This is both a question and a reference and I am hoping that people can build upon this so that it can be reused by people with similar questions.
How can we reliably detect a particular version of a C/C++/ObjC compiler? Now I know the answer for Visual Studio and partially know the answer for Xcode.
Now for the Visual Studio compiler we have _MSC_VER which is defined with these values:
Version 1.0 800
Version 2.0 900
Version 2.x 900
Version 4.0 1000
Version 5.0 1100
Version 6.0 1200
Version 7.0 1300
Version 7.1 1310
Version 8.0 1400 (Visual Studio 2005)
Version 9.0 1500 (Visual Studio 2008)
Version 10.0 1600 (Visual Studio 2010)
Now for the Xcode compiler we have this define:
__APPLE_CC__
But the only values I've managed to find via google (Mac docs don't seem to have these values) are:
Xcode 3.0 5465
Xcode 3.1 5470
Xcode 3.1 (GCC 4.2) 5553
Xcode 3.2.3 5664 (Got this value from my own compiler)
Can anyone complete this list or provide links to a full list? And maybe we can provide information for other compilers too.
