Problems with compiling GNUstep

[Philippe C . D . Robert]

Hi,

after a long time using a more or less stable GNUstep installation I decided to 
install LaunchPad 1.0.1 plus gnustep-gui/xgps 0.6.8. I removed the complete 
GNUstep installation and did it as explained in the various INSTALL files. But 
somehow I could not compile the Tools within xgps:

shared_obj/ix86/linux-gnu/gnu-gnu-gnu/font_cacher.o: In function `main':
shared_obj/ix86/linux-gnu/gnu-gnu-gnu/font_cacher.o(.text+0x7d9): undefined 
reference to `XDisplayName'
shared_obj/ix86/linux-gnu/gnu-gnu-gnu/font_cacher.o(.text+0x7f1): undefined 
reference to `XOpenDisplay'

shared_obj/ix86/linux-gnu/gnu-gnu-gnu/font_cacher.o(.text+0xc25): undefined 
reference to `XListFonts'
<snip>
make[3]: *** [shared_obj/ix86/linux-gnu/gnu-gnu-gnu/font_cacher] Error 1
make[2]: *** [font_cacher.build] Error 2
make[1]: *** [font_cacher.all.tool.variables] Error 2
make[1]: Leaving directory 
`/home/phr/Developer/GNUstep/gnustep-xgps-0.6.8/Tools'
make: *** [internal-all] Error 2

I have XFree86 4.0.3 installed on my Linux box. I also noticed that I had to 
create a symlink from /usr/X11R6/include/X11 to /usr/include/X11 otherwise 
SharedX wouldn't compile!

When I then try to compile a GNUstep app, I get link errors, ie.

/usr/local/GNUstep/System/Libraries/ix86/linux-gnu/gnu-gnu-gnu/libgnustep-gui.so:
 undefined reference to `initialize_gnustep_backend'
/usr/local/GNUstep/System/Libraries/ix86/linux-gnu/gnu-gnu-gnu/libgnustep-gui.so:
 undefined reference to `NSHighlightRect'
/usr/local/GNUstep/System/Libraries/ix86/linux-gnu/gnu-gnu-gnu/libgnustep-gui.so:
 undefined reference to `NSRectClip'
/usr/local/GNUstep/System/Libraries/ix86/linux-gnu/gnu-gnu-gnu/libgnustep-gui.so:
 undefined reference to `GSWViewIsFlipped'

and so on...

I probably missed something, but... any ideas?

PS: I really liked the gnustep-core package, where I could do *one* 
./configure;make;make install cycle to do everything!
