All GNUstep apps have blank windows, and lots of apps won't compile

[Samuel Harvey]

Blank windows problem:
----------------------

Running any GNUstep app displays a collection of windows that are
entirely white or black. The window decorations display correct window
names (e.g. Inspector). If I click where the Quit button should be on
the menu, it will quit.

I have attempted compiling modules/core/back to use various graphical
backends. I have turned off text-antialiasing as specified in the FAQ
( http://wiki.gnustep.org/index.php/User_FAQ#Troubleshooting ).

This happens using the packages built for my system (Debian Linux
testing), as well as the svn trunk.


Compilation problem:
--------------------

These will not compile (modules/dev-libs):
db        ( http://pastebin.com/f56b9edbb )
gdl2      ( http://pastebin.com/f80b962f )
gscrypt   ( http://pastebin.com/f383838ac )
gsgd      ( http://pastebin.com/f3c303ebe )
gsweb     ( http://pastebin.com/f4a1c5755 )
guile     ( http://pastebin.com/f4f973a7f )
java      ( http://pastebin.com/f728faff0 )
smbkit    ( http://pastebin.com/f66789139 )

Representative error message (from db):
***
In file included from exceptions/EOFExceptions.m:30:
../eoaccess/EOEntity.h:31:33: warning: extensions/GCObject.h: No such
file or directory
../eoaccess/EOEntity.h:32:32: warning: extensions/GCArray.h: No such
file or directory
../eoaccess/EOEntity.h:33:37: warning: extensions/GCDictionary.h: No
such file or directory
***

All of those files do exist in
/usr/GNUstep/System/Library/Headers/GNUstepBase/, but there is no
folder on my system named extensions that contains those files.

The section in the User FAQ on compilation problems didn't seem to
apply if I understood correctly; LD_LIBRARY_PATH is the same for my
user and for root, not to mention that I'm not compiling as root.
Compiling as root gives the same error.


Probably relevant system information:
----------------------------

Debian GNU/Linux (testing) lappy02 2.6.26-1-686 #1 SMP
gcc version 4.3.2 (Debian 4.3.2-1)
GNUstep version: trunk rev 26848


Since GNUstep seems to be compiling and working for everyone else, I'm
obviously doing something wrong.
