If "low cost" is your discriminator, you can't get much less expensive
than GCC/EGCS. The cygwin directory on an NT box I have is only about
32MB (add 22MB for emacs), whereas the M$VC++ directory tree on the
same box consumes 700MB; so "small" is another word I'd apply to
cygwin. (Of course, that copy of cygwin contains the native x86
compiler, but I can't imagine the H8 compiler would be *that* much
larger.)
Now, I'm aware that GCC/EGCS has shortcomings, particularly as
compared to the (expensive) native compilers on many platforms, but as
a hobbyist on a limited budget myself, I consider the GNU compiler
(and related development programs) to be the finest tools in my kit.
BTW, I'm using egcs-1.1.1 on Linux to develop a c++ firmware
replacement. When I get a little more functionality into it, I'll
post details.

d.

| Do you have a URL of where to download the GCC/EGCS compiler? Yes, I'm lazy and don't wish to hunt it down. :) I tried searcing this NG for 'compiler' but did not find a ref. for this one in the messages located. thanks, -Wes dave madden wrote: (...) (26 years ago, 4-Feb-99, to lugnet.robotics)

| I've just compiled a copy of egcs-1.1.1 on NT, using the cygwin gcc. These compilers (C and C++) and other related utilities can be used by Windoze users to compile legOS (or your own replacement firmware). The archives (rcx-tools.tar.gz and (...) (26 years ago, 4-Feb-99, to lugnet.robotics)
