Standard Template Library]], to reach their full potential. In GCC, one way to include the STL is to change the way the compiler is called:

g++ (source-file)

In the above two examples, GCC will produce a binary file named a.out, barring any [[compile time|compile-time]] errors. This is the executable form of the code compiled. If it is preferable to have a binary of a different name, and it usually is, one can use the -o command-line option:

gcc (source-file) -o mybinary


g++ (source-file) -o mybinary

These example behaves the same as their sibling examples, with the exception that they create a binary named mybinary instead of a.out.
