I'm trying to use pthreads under FreeBSD 2.2.1. As instructed in man
pthread I have:
cd /usr/src/lib/libc_r
make depend && make all && make install
Then I built the tiny source shown below with this incantation:
threadtest:
g++ -o threadtest threadtest.cxx /usr/lib/libc_r.a
That's fine (well it doesn't complain). But when I run the program it just
kind of hangs there, but is way up the list if I run top. Can anyone tell
me what I've missed?
Here's the source to threadtest.cxx:
#include <iostream.h>
#include <pthread.h>
void *runme(void *);
int main()
{
pthread_t thread;
pthread_attr_t *attr = 0;
cout << "hello" << endl;
pthread_create(&thread, attr, runme, "hello thread");
cout << "done" << endl;
}
void *runme(void *arg)
{
cout << "hello, from thread" << endl;
}
If you can help, please mailto:peter.marks@pobox.com
Many thanks.
