Question

我正在尝试运行一个简单的代码，它可以编译，但是当我尝试运行它时，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

Answer 1

线程的析构函数：

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

这就是你的情况。

在 main 中调用 oi.join();。

c++ - 无法解决 SIGABRT

c++ - Can't solve SIGABRT

gdb

sigabrt
