使用shared_ptr和glutInit会导致分段错误

Question

Having asked this before I tried out a lot of things and found out that the problem has to do with glutInit. Take the following code examples: main.cpp

#include <iostream>
#include <memory>
#include<GL/glut.h>
using namespace std;
int main(int argcp, char **argv)
{
    shared_ptr<double> abc;
    glutInit(&argcp,argv);
    cout<<"Hello!"<<endl;
    return 0;
}

compiled with:

g++ -std=c++11 -g -Wall -o appx main.cpp -lGL -lGLU -lglut

cause the executable to instantly crash (no "Hello!" output) with segfault using g++ 5.2.1, ubuntu 15.10

Just commenting out the line

shared_ptr<double> abc;

will fix the crash.

Since i want to use shared_ptr and glut in a project I would like to know how this can be fixed or what causes the crash.

Edit 1: GDB trace:

Answer 1

As posted in the comments the problem was similar to the problem posted here .

The solution is adding:

 -lpthread

to the compiler flags! Thanks a lot!
