With access to a Mac OS X 10.2 this week I have made an attempt to build the
cross compiler set under Mac OS X. Currently I have an issue with sysinfo.c
with the binutils build. But for those interested here are my steps so far.
I will post more as i hopefully get over these roadblocks. WARNING! WARNING!
WARNING! I have NO prior experience with the Mac or Mac OS X. So use these
instructions AT YOUR OWN RISK. I am NOT responsible for any damage you
might cause to your machine.
1. Registered with Apple Developer Connection, ADC.
2. From the Apple Developer Site, I downloaded the Mac OS X Developer Tools
December 2002. NOTE: This set of tools requires Mac OS X 10.2.x
3. Installed the following packages within the Development Tools: Developer
Tool software, Mac OS X SDK, Developer Documentation, Developer Example
Software, December 2002 Dev Tools extras. I don't believe I needed all
these but installed them anyways.
4. Created a subdirectory \Developer\Projects\brickOS\build
5. Downloaded gcc-7 and binutils-200020918 from the Apple Darwin projects
site, http://www.opensource.apple.com/projects/darwin/6.0/projects.html.
NOTE: The gcc-7 package appears to be gcc-2.95.2 and not gcc-3.1 which
binaries come with the Developer Tools. I was not sure where to find the
newer gcc3.1 and have just decided to try gcc-2.95.2 for now.
6.Copied the tar.gz packages to the dir above.
7.Modified the h8300 cross compiler build script for cygwin written by Paolo
Masetti. I have included the modified script below. I placed it in the
\Developer\Projects\brickOS\build directory.
8. Opened a terminal and typed at the prompt
username% sh buildgcc.sh
WARNING!WARNING!WARNING! Once again this gets me so far as a error in build
binutils. Please take caution with these steps.

# Partial comments from original version follows.
#
# This document contains complete instructions on how to create a GNU-
# based cross compiler (C and C++) for use under Windows NT 4.0 and Cygnus
# Cygwin 1.0 and later (not the older Cygwin B20.1). These instructions are
# based on information provided by David Fiddes, who has a build of an
# earlier version of the GNU cross-compiler which seems to be intended for
# Cygwin B20.1. His build is available on his website (see below).
#
# ------------------------------ Notes ------------------------------
#
# 1. These instructions and script will not work with Cygwin B20.1
# (older free version). This version of Cygwin does not have all of the
# utilities or set up certain aspects of the Unix environment that are
# required. Essentially the same things can be accomplished with B20.1
# as with the commercial version 1.0, but the instructions would be a
# bit more complicated, and the resulting environment would not be very
# usable by a typical Unix programmer.
#
# 2. The most frustrating problems I had getting this build to work had
# to do with the addition of carriage returns by various software. This
# is the first thing I'd check if something goes wrong. The two things
# that got me were WinZip (which I was using at first to extract the
# archives), which adds CR's by default, and the Cygwin file system,
# which somehow got setup in text mode, even though the "mount" command
# was showing me "binmode". I solved the former by avoiding WinZip and
# just using the "tar" command from within the Cygwin environment. When
# using WinZip you can disable the "TAR file smart CR/LF conversion"
# option in "Options/Configuration/Miscellaneous". I solved the latter
# by completely removing Cygwin and reinstalling. You should make a
# simple program that can quickly tell you if a particular file has any
# CR's. I wasted a lot of time trying to diagnose such "simple" problems.
#
# The following program is called "showcr.c", which I use to determine
# whether a given text file contains carriage returns.
#
# #include <stdio.h>
# #include <stdlib.h>
#
# int main(int argc, char *argv[])
# {
# FILE *in;
# int i;
# if (argc != 2) {
# fputs("Usage: showcr <infile>\n", stderr);
# exit(1);
# }
# if (!(in = fopen(*++argv, "rb"))) {
# fprintf(stderr, "showcr: can't open %s\n", *argv);
# exit(1);
# }
# while((i = fgetc(in)) != EOF)
# {
# if (i == 13)
# {
# putchar('^');
# i = 'M';
# }
# putchar(i);
# }
# fclose(in);
# return 0;
# }
