I am developing an application using QT 4.6 and VTK 5.4 with CMake 2.8. However, I am having troubles compiling with QVTK. Here is an overview of my situation.<br><br>I am trying to compile the VTK Qt ImageViewer example as a test for using the QVTK widget. This example is in the source tree at Examples/GUI/Qt/ImageViewer. I have been able to get this to work on Ubuntu 9.10. I followed instructions that I read from this mailing list and other related sites. But on OSX 10.6, I cannot get VTK to compile using Carbon or Cocoa. It always fails during the make process with the following error:<br>
<br>.../VTK/Examples/GUI/Qt/ImageViewer/main.cxx:36:24: error: QVTKWidget.h: No such file or directory<br>.../VTK/Examples/GUI/Qt/ImageViewer/main.cxx: In function ‘int main(int, char**)’:<br>.../VTK/Examples/GUI/Qt/ImageViewer/main.cxx:42: error: ‘QVTKWidget’ was not declared in this scope<br>
.../VTK/Examples/GUI/Qt/ImageViewer/main.cxx:42: error: expected `;' before ‘widget’<br>.../VTK/Examples/GUI/Qt/ImageViewer/main.cxx:43: error: ‘widget’ was not declared in this scope<br><br>However QVTKWidget.h is located /usr/local/include/vtk-5.4/QVTKWidget.h. What has gone wrong here?<br>
<br>Also, on Windows XP SP3, no matter what I try, Cmake reports "Qt was not found." However, it is installed. And I have manually created the QTDIR environment variable which points to 'C:/Qt/2010.01/'. I have also indicated that I am using version 4 (with DESIRED_QT_VERSION). And I can successfully develop a QT stand-alone app with this environment.<br>
<br>Any help or guidance would be greatly appreciated!<br><br>Caleb<br>
