C: Compiler info at runtime

Question

Is there a way to print the name of the compiler and the version that was used to compile a program, something like;

printf("This is compiled with %s version %s\n", COMPILER, COMPILER_VERSION);

?

You can do this with the pre-processor:

Reference: http://predef.sourceforge.net/precomp.html

For gcc:

#if defined(__GNUC__)
# if defined(__GNUC_PATCHLEVEL__)
#  define __GNUC_VERSION__ (__GNUC__ * 10000 \
                            + __GNUC_MINOR__ * 100 \
                            + __GNUC_PATCHLEVEL__)
# else
#  define __GNUC_VERSION__ (__GNUC__ * 10000 \
                            + __GNUC_MINOR__ * 100)
# endif
#endif

For MSVC just use:

_MSC_FULL_VER

Err... What if I used microsoft's compilers? – Arafangion Jul 09 '10 at 12:05
_MSC_FULL_VER Take a look at the link. It's a reference for compiler specific pre processor defines. – Vitor Py Jul 09 '10 at 12:19

No, the way to get the name of the compiler is itself compiler-specific :-P.

gcc provides the __VERSION__ macro, though.
