How can I modify the CFLAGS before emerging a package? I want to add
-g2 to the compile of libxml2 so I can step through their functions. If
I add -g2 to CFLAGS in make.conf it will do it for all packages which is
not what I want.


Thanks,

Dave

Same way as with USE flags, I think.

# CFLAGS="-g2" emerge libxml2

It won't be persistent (like things you put inside /etc/portage/package.{keywords,mask,unmask,use} but an idea would be:



root@machine ~ $ CFLAGS="$CFLAGS -g2" emerge whatever_package

You can use the "/etc/portage/env/category/package" to declare environment variables for specific packages...
