Compiler identification macro?

[Carl Ribbegaardh]

Is there any known list of compiler identification macros?
I'm using VS 2003, g++ on windows, sun's cc and g++ on solaris. Is it
possible to identify the compiler using macros?
I'm aware of WIN32 being defined, but that's defined on mingw g++ in windows
too.
Is it called compiler identification macros or is there another term I
should search for?

Thanks!

It's possible, but exactly what macros you look for differs from system
to system. See, for example:

GCC: Common Predefined Macros (macros defined in every port of GCC)
http://gcc.gnu.org/onlinedocs/gcc-3....fined%20Macros

GCC: System-specific Predefined Macros (how to find system-specific GCC
macros)
http://gcc.gnu.org/onlinedocs/gcc-3....fined%20Macros

Microsoft: Predefined Macros
http://msdn.microsoft.com/library/de...ned_macros.asp

I usually look for _MSC_VER to identify Microsoft compilers.

Since the answer to your question differs from system to system, you'll
have better luck seeking answers on newsgroups devoted to your
platform/compiler (assuming you can't find the answers in the
documentation).

These should be in the specific documentation for each compiler you are
using. For Digital Mars C++, the correct way to identify it is:

#ifdef __DMC__
// You're running the Digital Mars C++ compiler
#endif

Do not use WIN32, as that specifies the target operating system, and many
diverse compilers target WIN32.

Man, I sure wish I'd have known about that page when I was struggling with
this very issue when working on InitUtil. But that was before I'd begun
dabbling in newsgroups, and it never occurred to me I could just ask the
question! So great answer, and equally great question ;-)
