多线程在提升我应该如何编译这个

我安装了boost库。没有多线程，一切都会好起来的。我如何编译这个测试程序？多线程在提升我应该如何编译这个

#include <boost/thread/thread.hpp> 
#include <iostream> 
using namespace std; 

void hello_world() { 
    cout << "I'm new thread!" << endl; 
} 

int main(int argc, char* argv[]) {  
    boost::thread my_thread(&hello_world); 
    my_thread.join(); 

    return 0; 
}

我用：g++ -I/home/user/boost/include testc.cpp

但G ++告诉我：

您需要使用Boost线程库以及链接：

g++ -I/home/user/boost/include testc.cpp -L/home/user/boost/lib -lboost_thread

（假设库在/home/user/boost/lib。）

和“boost :: system :: generic_category（）”等符号可能来自boost_system库。 – 2012-07-13 09:11:22

谢谢你的回答。我添加：'-lboost_system'，一切正常。 'g ++ -I/home/user/boost/include testc.cpp -L/home/user/boost/lib -lboost_thread -lboost_system' – user1518451 2012-07-13 09:35:13

'g ++ -static -pthread -I/home/user/boost/include testc .cpp -L/home/user/boost/lib -lboost_thread -lboost_system' – user1518451 2012-07-13 12:03:12
