I am trying to install vtk-5.0.3 using the following flags USE="-qt3 qt4 examples" emerge sci-libs/vtk Note that i want to build vtk using qt4 rather than qt3. vtk builds fine, but when it come to compiling examples it fails like this Linking CXX executable /var/tmp/portage/sci-libs/vtk-5.0.3/work/VTK/bin/qtsimpleview CMakeFiles/qtsimpleview.dir/main.o: In function `main': main.cxx:(.text+0xcf): undefined reference to `QApplication::setMainWidget(QWidget*)' collect2: ld returned 1 exit status gmake[5]: *** [/var/tmp/portage/sci-libs/vtk-5.0.3/work/VTK/bin/qtsimpleview] Error 1 gmake[5]: Leaving directory `/var/tmp/portage/sci-libs/vtk-5.0.3/work/VTK/Examples/All' gmake[4]: *** [GUI/Qt/SimpleView/CMakeFiles/qtsimpleview.dir/all] Error 2 gmake[4]: Leaving directory `/var/tmp/portage/sci-libs/vtk-5.0.3/work/VTK/Examples/All' gmake[3]: *** [all] Error 2 gmake[3]: Leaving directory `/var/tmp/portage/sci-libs/vtk-5.0.3/work/VTK/Examples/All' make[2]: *** [VTKExamples] Error 1 make[1]: *** [Examples/CMakeFiles/VTKExamplesTarget.dir/all] Error 2 make: *** [all] Error 2 !!!

Hi Rajil, Could you please try if emerging qt4 with USE="qt3support" solves this issue. Thanks, Markus
Hi Markus, Thanks for the hint. With qt3support enabled it worked :). Maybe a warning can be added to the vtk ebuild about this. Cheers, Rajil
Great! I will change the ebuild so it will terminate right at the beginning of the emerge should qt4 be installed without "qt3support". Thanks, Markus
Also works for me, but I wonder if the problem does not lie with VTK. Should a USE=qt4 build depend on qt3 calls?
(In reply to comment #5) > Also works for me, but I wonder if the problem does not lie with VTK. Should a > USE=qt4 build depend on qt3 calls? > Here's my stand on this and I might very well be wrong ;) I'd say the problem is VTK's combined with qt4 or rather the way qt4 is distributed within gentoo. qt4 provides backward compatibility functions for qt3 and as long as qt4 is build with this support enabled, qt4 code that uses some of these calls compiles fine. However, as soon as qt3support is missing, code like this won't compile any more. In any case, "mixed" qt3/qt4 code like this even though it is supported by qt4 really isn't clean and deprecated and the VTK folks will have to spend some time porting it to qt4 all the way rather than just hacking their previous qt3 code and relying on qt4 to provide the proper bindings. Best, Markus
