GNUStep build problems

GNUStep build problems

[-- Attachment #1.1: Type: text/plain, Size: 431 bytes --]

Hi,

we are trying to add GNUstep support for Emacs in Gentoo Linux.
Unfortunately Emacs build fails from HEAD during bootstrapping, maybe
you can have a look at it, a log of the build process is attached.
Also there has been a linker problem as in Gentoo the GNUstep libraries
are not in FHS locations but in the ones recommended by GNUstep.  A
patch for that is attached.

CCing Gentoo Emacs and GNUstep teams.

This has been reported:

http://emacsbugs.donarmstrong.com/cgi-bin/bugreport.cgi?bug=620

Unfortunately, no one seems to have found the time to work on this yet.
Yavor Doganov's observation in that bug report is probably key:

Applied, thanks.

                                                    rule, but use a
                                                    variable.

The best would be to get rid of the #ifdef NS_IMPL_GNUSTEP, and use the
default rule for temacs${EXEEXT}, passing the correct flags in the
existing variables, or add new ones if needed.  Given that not too many
people work/even have access to GNUStep, help getting that right would
be greatly appreciated.

Now looking at the log:

./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --program-suffix=-emacs-23 --infodir=/usr/share/info/emacs-23 --without-carbon --with-sound --with-x --without-toolkit-scroll-bars --with-gif --with-jpeg --with-png --with-rsvg --with-tiff --with-xpm --disable-font-backend --without-freetype --without-xft --without-libotf --without-m17n-flt --with-x-toolkit=gtk --without-hesiod --with-ns --disable-ns-self-contained --without-kerberos --without-kerberos5 --with-gpm --with-dbus --build=i686-pc-linux-gnu
configure: WARNING: Unrecognized options: --without-carbon, --disable-font-backend
^^^^^^^^^^^^^^^^^^
This warning is obvious...

--with-x --with-x-toolkit=gtk make no sense when using --with-ns
--with-gif --with-jpeg etc, are turned on by default, no need to bother with them. 

You can try to get around the byte compilation problem by first
configure --with-x, do a make to create the .elc files, and then
reconfigure --with-ns and try again.  It's a hack, but it might help
until someone finds a proper fix.

I think this patch causes:  bug#760: Linker issues with the GNUstep build

Hmm, I believe it is because of Adrian's change -- putting $(LDFLAGS)
in YMF_PASS_LDFLAGS causes -Wl,... to be passed directly to the linker
via prefix-args and -Xlinker.

IIUC, this behavior is the direct consequence of the fact that the
GNUstep port of Emacs cannot be dumped (as of now).  It is not
necessarily a useful symptom.

I wonder if the patch in

http://emacsbugs.donarmstrong.com/cgi-bin/bugreport.cgi?bug=33

helps anyone with this problem?

 Yes, we fixed it meanwhile in Gentoo.

 Those --with- switches are automatically added depending on the user's
settings, we don't double check it as it does no harm.

 No real way for an automated build system...but we will hunt it.
