http://nathancoulson.com/proj_lfs.php I did some path modifications to ld-library.so.2 and ld-library-x86_64.so.2 in gcc at compiletime by modifiying gcc/config/i386/linux64.h. Not sure how appliable that is to your situation (and I wanted to update that page, but away from home at the moment). -- Nathan Coulson (conathan) ------ Location: British Columbia, Canada Timezone: PST (-8) Webpage: http://www.nathancoulson.com -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
