Platform #defines

[Skorche]

Does anyone know where there is a table for symbols defined for different platforms? I've had some very inconclusive google runs.

I really just need the ones for OSX, Windows, and Linux.

__APPLE__
_WIN32

Ah, thank you.

Where would you find out what other kinds of symbols are defined at compile time though? I looked everywhere I could think of and googled everything I could think of and couldn't find anything.

Keith showed me this handy little trick a while ago. Give it a try:

touch foo.h && gcc -v -E -dM foo.h | less

You might be interested in the POSH (Portable Open Source Header) library, which abstracts very basic platform differences.

Portability issues including using POSH are discussed in Brian Hook's new book Writing Portable Code.

Disclaimer: these items are on I am hoping to dig into at some point, but I've not read the book nor used the library.

...and I'm just touching up the review of the book. ;)
