I was able to get one of my applications to compile and mostly run. When I try to close a window the application dies with "Bus Error".
I do use a special wrapper around the 'TopWindow' class to store user preferences (window size and placement). I point the WhenClose callback to my save preferences function... could that cause the problem?

There used to be a Core on exit bug, but we did fix it. Where does gdb say it died? If you run the program as
# ./myapp -args
use
# gdb ./myapp
gdb> run -args
and use "bt" to get the backtrace once it cores.
Universal build:
In Build Environment I add Compiler flags "-arch i386 -arch ppc" to the method I want, or all of them. (debug, size, speed). If you on a ppc mac you also need to add
"-isysroot /Developer/SDKs/MacOSX10.4u.sdk"
You need the same options when linking, but alas, there is no way to set Link options with U++ based on the platform, or triggered based on your current Building method.
I get around that by using Package Organiser / Add Link Options / WHEN "OSX11" with flags:
"-arch i386 -arch ppc"
again, on PPC, you additionally need to make it:
"-syslibroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386"
Finally, "ar" on OsX is the Gnu "ar" (as in, untouched) and can not handle fat files. You can change the ide sources to use "libtool" instead of ar, by editing CppBuilder.cpp and GccBuilder.cpp.
Or, replace "ar" with a script (temporarily) if you want (or, place it elsewhere, and fiddle with your PATH, there isn't just one way to fix things in Unix).
My "ar" script looks like:
#!/bin/bash
# It is valid to say "ar rc libfoo files.o"
shift
# Skip all arguments
done=0
while [ $done == 0 ]
do
case "$1"
in
-*) shift
;;
*) done=1
;;
esac
done
# Get output name
out=$1
shift
echo libtool $* -o $out
exec /usr/bin/libtool $* -o $out
Alas, you need all support libraries to also be Universal, ide that means libpng at least. You can compile it yourself using the nice ./configure line, or, fight with "port" to do it for you. If you are doing Universal of your own App, you'll have to work out your own dependencies.
Configure line that works on many things:
env CFLAGS="-O -g -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc" LDFLAGS="-arch i386 -arch ppc" ./configure --disable-dependency-tracking

That core dump was due to Xft and missing fonts I thought. It does not read (because it is not there?) the /etc/fonts.conf. Don't do not forget to install the X11 Application from CD1 on OsX, it is optional. I believe it also has a patch, so run Software Updater.
I was using ppc 10.4.8 and now Intel 10.4.8 and 10.4.9. Version made no difference when compiling, but only shared compile worked.
I can show the settings I use if it helps.
I can do a new .dmg too, I've been waiting for final version, but if you prefer rc5, I have the exe just sitting here.
The Mac default keys for Home/End is cmd-cursor down/up, you have no idea how annoying that is to get used to, but soon will! 
ps. I noticed the double font problem went away when I stick it in a bundle, so I guess OsX cleans up Environment Variables for me. So not considering it an issue at all now.

Yes, that is what I thought, but I am not quite able to fix the problem

X11 installed... I have also installed some ports, including xft (most likely not quite necessarry), but still stuck at that Bus error.
However, /etc/fonts.conf does not sound familiar; I have /etc/fonts/fonts.conf? (Have to check...)

Would be nice. At the moment, I quite confused with all that Mac thing

That is OK, once I have TheIDE capable of compiling, future is bright

Using MacPorts, I installed:
"port install zlib"
"post install libpng"
I did not need to install anything Xft and the like. This is on three machines now (from scratch too, OsX install CD on).
But in case it matters:

Sorry guys, I should have been checking the forumns a little more. Did you get the problem solved?
A couple things:
1) The home/end key is extremely annoying... but you can, at least, fix a few applications like Terminal to behave as expected.
2) I did not ever install anything from Mac ports. As I recall, the only thing I had to install was libpng. I just downloaded it from the the libpng site and it compiled cleanly. I, of course, installed X11 first from the DVD.
3) I have used theide and my software on PPC: 10.3.x and 10.4.{8,9}, and Intel: 10.4.{8,9} without major issues.
4) I can not get a Universal app compiled with theide... but I can manually from a terminal.
5) I have to edit Core/Core.h to include flagNOGTK in the OSX11->GUI area. Could we default that to include it, since I doubt many OSX users have GTK?

1: I agree Same in Mozilla/Seamonkey - typing an email is extremely annoying.
2: It needs libpng, how you install it is up to you. "ports" is just extreme convenient. In future, the extra libraries should be in the ide Bundle and fixed to look there. I saw a guide on it somewhere, but I have not done so yet.
3: Good.
4: I wrote a guide on how to do Universal. You need more compiler arguments, link arguments and finally, hack your "ar" to be better. Don't forget that any library you link against should be UB (libpng).
5: You can add -DflagNOGTK to Build Environment instead. Then it is still optional.
Acutally no, 4 linking only needs UB libraries if you are doing static linking, which I do with OpenSSL in my own project.
