Thanks, ĸen, I'd updated gcc to 5, because thought it would not be acceptable to update packages tagged gcc5 with gcc 4.9, and after your post, it seems I was wrong. Therefore, I'm going to downgrade gcc and will not be able to contribute with the tags any more. :-( -- []s, Fernando -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
