OS X 10.6.1 FPC 2.2.4 Xcode 3.2 (64 bit)

Using code base that has complied correctly since 2004

Fixed $MODE OBJFPC

Current problems

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
Created by Paul Davidson on 2005/01/01.

unit cStack;

   {$I Directives.inc}

interface
uses

   SysUtils;
   type
     tccStack = class( TObject )   {Barfs here}

2) All .s files give a "Command /Developer/usr/bin/gcc-4.2 failed with exit code 1

Any suggestions?

Thank you

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.

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. ***

Thank you

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