I had to link the other libraries as well. I got it built. But when I run the application file It says segmentation fault(Core Dumped) . But I don see anything wrong with the pointers or anything that I have used. <br>Also when I include the (LIBS += -L/usr/local/lib/vtk-5.6 -lQVTK -lvtkRendering -lvtkIO -lvtkFiltering) .... in the .pro file I have this problem. Though I am not using any of its classes(QVTKWidget etc..,) But if I comment that line it works fine.<br>
<br>Its a run time error and is related to the Shared Libraries.<br><br>I have also set the LD_LIBRARY_PATH!!!<br><br>What Might have gone wrong. <br><br>I am totally stuck, Please Help me.<br>
