preprocessor macro

When I emerge a package, how can I specify preprocessor macros to be passed to the compiler. If I was manually compiling with gcc I would specify a preprocessor macro with the -D option.

Thanks,
Jimmy.

You can pass whatever options you want to gcc:

CFLAGS="-DSOME_MACRO -fsome-flag" emerge some-package

Also, CXXFLAGS works for g++, LDFLAGS for the linker, CPPFLAGS for the C preprocessor, etc.

When emerge is run, won't the CFLAGS in make.conf override any environment variable I set? Is there a way to append to the CFLAGS in make.conf just temporarily with a command line option in emerge.
