c++ - 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 pgicpp using -mp for OpenMP support, it automatically uses the --no_exceptions option: everywhere in my code with a "throw" statement generates a fatal compiler error. ("support for exception handling is disabled")

Is there a defined macro I can test to hide the throw statements on PGI? I usually work with gcc, which has GCC_VERSION and the like. I can't find any documentation describing these macros in PGI.

Answer 1

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.
