Al habilitar C ++ 11 con stdlibc ++ 4.7, se produce un error de Clang, mientras que gcc compila bien
He estado tratando de hacer que C ++ 11 funcione, después de navegar por diferentes sitios web y Q / A, todavía tengo problemas. Quiero usar clang con libstdc ++. Se indica en el estado de clang que es compatible con el parche -http://clang.llvm.org/libstdc++4.7-clang11.patch. Descargué el gcc4.7 desde macports e hice los cambios correspondientes en los encabezados para gcc4.7
La razón por la que no uso libc ++ es porque las compatibilidades ABI entre libc ++ y libstdc ++, indicadas por este hilo:¿Por qué no se puede colgar con libc ++ en el modo c ++ 0x vincular este ejemplo de boost :: program_options?
OK, después de que todo haya terminado, probé mi configuración con el siguiente código:
<code>#include <mutex>
#include <thread>
int main ( ) {
std::mutex myMutext;
return 0;
}
</code>Espero que include debería funcionar bajo c ++ 11.
Así es como lo compilo con: con GCC
<code>g++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main </code>
Compilar exitosamente
con Clang
<code>clang++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main </code>
Estoy recibiendo este error:
<code>@work:boostTest$ clang++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main

</code>Estoy usando la versión de 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 </code>
¿Estoy haciendo algo mal? ¿O es este un problema de argot con el último gcc 4.7 libstc ++?
