Detect compiler with #ifdef

Question

I\'m trying to build a small code that works across multiple platforms and compilers. I use assertions, most of which can be turned off, but when compiling with PGI\'s

Answer 1

Have you looked at the boost headers? Supposing they support PGI, they will have found a way to detect it. You could use that. I would start to search somewhere in boost/config.

Answer 2

You could try this to see what macros are predefined by the compiler:

pgcc -dM

Maybe that will reveal a suitable macro you can use.

Answer 3

Take a look at the Pre-defined C/C++ Compiler Macros project on Sourceforge.

PGI's compiler has a __PGI macro.

Also, take a look at libnuwen's compiler.hh header for a decent way to 'normalize' compiler versioning macros.
