Hi,
I'm relatively new to this and looking to use threads. I have included
pthread.h and using the cs2005q3.2-glibc2.5-arm toolchain. The following code
won't compile, I get the following error:
main.o: In function `main':/home/ikey/bob/fred/main.c:679: undefined reference
to `pthread_create'
:/home/ikey/bob/fred/main.c:680: undefined reference to `pthread_create'
:/home/ikey/bob/fred/main.c:683: undefined reference to `pthread_join'
:/home/ikey/bob/fred/main.c:684: undefined reference to `pthread_join'
collect2: ld returned 1 exit status
make: *** [bob] Error 1
// threads
#include <pthread.h>
#include <sys/stat.h>
int main(int argc, char *argv[])
{
// thread stuff
pthread_t ctrl_t ;
pthread_t supv_t ;
...
...
...
/* Create resources and threads */
pthread_mutex_init (&mutex, NULL);
pthread_cond_init (&cond, NULL);
err = pthread_create (&ctrl_t, NULL, ctrl_loop, &r1) ;
err = pthread_create (&supv_t, NULL, supv_loop, &r2) ;
/* Wait for both threads to finish */
pthread_join (ctrl_t, NULL) ;
pthread_join (supv_t, NULL) ;
}
Have I done anything stupid? Can you not do this with N800, if not, how do you
do threads?
Ian
