Compiler version, name, and OS detection in C++

Question

I need to detect the OS name, compiler name, and version of the compiler with C++, as I need to change the setup for each case.

How can I do that?

Answer 1

For most compilers you can find a list of predefined macros.

• VS http://msdn.microsoft.com/en-us/library/b0084kay%28v=vs.80%29.aspx
• gcc http://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html

Answer 2

I recommend define platform in build scripts by providing -D_i386 -DENDIAN=1234 -D_linux. But if you still think another predef project is your friend:
