I have this built and sitting waiting on the boost rebuild to be done before it is uploaded (as I do not want to tie the boost rebuild to the toolchain update). Here are the changes: gcc-4.8.0-1 - major upstream update (http://gcc.gnu.org/gcc-4.8/changes.html) - It looks like Fedora Rawhide is already built with this so should be fairly smooth...\ - ppl dependency is gone (and will be dropped from repos - or at least from [core]) linux-api-headers-3.8.4-1 - update (from 3.7 series) binutils-2.23.2-1 - minor upstream update glibc-2.17-4 - plain rebuild libtool-2.4.2-8 - plain rebuild If everyone could lend a hand in finishing the boost rebuild, the would be much appreciated!
