std :: thread在linux eclipse上不起作用

我不知道为什么,但是在将我的项目中包含c ++ 11并使用std :: array<>这样的新功能之后,当我使用std :: thread时,它突然无法工作。

以下是我尝试运行的示例:

#include <iostream>
#include <string>
#include <thread>

void print_message_function(const std::string& msg);

int main()
{
    std::string message1 = "Thread 1";
    std::string message2 = "Thread 2";

    std::thread thread1(print_message_function, message1);
    std::thread thread2(print_message_function, message2);

    thread1.join();
    thread2.join();
}

void print_message_function(const std::string& msg)
{
    std::cout << msg << std::endl;
}

编译时没有错误,运行时没有错误(也没有输出..),但是当使用调试工具时,它会在此行崩溃:

std::thread thread1(print_message_function, message1);

这是崩溃时的堆栈:

Thread [1] (Suspended: Signal 'SIGSEGV' received. Description: Segmentation fault.) 
    5 _dl_fixup()  0x0000003d6920df7c   
    4 _dl_runtime_resolve()  0x0000003d69214625 
    3 std::thread::_M_start_thread()  0x0000003d762b65a7    
    2 std::thread::thread<void (&)(std::string const&), std::string&>() /usr/include/c++/4.4.4/thread:133 0x0000000000402268    
    1 main() /.../Main.cpp:12 0x0000000000401e8d    

为什么会这样?

您需要在编译命令中使用-pthread链接pthreads库。
