I tried to cross-compile it myself but partway through it bails out because it seems to think I should have pwd.exe on Linux. If someone could post either how to cross-compile gdb/gdbserver or simply post a build of gdbserver for DOS, I would be grateful. > > Is there a reason DJGPP doesn't include gdbserver with gdb? It would make debugging graphical programs for DOS much easier for everyone. I tried compiling gdbserver once, and the error message I got said "target not supported". So there's that :( Funny coincidence though, right now I am working on implementing the gdb remote protocol myself. As far as I can tell that's the only way to debug djgpp programs over a remote connection. The protocol itself isn't too difficult, but juggling exception frames around can be a bit tricky. https://github.com/jwt27/libjwdpmi/blob/master/src/debug.cpp Please excuse my shameless self-promotion.
