Question

I’d like to achieve something similar to interface Runnable from Java. I try to do that in that way:

class Runnable{
    public:
        void start(){
            t = std::thread(&Runnable::run, this);
        }
    protected:
        virtual void run(){
        }
};

Idea is simple. I’d like to overload run method and then start() should launch overloaded one. But… it doesn’t work.

terminate called after throwing an instance of 'std::system_error'
  what():  Operation not permitted

PS I load an instance of class, which derives from Runnable, from dynamic library with dlopen.

This error is commonly seen produced by GCC when forgetting to use -pthread at command line.
