Hi all ,I'm new to qt programming and qtcreator as well .I have been trying for the past few days to integrate qt with vtk 6 but with no success.I have built vtk 6 as per the instructions on the website but cannot be able to link it with the qt creator .Here's what I have done . I added the QVTKwidget on an empty form just to see whether it would compile but instead got linker file not found errors.I believe its the pro file configuration settings but i just don't know what to do and i've ran out of ideas.Here's what my .pro file looks like

Qt Code: 
  1. QT       += core gui
  2.  
  3. greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
  4.  
  5. TARGET = vtktest
  6. TEMPLATE = app
  7.  
  8.  
  9. SOURCES += main.cpp\
  10.         mainwindow.cpp
  11.  
  12. HEADERS  += mainwindow.h
  13.  
  14. FORMS    += mainwindow.ui
  15.  
  16. win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../../../../usr/local/lib/release/ -lvtkalglib-6
  17. else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../../../../usr/local/lib/debug/ -lvtkalglib-6
  18. else:unix: LIBS += -L$$PWD/../../../../usr/local/lib/ -lvtkalglib-6
  19.  
  20. INCLUDEPATH += $$PWD/../../../../usr/local/include/vtk-6.0
  21. DEPENDPATH += $$PWD/../../../../usr/local/include/vtk-6.0

I only linked to one lib file for illustration as there are many files using the addLibrary->externalLibrary..... method from qtCreator but i still get this error from the compile output although the file is clearly there .

Qt Code: 
  1. /usr/bin/qmake -spec /usr/share/qt4/mkspecs/linux-g++ CONFIG+=debug CONFIG+=declarative_debug -o Makefile ../vtktest/vtktest.pro
  2. g++  -o vtktest main.o mainwindow.o moc_mainwindow.o    -L/usr/lib -L/home/michael/code/vtktest/../../../../usr/local/lib/ -lvtkalglib-6 -lQtGui -L/usr/lib -L/usr/X11R6/lib -lQtCore -lpthread 
  3. /usr/lib/gcc/i586-suse-linux/4.7/../../../../i586-suse-linux/bin/ld: cannot find -lvtkalglib-6
  4. collect2: error: ld returned 1 exit status
  5. make: *** [vtktest] Error 1
  6. 15:39:29: The process "/usr/bin/make" exited with code 2.
  7. Error while building/deploying project vtktest (kit: Desktop)
