Apps compilation fails (RedHat7.1)

[D'hondt Olivier]

Hello,
I have installed these rpm packages:

Name        : gnustep-gui
Version     : 0.7.0
Release     : 1

Name        : gnustep-base
Version     : 1.0.2
Release     : 1

Name        : gnustep-objc
Version     : 1.0.1
Release     : 1
 
Name        : gnustep-make
Version     : 1.0.1
Release     : 1

Name        : gnustep-xgps
Version     : 0.6.9
Release     : 1
 
Name        : gnustep-base-debug
Version     : 1.0.2
Release     : 1
 
Name        : gnustep-gui-debug
Version     : 0.7.0
Release     : 1
 
Name        : ffcall
Version     : 1.8b
Release     : 1 
                  
And when i try to 'make' applications like GWorkspace,
the compilation fails, and I get this:

  
shared_obj/ix86/linux-gnu/gnu-gnu-gnu/Fiend/FiendLeaf.o(.text+0x199f):

shared_obj/ix86/linux-gnu/gnu-gnu-gnu/Fiend/FiendLeaf.o(.text+0x1afd):

shared_obj/ix86/linux-gnu/gnu-gnu-gnu/Fiend/FiendLeaf.o(.rodata+0xac):
undefined       

I get similar things with other gnustep apps.
My distribution is RH7.1.Any suggestions ?
