I looked at the code and it's wrong for 32 bit systems. They use off_t where it needs to use uint64_t. The error cascades, but we don't use the two functions in udev anyway. >> Other thing that I dislike is shipping .la file. Those files are >> UNNECESARY in every context.

I'll do that. I'll check to see if the full path is needed. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
