Try editing nextstep/compile and add

  -fconstant-string-class=NSConstantString

to the CFLAGS variable setting for the GNUstep case.  Then rm ../ 
config.log and invoke ./compile again.  (The other warnings are "OK"..)

At one point I needed that flag when compiling it under GNUstep, but  
then I stopped needing it and I'd assumed that it was because of some

I googled for a while after that reply, and found the same suggestion as you
gave. It works for compiling *.m to *.o, but there're still error messages
when gcc links *.o to `temacs', all are "undefined reference to
whatwhatwhat". I added `-lobjc' to the gcc link command line, some errors
gone, but still many like "undefined reference to NSxxx" and "undefined
reference to __objc_class_name_NSxxx". I searched the GNUStep directory,
found no *.a but only *.so. I'm stuck here.

OK, I'd forgotten that -fconstant-string-class=NSConstantString  
should have been set up in the Makefile already.  (That's why it  
wasn't needed in the config anymore.)  Take a look at src/Makefile.in  
and search for 'GNUSTEP'.  If the .m.o rule there wasn't making it  
into your actual Makefile, or was being ignored for some reason,  
that's the source of that problem.  The linking issue could be  
related, because those flags are also keyed off of #ifdef GNUSTEP, in  
src/Makefile.in and src/config.h.

I'm not sure what's happening in your case, but for the heck of it,  
you could try adding '-DGNUSTEP' to the CFLAGS in nextstep/compile --  
maybe there's something different on your system regarding how CFLAGS  
and CPPFLAGS are processed.

(I'm more than open to suggestions for improving any of this, if you  
can find something that works on your setup..)

thanks,
Adrian

[-- Attachment #1.1: Type: text/plain, Size: 2778 bytes --]

I can now get temacs and emacs built in src, after some work:
1) setup env variables:
export GNUSTEP_SYSTEM_ROOT=/usr/GNUstep/System
export GNUSTEP_MAKEFILES=$GNUSTEP_SYSTEM_ROOT/Library/Makefiles
export CPATH=$GNUSTEP_SYSTEM_ROOT/Library/Headers:$CPATH
export
LD_LIBRARY_PATH=/usr/GNUstep/System/Library/Libraries:$LD_LIBRARY_PATH

2) modify src/Makefile.in:
+#define GNUSTEP
#define THIS_IS_MAKEFILE
#define NO_SHORTNAMES

than configure and build:
# ./configure --prefix=xxx --with-ns --without-x
# make

I think it's better to define `GNUSTEP' in ./configure process.

But there's still problems! After src/emacs is built, the build process
proceeds to byte-compile elisp codes, and that makes a Segmentation fault:

make[1]: Entering directory `/home/sun/sandbox/emacs-23.0.0_NS-9.0pre1/leim'

make: *** [leim] Error 2

I can run temacs with `./temacs -q -nw' in src, but `./emacs -q -nw' failed
with the same "Segmentation fault". Maybe there's something wrong in the
dumping process? I tried to build temacs with -O0 and -O1, but none woks.

I think this relates to gnustep's recent config change to stop using  
environment variables.  I'll look into it..

Not sure if this is causing your particular segfault, but make sure  
you add -DCANNOT_DUMP to C/CPPFLAGS (see nextstep/compile).  And  
GNUSTEP _should_ be being defined if you use the compile script.   
(But probably in the long run GNUSTEP / COCOA should be defined in  
the appropriate place in configure.in as you say.)

Yes, -DCANNOT_DUMP solves the segfault problem, I can now "make install" : )
I did not use the nextstep/compile script, but performed its tasks one by
one manually.

But when I cd into nextstep/build/Emacs.app and run "./Emacs -q", I met
these error messages:

ns_init_paths: '/home/sun/sandbox/emacs-
23.0.0_NS-9.0pre1/nextstep/build/Emacs.app'

./Emacs: Uncaught exception NSInternalInconsistencyException, reason:

It seems there's something wrong with my GNUStep env, maybe the "backend"
part. I'm new to GNUStep, what's that mean? and what should I do?

Yes Jeff Teunissen and I had the same problem.
After straced it, it looks like that the app seeach the backend in wrong
paths.

Maybye introduced here :
2005-07-17 * Source/NSApplication.m (gnustep_backend_path,
	gnustep_backend_framework, gnustep_backend_bundle): New functions.
	(initialize_gnustep_backend): Support versioning of backend bundle.

ANN: Emacs.app 9.0-pre1

[Adrian Robert]

Hi all,

I'm happy to announce an initial release of the GNUstep / Cocoa port 
based on the unicode-2 branch:

http://emacs-app.sf.net/

It's available (see the site) both as a patch to 2005/11/05 CVS (+ 
mini-tarball) or a monolithic tarball.  It should build and run on Mac 
OS X 10.3 and 10.4, and GNUstep on at least Linux (that's the only 
system I have for testing).


What works:

- all the basics
- fringes
- proportional text
- images (except XPM)
- boxes/borders, etc.


What doesn't work:

- toolbars
- tooltips


What has glitches:

- non-ascii text rendering and keyboard handling
- font and font size selection
- ctrl-g handling (interrupt input is not (yet) used)
- image backgrounds (e.g., gnus)

For the last, note that images are displayed via compositing, so the 
problem only comes up for images without an alpha layer whose 
background does not match the local face.


Why this Port?

Although there is already an existing port of GNU Emacs to Mac OS X, 
the "Emacs.app" port offers three advantages over it:

1) it runs in addition on the free GNUstep implementation of the Mac's 
Cocoa APIs (which are based on NeXT/OpenStep);

2) it makes a more concerted attempt to take advantage of the desktop / 
UI facilities both OS X and GNUstep offer for font and color selection, 
setting preferences, and so on, without compromising emacs's 
functionality;

3) because Cocoa is a higher-level API than Carbon, the windowing code 
is about half the size, and hopefully correspondingly easier to 
maintain.

On the other hand, the Carbon port supports OS X 10.1 and 10.2, plus 
Mac OS 8 and 9, and it is currently more complete, bug-free, and 
probably more stable than Emacs.app.


Why the 9.0 version number?

Emacs.app actually dates back to the early 1990s when Emacs 19 was 
ported to the NeXT computer.  The NeXTstep windowing APIs used on that 
machine became the basis for first OpenStep, then Rhapsody, then MacOS 
X.  Emacs.app has been kept updated by various people for most of that 
time.


What about Emacs 22?

I believe Emacs.app could trivially be converted to work off of the CVS 
Head codebase, however without some additional Mule <-> UTF conversion 
code I embedded into Emacs on Aqua, it will not render non-ASCII 
characters.  This code was written by Otried Cheong 
(http://tclab.kaist.ac.kr/~otfried/Mule/) and I have not asked him what 
the copyright status of that code is.  In addition, there is not nearly 
sufficient time for the implementation to be finished, debugged, and 
integrated before the initial 22 release.


Note on the implementation

I mostly followed the Carbon port in updating the Makefiles and 
configuration.  However MAC_OSX and MAC_OS are UNdefined when compiling 
for NS due to these being used for Carbon-specific things.  Unexec 
seems to work perfectly using Andrew Choi's unexmacosx.c, however I 
haven't been able to get dumped images to run under GNUstep.


regards,

I think if we all agree that this is intended to be included in some (not
too distant) future release of Emacs, it would be good to put it on a branch
in the CVS.  The only reason not to do that yet is if some legal paperwork
is still pending.

Hopefully this branch can "quickly" be merged into the unicode branch
(AFAICT the main criteria for this would be that the patch doesn't
introduce any bug in the other ports, including the Carbon port).
