win7下g++ std=c++11特性测试

1 g++编译器的选择

    有多个版本的C++编译器，包括：mingw，tdm-mingw等，但版本相对更新慢或者未提供openmp、thread库。

    经测试，选择http://code.google.com/p/mingw-builds/下的编译器，下载链接：http://mingw-builds.googlecode.com/files/x86_64-mingw32-gcc-4.7.0-release-c%2Cc%2B%2B%2Cfortran-sjlj.zip。

    解压缩到d:下。

2 测试程序

#include <thread>
#include <iostream>
#include <vector>

void hello(){
    std::cout << "Hello from thread " << std::this_thread::get_id() << std::endl;
}

int main(){
    std::vector<std::thread> threads;

    for(int i = 0; i < 5; ++i){
        threads.push_back(std::thread(hello));
    }
	
	for(auto& thread : threads){
        thread.join();
    }

    return 0;	
}

3 编译

g++ -std=c++11 test.cpp

 

4 结果

Hello from thread Hello from thread 6Hello from thread 5Hello from thread 3

2Hello from thread
4

测试通过!
