Thank you
Changing the mode in the project fixed all problems. System now
compiles correctly.

What exactly did you fix and how? Marco mentioned something about
duplicate mode switches, but if you want help you really have to be
more specific.
1) A unit with identical first few lines as several other
successfully compiled units gives a 'Identifier not found "class"
error. Following is start of file:
{
tccStack.pas
corax60

}
unit cStack;
{$I Directives.inc}
interface
uses
SysUtils;
type
tccStack = class( TObject ) {Barfs here}
It means that the file is not being compiled in Delphi or ObjFPC
mode. What happens if you add {$mode objfpc} before the {$i
Directives.inc} statement? Does the compiler then complain about an
illegal/duplicate mode switch? What are the contents of that
Directives.inc file?
Note that the default compilation mode for the Xcode projects is
MacPas mode (set via the command line options; see the "FPC Xcode
ReadMe.rtf" on the installer disk image for information about where
you can see and change these parameters), so if you don't add any
{$mode xxx} statement, that's what your code will use.
2) All .s files give a "Command /Developer/usr/bin/gcc-4.2 failed
with exit code 1
How did you create the project? Did you use a template included with
FPC 2.2.4? (if so, which one) Are the errors for units that are
actually used by your main program? If not, have you tried following
the these instructions from the "FPC Xcode ReadMe.rtf" file on the
installer disk image under point "6. Troubleshooting and FAQs":

1) Q: What can I do when getting the following error after building:
powerpc-apple-darwin8-gcc-4.0.1: warning: '-x assembler-with-cpp'
after last input file has no effect
powerpc-apple-darwin8-gcc-4.0.1: no input files
powerpc-apple-darwin8-gcc-4.0 failed with exit code 1
• A: Short answer: click on the disclosure triangle next to the
Targets group, then next to the target with the same name as your
project, and then next to its "Compile Sources" phase. Remove any
sources from that phase which are not actually used by your program.
Long answer: the projects work in two phases. First, FPC is used to
compile all sources from Pascal to assembler code. Next, Xcode calls
gcc to assemble the resulting files, links them together and builds
the application bundle (Xcode refuses to link if we let FPC directly
generates object code). If you remove a unit from the uses clause of
your program, FPC will no longer compile this unit. Subsequently,
there will be no assembler code for gcc to assemble, and Xcode will
pass an "empty filename" to gcc, causing the error displayed above.
