[vtkusers] QVTKWidget linux link error "relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; "

[Ashika Umanga Umagiliya]

Hi again Karthik,

I compiled my library by adding your code-snippet but still gave the same error.
So,I modified "VTK/GUISupport/CMakeLists.txt" file accordingly and now
it gives the following error complaning about   "libvtkRendering.a":

"umanga at akaishi:/work/svn-checkout/osaka3d/osaka3d/trunk/osaka3d/rinzo-platform/src/dlplugins/vtkviewer$
make
Linking CXX shared library
/work/svn-checkout/osaka3d/osaka3d/trunk/osaka3d/rinzo-platform/dist/plugins/libRzDLVTKView.so
/usr/bin/ld: /usr/local/lib/vtk-5.6/libvtkRendering.a(vtkActor.cxx.o):
relocation R_X86_64_32 against `a local symbol' can not be used when
making a shared object; recompile with -fPIC
/usr/local/lib/vtk-5.6/libvtkRendering.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: *** [/work/svn-checkout/osaka3d/osaka3d/trunk/osaka3d/rinzo-platform/dist/plugins/libRzDLVTKView.so]
Error 1
make[1]: *** [CMakeFiles/RzDLVTKView.dir/all] Error 2
make: *** [all] Error 2"

Do I have to modify the root CMake file of VTK ?

regards,
umanga
