Re: Pre defined #defines for different cross compilers ?

Where can I get a list of the different predefines defined

For example __CYGWIN32__ is defined in the cygwin
version of gcc. __unix__ under at least the linux version og
gcc.


For each installed cross or native gcc, try this:

gcc -dM -E - </dev/null

This will print out all the built in cpp predefines based upon the arguments given.
It is also handy for adding CPU model related flags and seeing what predefines
you get.
