[vtkusers] [VTK] Creating an OS X bundle for a VTK example using Qt

Mon Dec 15 06:18:20 EST 2014

Hi there,
we are having some trouble when trying to create an OS X bundle of an
imaging software of our own that uses ITK, VTK and Qt.

We are using VTK 6.1.0 and Qt 5.3.2. And our OS X is Yosemite (10.10).

In order to track the problem down, we tried to generate such a bundle for
one of the examples of VTK that uses Qt: QtVTKRenderWindows.

The modified CMakeLists.txt is attached.

We found that there seems to be a bug filed in kitware's CMake project in
mantis [1]. It dates back to 2013. It seems to be still open.

I am posting below the errors we get when trying to run our *.app just in
case they are of any help.

Is this a problem strictly related to CMake, or either VTK or either Qt for
OS X platforms?

Does anybody know how to solve this issue?

Thank you,
JON HAITZ

When executing the *.app, the application crashes, and OS X's crash report
shows this message (this is just the beginning):

If we try to execute the *.app from the command line, the error displayed
reads:

LSOpenURLsWithRole() failed with error -10810 for the file
/Users/usuario/Desktop/QtVTKRenderWindows.app.
MAC0001-D:Desktop usuario$

This application failed to start because it could not find or load the Qt
platform plugin "cocoa".

Reinstalling the application may fix this problem.
