(...) For me, at least, it's not hanging during dll. My earlier problem was that dll just wouldn't complete with my program, but it didn't crash the RCX. By the way, I think I've found my crashing problem. It looks like I had some LCD calls that (...) (25 years ago, 29-Feb-00, to lugnet.robotics.rcx.legos)

I've also been struggling with building the cross compiler. I'm trying to create a DJGPP hosted version. Once I am successful, we will be able to use Markus's legOS on DOS/Windows as-is. Currently, I have to rewrite Makefile.Common, Makefile.Kernel, (...) (25 years ago, 28-Feb-00, to lugnet.robotics.rcx.legos)

(...) This may not be the case- the cross-compiler will try to compile something, but at least with the directions most of us use, there is no standard C library created and so the compiler thinks it doesn't work. The trick (then) is to use Markus's (...) (25 years ago, 28-Feb-00, to lugnet.robotics.rcx.legos)
