Okay, that's clear, and now works. Thanks for your help.<br>
<br>
I'm now off to try to replicate the same success on Linux and Windows...<br>

You need to run "install_name_tool" or set up your build so that your
plugin references the Qt shared library with the same name as ParaView.

Global qt state is not really global if you have two sets of qt shared
libraries loading.<br>

Does it
contain "@executable_path/../Frameworks/QtGui.framework/Versions/4/QtGui" or
something else?
On the Mac, if its something else, you're going to get two instances of QtGui
in the application.

which is what I used to build Paraview and my plugin. I built the
Paraview 3.1 source, built my plugin against it, and am subsequently
trying to load the plugin with the released 3.1 executable.
No luck yet. I'll report back if I find my way.
Thanks,

Its possible to have a NULL qApp if a different version of Qt is used
when building the plugin.
I'd probably check in the debugger (even in release mode) what libraries
are actually being used, after your plugin loads.

and it works fine with the Paraview executable I've built. I'd like for
it to also work with the official Paraview releases, but in that case
Paraview crashes trying to load the plugin.
That's because the plugin code makes a call against qApp (as does the
Paraview plugin example), but qApp is NULL. So my questions are:
- Is there a related build dependency that I need to consider? (I've
already ensured that my plugin uses CMAKE_BUILD_TYPE=='release')
- Should I be able to successfully build plugins for loading by the
release code? (I expect that's the long term plan, but wonder if it is
not yet possible.)
Any help would be appreciated.
Thanks,
Tom
