编译boost :: program_options的示例代码:http://svn.boost.org/svn/boost/trunk/libs/program_options/example/first.cpp

...在MacOS Lion(10.7.2)上,使用随MacPorts安装的boost-1.48.0:

$ clang++ -v

我正在尝试使用clang++冲突的命名空间来编译我的C++代码,但不断收到此错误.我的main.cpp文件是一个简单的Hello World程序(用于调试).

我有一种感觉问题是我在我的集​​群上编译的GCC或clang版本.关于如何追踪这个问题的任何想法？或者排除故障的步骤？

[aebrenne@hpc src]$ gcc -v

简单的程序就像这样

#include <iostream>       // std::cout
#include <thread>         // std::thread
#include <mutex>          // std::mutex

std::mutex mtx;           // mutex for critical section

int main ()
{
     return 0;
}

尝试以下编译

$ /usr/local/Cellar/gcc46/4.6.4/bin/g++-4.6 -std=gnu++0x -I/usr/local/Cellar/gcc46/4.6.4/gcc/include/c++ -L/usr/local/Cellar/gcc46/4.6.4/gcc/lib temp_mutex.cpp 
temp_mutex.cpp:6:1: error: 'mutex' in namespace 'std' does not name a type

顺便说一句,我在Mac上编译.
