Hi,
First, in terms of my compiler build (referencing your previous post...) what I
had a problem with was building the sample C++ code that came with BrickOS. I
don't need C++ so I haven't investigated this any further. You're free to try my
build of the compiler and see what happens.
The problems you're reporting are in building the platform tools that are needed
to work with the RCX. BrickOS doesn't have support for OS X so they have to be
modified to work (namely getopt differences and USB code). I've done this using
libusb (which all of the BrickOS tools should be ported to since it's cross
platform). You can download them from
http://www.zapptek.com/Downloads/OSXBrickOSTools.tgz. If you have this then you
can skip that part of the Brick OS build (doing a more specific make or
modifying the Makefile...).
Let me know if you have any more questions about OS X support. I've been able to
build Brick OS and run it on my RCX so it's possible!
Michael
