I choose the CentOS machine for now and did the following:

        yum install gcc
        yum install gcc-objc
        yum install make libpng libpng-devel libtiff libtiff-devel libobjc 
libxml2 libxml2-devel libX11-devel libXt-devel libjpeg libjpeg-devel

        cd /usr/src
        gunzip gnustep-startup-0.32.0.tar.gz
        tar xvf gnustep-startup-0.32.0.tar
        cd gnustep-startup-0.32.0
        ./configure

This got me

So far so good! I tried to build

        make

and got

 Compiling file objc-load.m ...

/usr/bin/ld: final link failed: Bad value

gmake[5]: *** [obj/libgnustep-base.so.1.24.6] Error 1

OK, let's see

        make clean
        export CC="gcc -m64 -fPIC"
        make

No avail!?

Any idea?

Thanks a lot,
