Hi,

I wanted to compile gnustep on cygwin and I followed the following guide:
http://gnustep.made-it.com/BuildGuide/

I can sump up by :

A) GNUstep-make
svn co http://svn.gna.org/svn/gnustep/tools/make/trunk/ gnustep-make
cd gnustep-make
./configure --prefix=/usr/GNUstep --with-layout=gnustep \ 
--with-config-file=/usr/GNUstep/Local/Configuration/GNUstep.conf
make && make install
cd ..

B) Setup GNustep
. /usr/GNUstep/System/Library/Makefiles/GNUstep.sh
and add the following lines at the bottom of /etc/profile:
# Setup GNUstep variables so we can run/compile stuff
echo Setting up GNUstep Environment...
. /usr/GNUstep/System/Library/Makefiles/GNUstep.sh

C) GNUstep-base
svn co http://svn.gna.org/svn/gnustep/libs/base/trunk/ gnustep-base
cd gnustep-base
./configure --enable-libffi
--with-default-config=/usr/GNUstep/Local/Configuration/GNUstep.conf
make && make install
cd ..

D) GNUstep-gui
svn co http://svn.gna.org/svn/gnustep/libs/gui/trunk/ gnustep-gui
Apply this patch :

cd gnustep-gui

D)GNUstep-back
svn co http://svn.gna.org/svn/gnustep/libs/back/trunk/ gnustep-back
cd gnustep-back
./configure --enable-server=x11 --enable-graphics=cairo
make && make install

and I get the following error


Making all for bundle libgnustep-back-017...
 Linking bundle libgnustep-back-017 ...
/usr/lib/gcc/i686-pc-cygwin/4.3.4/../../../../i686-pc-cygwin/bin/ld: Dwarf
Error: found dwarf version '0', this reader only handles version 2 and 3
information.

make[3]: *** [internal-bundle-run-compile-submake] Error 2
make[2]: *** [libgnustep-back-017.all.bundle.variables] Error 2

I understand that GNustep is using a missing reference but I find the
error message
about dwarf a bit weird.



Is it normal ?
