command line options/env variables

command line options/env variables

[Andrew Pollard]

Soory to bother the list, but how do I specify CFLAGS/CXXFLAGS so that
I can bootstrap gcc with "-mpentiumpro -march=pentiumpro" (ie do a 3
stage compile of gcc - NB I can do this...) and then compile
everything else (ie libio/libstdc++) using the same CFLAGS options?

I can setenv CFLAGS and CXXFLAGS before the configure (but I'm using
gcc-2.7.2.2 to bootstrap the compiler, and hence it complains if I
specify -mpentiumpro, etc)....

If this is a FAQ, I am sorry, but I couldn't find it :-(

PS. I've just compiled up gcc/g++/g77/objc with -mpentiumpro..., I'd
just like to compile the libraries like this as well.... results will
follow for gcc/g++/g77....

Andrew.

	I normally use BOOT_CFLAGS on the make command line with one of
the bootstrap targets.
