[c++] How to Detect if I'm Compiling Code with a particular Visual Studio version?

Is there any way to know if I'm compiling under a specific Microsoft Visual Studio version?

By using the _MSC_VER macro.

In visual studio, go to help | about and look at the version of Visual Studio that you're using to compile your app.

Yep _MSC_VER is the macro that'll get you the compiler version. The last number of releases of Visual C++ have been of the form <compiler-major-version>.00.<build-number>, where 00 is the minor number. So _MSC_VER will evaluate to <major-version><minor-version>.

You can use code like this:

#if (_MSC_VER == 1500)
   // ... Do VC9/Visual Studio 2008 specific stuff
#elif (_MSC_VER == 1600)
   // ... Do VC10/Visual Studio 2010 specific stuff
#elif (_MSC_VER == 1700)
   // ... Do VC11/Visual Studio 2012 specific stuff
#endif

It appears updates between successive releases of the compiler, have not modified the compiler-minor-version, so the following code is not required:

#if (_MSC_VER >= 1500 && _MSC_VER <= 1600)
   // ... Do VC9/Visual Studio 2008 specific stuff
#endif

Access to more detailed versioning information (such as compiler build number) can be found using other builtin pre-processor variables here.

In visual studio, go to help | about and look at the version of Visual Studio that you're using to compile your app.

_MSC_VER should be defined to a specific version number. You can either #ifdef on it, or you can use the actual define and do a runtime test. (If for some reason you wanted to run different code based on what compiler it was compiled with? Yeah, probably you were looking for the #ifdef. :))

As a more general answer http://sourceforge.net/p/predef/wiki/Home/ maintains a list of macros for detecting specicic compilers, operating systems, architectures, standards and more.

This is a little old but should get you started:
