[Paraview] Not a valid QT plugin on windows

Tue Jan 6 03:12:07 EST 2009

Dear all,

I go further with this discussion : I have also a "not a valid Qt
plugin" error on windows.

The devel system is :
- Windows XP SP3
- ParaView 3.4 built with
   - Python 2.5
   - Qt 4.3.5
   - MS Visual C++ 9.0 Express

Qt is also built with Visual 9.0

The plugin compiles and works well on this system (but a weird
"STATIC" vs "SHARED" problem persists, that will be described in
another e-mail).

The user system is XP SP3 with the available ParaView 3.4 binaries.
When loading the plugin, I get a "Is not a valid Qt plugin"

I noted that the only difference between my compiled ParaView and the
available one is the IDE (Visual 9 express vs. Visual 2005 ). Is it
possible that this is the source of the error ? Unfortunately, I do
not have access to a VS 2005, so I cannot try...

Thanks for your time, and obviously : happy new year !

Regards,

Jerome
