c++11 thread --多线程编译报错问题解决办法

//test.cpp
#include 
#include 

#include 
#include 

std::mutex mMutex;

using namespace std;

static int count=0;
static int MAX=5000;
static int line=0;
static int line_count=5;

void thread1(){
    while(1){
        if(count >x;
        if(x==0){
            break;
        }
    }

    return 0;
}



在终端中执行:

 g++ -std=c++11   test.cpp  -pthread -o test.out


编译报错:

terminate called after throwing an instance of 'std::system_error'
  what():  Enable multithreading to use std::thread: Operation not permitted

在网上查阅资料测试加上-Wl,--no-as-needed 就能正常编译运行了,完整的执行指令为:
 g++ -std=c++11  -Wl,--no-as-needed  test.cpp  -pthread -o test.out
