Trouble building projects on SuSE

[Randy J. Zauhar]

Hi Folks,

I have successfully built GNUstep on a number of platforms, but there is always 
something new to go wrong!

This time I am working under SuSE ( openSUSE 12.1 (x86_64) ). In the past I 
built everything from downloads, this time I tried using zypper to install 
everything.

I backed up to gcc 4.5 (because of some initial errors + discussion thread 
warnings, maybe all a red herring). Zypper reports the following gcc-related 
items as installed:

i | gcc45                             | The GNU C Compiler and Support Files    
                              | package
i | gcc45-c++                         | The GNU C++ Compiler                    
                              | package
i | gcc45-fortran                     | The GNU Fortran Compiler and Support 
Files                            | package
i | gcc45-info                        | Documentation for the GNU compiler 
collection                         | package
i | gcc45-locale                      | Locale Data for the GNU Compiler 
Collection                           | package
i | gcc45-obj-c++                     | GNU Objective C++ Compiler              
                              | package
i | gcc45-objc                        | GNU Objective C Compiler                
                              | package
i | libgcc45                          | C compiler runtime library              
                              | package
i | libgcc46-32bit                    | C compiler runtime library              
                              | package

NOTE that I did NOT remove libgcc46-32bit, as zypper warns that it will 
'downgrade' dozens of apps and libraries to 32-bit, with dire consequences to 
follow, I am sure.

The following GNUstep items are reported :

i | gnustep-back                  | The GNUstep Cairo Backend Library           
 | package
i | gnustep-back-doc              | GNUstep Cairo Backend Library Documentation 
 | package
i | gnustep-base                  | GNUstep Base library                        
 | package
i | gnustep-base-doc              | GNUstep Base Library Developer 
Documentation | package
i | gnustep-gui                   | The GNUstep GUI Library                     
 | package
i | gnustep-gui-doc               | GNUstep GUI Library Documentation           
 | package
i | gnustep-make                  | GNUstep Makefile Package                    
 | package
i | gnustep-make-doc              | GNUstep Makefile Package Documentation      
 | package

GNUstep was loaded from this repo:

# | Alias                              | Name                               | 
Enabled | Refresh
--+------------------------------------+------------------------------------+---------+--------

Yes     | Yes

SO, everything seems OK, but when I source the GNUstep environment and try to 
build a trivial tool, I get this:

# make
This is gnustep-make 2.6.0. Type 'make print-gnustep-make-help' for help.
Making all for tool LogTest...
 Linking tool LogTest ...

collect2: ld returned 1 exit status

It bitches about  'incompatible' /usr/lib/libgnustep-base.so - however, I see

# file /usr/lib/libgnustep-base.so.1.22.0
/usr/lib/libgnustep-base.so.1.22.0: ELF 32-bit LSB shared object, Intel 80386, 
version 1 (SYSV), dynamically linked, 
BuildID[sha1]=0x98b3eaa5772d648cba3f519387a6b6564e3c8f2a, stripped

and my tool object :

 # file obj/LogTest.obj/source.m.o
obj/LogTest.obj/source.m.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 
(SYSV), not stripped

They are both 32-bit so what is the deal? Is this a library version issue? I 
see that the latest GNUstep base is 1.24.3, where I have  1.22.0 installed, so 
could that lead to some incompatibility? But, incompatible with what?

Any advice appreciated!!

"The collapse will not be televised. Ignored and alone, each of us will 
experience it singly. As blemish and accusation, you will be photoshopped from 
the American Dream group portrait. The lower you slip, the more invisible you 
will become. The disconnect between what's real and what's broadcast will 
become even more obscene by the day."
