He estado tratando de hacer que C++ 11 funcione, después de navegar por diferentes sitios web y Q/A, todavía estoy teniendo problemas. Quiero usar clang con libstdC++. Está indicado en el estado de clang que es compatible con el parche - http://clang.llvm.org/libstdc++4.7-clang11.patch. Descargo el gcc4.7 de macports e hizo cambios en las cabeceras correspondiente para gcc4.7Al habilitar C++ 11 con stdlibC++ 4.7, error de clang, mientras que gcc compila bien
La razón por la que yo no tenga usos libC++ se debe a compatibilidades entre ABI libC++ y libstdC++, indicados por este tema: Why can't clang with libc++ in c++0x mode link this boost::program_options example?
bien, después de todo está hecho, he probado mi configuración con el siguiente código:
#include <mutex>
#include <thread>
int main () {
std::mutex myMutext;
return 0;
}
estoy esperando que incluyen debería funcionar en C++ 11.
Así que aquí es cómo puedo compilar con: con GCC
g++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main
compilar correctamente
con Clang
clang++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main
estoy recibiendo este error:
@work:boostTest$ clang++ -std=c++11 -I/opt/local/include/gcc47/c++ -L/opt/local/lib/gcc47 main.cpp -o main

estoy usando la versión ruido metálico:
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
¿Estoy haciendo algo mal? o es este un problema de clang con la última versión de gcc 4.7 libstC++?
Usted está explícitamente '-I'-ing gcc-4.7 encabezados internos en una compilación' clang'; No esperaría que esto funcione con sensatez. – geekosaur
si hago esto: también veo error. @work: boostTest $ clang ++ -std = C++ 11 -L/opt/local/lib/gcc47 main.cpp -o principal main.cpp: 1: 10: error fatal: archivo 'mutex' no encontrado # include 1 error generado. –
¿Ha intentado pasar -std = C++ 11 -stdlib = libstdC++ –
