Hi all I'm trying to compile gcc for an avr architecture. I've used standard directories in ./configure (--prefix=/usr etc). The only except is --exec-prefix which I set to /usr/lib so gcc looks for avr related files in /usr/lib/avr/. That all is fine except includes. gcc keeps using default set of includes (with nonexisting /usr/avr/include). I wish it was looking for .h files in /usr/lib/avr/includes (and only there! as /usr/include & co dirs are inappropriate for avr architecture). How can I simply achieve that? best regards -- Michał Walenciak gmail.com kicer86 http://kicer.sileman.net.pl gg: 3729519
