Compiling crack

[Bryan_6]

I'm trying to compile the crack program on HPUX 10.20 and I'm receiving the following error:

cracker.c: In function `Logger':
cracker.c:108: warning: implicit declaration of function `time'

Can anyone give me some guidance on getting this to compile successfully?

Thanks

That appears to be the same doc that comes with the crack source. Unfortunately, there was nothing in there to help.

However, I did edit the cracker.c source to comment out the SIG??? declarations, which helped the compile to complete successfully.

SIG* is defined in /usr/include/sys/signal.h

It looks like your code is missing a
#include
