As you can see it is an OpenGL linking problem. All these are openGL functions. So you must link with the OPENGL32.LIB and GLU32.LIB or whatever is relevant for your particular platform.<br><br>Let me know if that worked out for you.

Thanks Anja. <br>As per your suggestion I linked to other libraries but was still getting errors, so I linked to all the libraries. I am still getting errors. I am attaching the log file again here. Plz. let me know if you can figure it out.

Ok, it is pretty clear that you need to link to other vtk libs as well..<br>
<br>
This line:<br>
<span><span><span>LIBS += C:\vtk-5.0.2\VTKBINARIES\bin\debug\vtkRendering.lib
<br>
<br></span>
You need to add additional libs here...<br>
<br>
For example, vtkDICOMparser lib, vtkCommon lib etc. See the list that I had and take out the libs you do not need.<br>
<br>
This can be specified in your PRO file and qmake should generate the
proper studio file for you. I do not use windows, so I do not know the
exact details there.... At least you got rid of compiling errors,
linking should just be a matter of locating the right libs.<br>
<br>
Good luck,<br>

I ran a simple example. I clubbed the hello world example from qt and an image display example from vtk together and then ran it using qmake. I wanted to make a visual studio project so i ran the command:
<br>'qmake -project -t vcapp -o <a href="http://helloworld.pro" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">helloworld.pro'</a><br>this gave me a <a href="http://helloworld.pro" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
helloworld.pro</a> file. I edited this file to include the path etc and then ran qmake again. this gave me a .vcproj file which i opened in visual studio and then build it there. Here I got all those errors.
<br>The code I am using to test the working of vtk and qt together is as follows:<br>-----<br>#include <QApplication><br>#include <QPushButton><br>#include "vtkRenderWindow.h"<br>#include "vtkRenderer.h
"<br>#include "conio.h"<br>#include "vtkDICOMImageReader.h"<br>#include "vtkImageViewer2.h"<br>#include "vtkRenderWindowInteractor.h"<br><br><br> int main(int argc, char *argv[])
<br> {<br> QApplication app(argc, argv);<br><br> QPushButton hello("Hello world!");<br> hello.resize(100, 30);<br><br> hello.show();<br> // return app.exec();<br> // }<br>
<br>
<br>//int main( int argc, char *argv[] )<br>//{<br> <br> vtkDICOMImageReader *img1=vtkDICOMImageReader::New();<br> img1->SetFileName("D:\\testimages\\IM_00001.dcm");<br> <br> vtkImageViewer2 * myviewer=vtkImageViewer2::New();

Hi Ashish,<br><br>LD_LIBRARY_PATH only tells where to look for the dynamic libraries (DLLs on windows). <br><br>What development environment are you using? Did you simply run qmake on your pro file and then make or are you using an IDE?

Thanks Anja. But I am still stuck. Can you send me a simple example maybe a cone example with something like a push button along with the pro file, using both vtk and qt?<br><br>As you suggested I set the lib path in the .pro file and the include path to my vtk parent directory. But now it says cannot open include file
vtkconesource.h, if I add the path to this file it comes up with another file...and another and another...<br>I get 5-6 such errors and if I include the path to all of them, I get a fatal error:363 unresolved externals.<br>
What did i miss? what is the LD_LIBRARY_PATH in your example? I didnt do that part.<div><span><br><br>Thanks,<br>Ashish<br><br><br><div><span class="gmail_quote">On 10/13/06, <b class="gmail_sendername">

export QTDIR=/usr/local/Trolltech/Qt-4.1.4<br>
export QTDIR<br>
