Once I solve this problem, the really hard one begins: trying to
debug the child (gdb doesn't handle fork very well at all). I
really need to be able to step through the child, and I don't know
how I'm going to accomplish that. sigh
Someone described this earlier, but I'll try to make it a bit more
clear. In the child, do something like this:
int main(void) {
static int foo = 0;
while (foo == 0) {
sleep(1);
}
...
}
That'll cause the child to spin on startup. Attach with gdb, type 'p
(foo = 1)' at the gdb prompt, and then go from there.
Hope this helps,
Eric
