    Unhappy C threads

    I was trying to implement threads in my C code and this is the first time I did this I used

    /*mod edit: Dead links removed. Please post your own code, not links, especially ones which lead nowhere ~ kenfitlike*/

    as reference

    but when I compile I get the error

    :/home/shahan/engine_driver.c:43: undefined reference to `pthread_detach'
    collect2: ld returned 1 exit status
    make: *** [engine] Error 1

    I will include the code where I create the thread

    can some one help me on this

    Without looking at your code, I would say you are missing a library in your linker command line arguments.
    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    From http://www.cplusplus.com/ref/cstdlib/exit.html:
    Terminate calling process.
    So it would terminate other threads, too.
