This seems pretty clear. The linuix syscall that this program uses is not supported on FreeBSD. The linux binary compatibility is pretty good for userland binaries and so forth. But any time you get into hardware, you're stepping closer into that 10% of linux code that will not run on FreeBSD. It seems your only option would be to port that source code to FreeBSD, and use the right syscalls. Try an email to -hackers to see if anybody has any ideas on that. Personally given how cheap a simple working videocard can be, ($10 used) I don't know if I would beat my head against a wall to try to get it working. But if you want to experiment for fun, then by all means don't let me discourage. > > Naturally, the source code will not compile on FreeBSD as it > includes a number of headers which don't exist in FreeBSD, > and according to Roberts' web page the utility depends on > vm86, from which I surmise there is no simple way to make it > compile and run on FreeBSD, with or without linux > compatibility. Well I think porting the code would be more likely than getting the binary to work.
