Are you sure it takes longer ? Most packages default their CFLAGS, CXXFLAGS to '-O2 -g' : using -O3 is *expected* to take longer. To be clear, don't set CFLAGS, CXXFLAGS if you want to avoid problematic optimisations, just let the packages use their own defaults. Building with "CFLAGS= " and the same for CXXFLAGS will turn off all optimisations (if a package accepts that from its environment), but for e.g. gcc I *would* expect the resulting compilers to be *slow*. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
