c++ - 无法解决 SIGABRT

Question

我试图运行一个简单的代码，它编译但当我尝试运行它时我得到(核心转储)错误。于是用gdb查看错误是什么。

代码:

#include <thread>
#include <iostream>
#include <stdio.h>


void gerar()
{
    printf("works\n");
}

int main()
{
    std::thread oi(gerar);
    printf("oi");

    return 0;
}

g++ 行:

g++ -c teste.cpp -pthread -std=c++11  
g++ teste.o -o teste -pthread -std=c++11

线程的析构函数:

If *this has an associated thread (joinable() == true), std::terminate() is called.

这是你的情况。

在 main 中调用 oi.join();。
