I did some debugging, and watched how the process was getting launched, and I've managed to get it to load! The problem was that COFF files expect to be mapped into memory at address 0, something that processes are no longer allowed to do. Run "sysctl security.bsd.map_at_zero=1” or add “security.bsd.map_at_zero=1“ to /etc/sysctl.conf and you should have it working. We probably should either make an exception for COFF files to bypass this the sysctl restriction, or at least print a more helpful error than just letting the process segfault because it didn’t get mapped where it was supposed to go. — Kevin On Oct 23, 2013, at 8:58 PM, Puppet Master <pmaster@mindslayer.net> wrote: > Hello, > > A couple of years ago I posted a message on the forums, regarding getting FoxPro (for SCO Unix) working on FreeBSD.
