Wenn Sie C ++ 11 mit stdlibc ++ 4.7 aktivieren, klammern Sie Fehler aus, während gcc einwandfrei kompiliert
Ich habe versucht, C ++ 11 zum Laufen zu bringen, nachdem ich verschiedene Websites und Fragen / Antworten durchsucht habe, habe ich immer noch Probleme mit. Ich möchte clang mit libstdc ++ verwenden. Es wird im Clang-Status angezeigt, dass es mit Patch unterstützt wird -http://clang.llvm.org/libstdc++4.7-clang11.patch. Ich habe die gcc4.7 von macports heruntergeladen und entsprechende Änderungen in den Headern für gcc4.7 vorgenommen
Der Grund, warum ich libc ++ nicht benutze, ist die ABI-Kompatibilität zwischen libc ++ und libstdc ++, die durch diesen Thread angezeigt wird:Warum kann nicht mit libc ++ im c ++ 0x-Modus geklingelt werden, um dieses Beispiel für boost :: program_options zu verknüpfen?
OK, nachdem alles fertig ist, habe ich mein Setup mit dem folgenden Code getestet:
<code>#include <mutex> #include <thread> int main ( ) { std::mutex myMutext; return 0; } </code>
Ich erwarte, dass include unter c ++ 11 funktionieren sollte.
Also hier ist, wie ich es kompiliere: mit GCC
<code>g++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main </code>
Kompilieren Sie erfolgreich
mit Clang
<code>clang++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main </code>
Ich erhalte diesen Fehler:

Ich benutze die Clang-Version:
<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 </code>
Mache ich etwas falsch? oder ist das ein klirrendes Problem mit der neuesten gcc 4.7 libstc ++?
