Question

I tried to test an example of C++11 threads in Eclipse. But I got this message when running the program:

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

My system: ubuntu + gcc 4.7

Program:

#include <iostream>
#include <thread>

void worker()
{
    std::cout << "hello from worker" << std::endl;
}

int main(int argc, char **argv)
{
    std::thread t(worker);
    t.join();
}

…and yes, I put -std=c++11 and -pthread inside C/C++ Build -> Settings -> Tool Settings -> Cross G++ Compiler -> Miscellaneous -> Other Flags.

Any comments?

Answer 1

The problem was solved by the comment of Jonathan Wakely.

I added -pthread to C/C++ Build -> Settings -> Tool Settings -> Cross G++ **Linker** -> Miscellaneous -> Other Flags and the program worked correctly.

Thank you Jonathan.
