[Paraview] Question on Image reader

[Thorsten Hater]

Hello again,

after organizing my project and working out VTK and CMake everything  
seemed
to go right, save the detail that PV could not load the plugin.
Linking some shared libraries should resolve this, but if I try, I get  
an error related
to the shared objects:

/usr/bin/ld: /home/th/lib/Linux-x86_64/libgdif2.a(Block.o): relocation  
R_X86_64_32S
against `a local symbol' can not be used when making a shared object;  
recompile with -fPIC
/home/th/lib/Linux-x86_64/libgdif2.a: could not read symbols: Bad value

After recompiling the external library with -fPIC enabled and the  
plugin code as well,
the error still remains unchanged.
Has someone else encounter this problem?

Best regards
