C++ 增压条件变量SIGABRT

以下是我的主要节目

#include<csignal>
#include<iostream>
#include<string>

void signalHandler(int signum)
{
  std::cout<<"SigNum"<<signum;

  exit(signum);
}

int main()
{
  signal(SIGABRT, signalHandler);
  signal(SIGINT, signalHandler);
  signal(SIGSEGV, signalHandler);

  Context context;

  //Mutiple threads set up and working with cclContext member functions
  //and joined to main thread

  raise(SIGINT);
}

std:：COUT代码不可编译。在发出sigint信号之前是否连接所有线程？是的，它们都已连接到主线程
class Context

    std::queue<Data> _queue;
    mutable boost::mutex _mutex;

  public:
