[This was previously a bug report involving -lpth and -lgc on Debian
GNU/Linux. I found out that the problem stems from -lgc dragging in
-lpthread.]
This is a simple test to show that Pth and Pthreads can't run in the
same executable on my machine. Is there a good reason why this is so?
I would have thought that Pth would happily run in a single kernel
thread.
Any advice to getting this working is greatly appreciated. I can
supply more details if you ask me for what you need.
$ cat t.c
#include <pth.h>
int
main (int argc, char **argv)
{
pth_init ();
return 0;
}
$ gcc -o t t.c -lpth -lpthread
$ gdb t
