Well, after a fairly frustrating couple of days, I was finally able to build
legOS-0.2.5 yesterday evening. I will get to the details in a minute.
The whole experience made me question the stability of Cygwin/GCC.
Basically, I tried at least 3 different versions of binutils (most of which
did compile) and 3 different version of gcc (none of which compiled without
error).
I was very happy to find a precompiled (binutils/gcc) tool set on the
hitachi web site! Available at:
http://semiconductor.hitachi.com/tools/software_downloads.html
The file is actually:
http://semiconductor.hitachi.com/tools/2000r1_i686-cygwin32-x-h8300-hms.zip
Now this morning, I see http://news.lugnet.com/robotics/rcx/legos/?n=2470.
Apparently some compile error(s) encountered in building gcc don't effect
the portions of gcc needed to build legOS. I may have been frustrated for
no good reason 8-)
I was however, not able to use util/dll to send a program to the RCX last
night, so further investigation is needed.
<details>
Win2k, Cygwin (latest version... reinstalled yesterday), h8300 toolchain
downloaded from Hitachi's web site (prebuilt executables for Cygwin)
I installed Cygwin (selected all packages, then removed a couple I knew I
would not need... like Mail.)
1) Installed (decompressed) the h8300 tools.
2) set the PATH to the tool directory.
3) Installed legOS-0.2.5
4) Changed Makefile.? to use gcc instead of gccw32 (gcc.exe included in
tools)
5) executed the following:
make realclean
rm boot/.depend
make
6) encountered errors with the new .depend file created during the build...
so I had to execute:
tr -d '\15\32' < boot/.depend > boot/.depend
// NOTE: This will strip the ^M and ^Z from the file (dos to unix text)
7) executed:
make
8) encountered errors concerning inproper use of void for motor_x_speed and
motor_x_direction calls in dmotor.c and dmotor.h I fixed that error by
removing the const specifier in front of the func. decl. then:
make
util/firmdl3 boot/legOS.srec
That is as far as I was able to get. It was already 1:30am 8-)
</details>
I hope others attempting to build legOS on Cygwin will benefit from this
information. (I guess I would rather download the prebuilt tools as opposed
to building them...) My concern is the errors I encountered at steps 7&8.
I guess I am wondering how often the hitachi site gets updated with new gcc
builds.

Max: Did you get any compile errors? You said "built and worked fine for
me." I am only asking since I had so many attempts end with compile
errors... even unmodified GNU releases.
<dreaming>I am hoping that we can get a solid setup that works for everyone
