Looks as if gcc warns on more possible errors with each newer version. Try searching for where -Werror is invoked, possibly something like find -name 'Makefile*' | xargs grep Werror and then use sed on each file (e.g. sed 's/-Werror //. Probably easiest to run find after running configure. I'm not very experienced with the current qt configure system, it's possible that -Werror might be defined elsewhere, e.g. in .mak files. Alternatively, if you know of any distro using gcc-4.7 and kde, check how they build! ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
