--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-02-13 11:17:33 UTC --- (In reply to comment #3) > --enable-concept-checks \ You probably don't want this, some of the concept checks are incompatible with C++11, you shouldn't enable them at configure time, you can still use them later with -D_GLIBCXX_CONCEPT_CHECKS > --enable-decimal-float \ > --enable-fully-dynamic-string \ > --enable-libstdcxx-debug \ > --enable-libstdcxx-time \ This implies you want to use C++11, so you probably don't want to permanently enable concept checks. > --enable-multilib \ > --enable-plugin \ > --enable-lto \ If your build fails it's usually a good idea to try *removing* options to find the smallest set that can reproduce the bug, instead you're adding more options. > --enable-static \ > --enable-shared \ > --enable-threads \ These are redundant, you're explicitly setting default behaviour. > --enable-version-specific-runtime-libs This is broken on x86_64 multilib I don't think these are the cause of your problem, I just think you'll find it easier to identify the real problem if you keep it simple instead of adding loads of unnecessary complication.
