Próbowałem uruchomić C ++ 11, po przejrzeniu różnych stron internetowych i Q / A nadal mam problemy z. Chcę używać clang z libstdc ++. W statusie clang wskazano, że jest on obsługiwany przez patch -http://clang.llvm.org/libstdc++4.7-clang11.patch. Ściągam gcc4.7 z macportów i wprowadzam odpowiednie zmiany w nagłówkach gcc4.7

Powodem, dla którego nie używam libc ++, jest zgodność ABI między libc ++ i libstdc ++, wskazana przez ten wątek:Dlaczego nie można połączyć z libc ++ w trybie c ++ 0x link tego przykładu boost :: program_options?

OK, po zakończeniu wszystkich czynności przetestowałem konfigurację za pomocą następującego kodu:

<code>#include <mutex>
#include <thread>

int main ( ) {
    std::mutex myMutext;
    return 0;
}
</code>

Oczekuję, że dołączenie powinno działać pod c ++ 11.

Oto, jak go skompilować: z GCC

<code>g++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main
</code>

Kompiluj pomyślnie

z Clangiem

<code>clang++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main
</code>

Dostaję ten błąd:

Używam wersji clang:

<code>Apple clang version 4.0 (tags/Apple/clang-418.2.41) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.3.0
Thread model: posix

czy robię coś źle? czy jest to problem z najnowszym gcc 4.7 libstc ++?
