(In reply to comment #0) > Мне кажется, весь этот поиск в корне вреден. Тем не менее, так устроен clang... Его придётся пересобирать даже с минорными релизами gcc. Ну, или захакать. Современные версии clang (>=3.4) научились в итоге всех этих вредных проверок всё же находить разные версии нашего gcc -- лишние пересборки теперь не нужны и clang теперь не привязан к конкретной версии gcc, ему подойдёт любая. |
