I have not done a fresh build since 7.9, so I haven't tried a newer glib - but it is worrying if it expect 'python' to be v3 : the v3 name has been python3 for several releases. The switch is to tell configure to use python3 rather than python2, so it is supposed to be able to build without 3 (and I hope that is still true). ĸen -- This email was written using 100% recycled letters. -- http://lists.linuxfromscratch.org/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
