Matt,
I have been working with Michael Zapp on "porting" brickOS to the Mac OS X.
We too had a fairly easy time with the binutils (ver 20020918). And both of
us had issues with GCC although we have been working on Ver 3.1. I have not
kept up with our updates but as just noted binutils is built and Michael has
a build of gcc. (But this is from GCC source code and I am extremely
cautious about this approach. Just look at the differences between the two
code bases). Also Michael has been tackling the issue of USB communication
(I can add more about this if requested). Both of us have been busy lately
and I have not updated with him in a couple of weeks. I will check in with
him. A few notes here ...

Don't forget the make install step.

Where did you get the source for 2.95.3? I have a few issues with the way
Apple seems to label there distributions. I find it difficult to reconcil
their version numbers with the GCC versions. I also find it extremely
difficult to find any versions except the latest.

Could you please post your instructions here? Thanks!

Not sure about this. I would want to see you instruction set and
modifications before I would start to guess.

Glad to have another work on this. As I mention above I am going to be busy
for another couple of weeks. (I am going to try again at the annual MATLAB
Programming Contest sponsored by The MathWorks, See ). And when I get back
to this I have real limited access to a Mac. But it is good to have another
working on this problem.

| Ed, thanks for the quick response. I wrote out a reply, deciding that I would scrap 2.95 and just go for 3.1, but then I got an email pointing out the problem I was having was a bug in binutils. So now with binutils-2.13.2.1, everything compiles (...) (21 years ago, 28-Mar-03, to lugnet.robotics.rcx.legos)

| I'm trying to compile BrickOS on Mac OS X. I'm actually surprised at how well it's been going considering it looks like no one has tried it yet. I've compiled gnu binutils-2.13.1 hosted on darwin6.4, targeted at h8300. That seemed to work fine out (...) (21 years ago, 28-Mar-03, to lugnet.robotics.rcx.legos)
