<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Hmmm. The most likely culprit would be that the loader cannot find all the dependent libraries for the plugin. What does otool –L report are the dependent libraries for the plugin. (Make sure you are using the same environment ParaView is run in.)<BR>

I have recompiled Paraview with the Debug flag specified (the same for the plugin), and I am sure I am launching the appropriate Paraview compilation. I obtain the following error:<BR>
<BR>
QLibrary::loady_sys:Cannot load libMergeTimeStepsSMPlugin<BR>
<BR>
During compilation, I receive a Warning about the fact that I am using Qt 4.4<BR>

Are you running the ParaView you compiled from scratch or the binary you downloaded? It probably will not work to try to load the plugin into the distribured binary.<BR>
<BR>
If you cannot load the plugin into the ParaView you compiled from scratch, try compiling both ParaView and the plugin with the CMAKE_BUILD_TYPE CMake variable set to Debug.<BR>

<BR>
thanks very much for your help. I am on Mac OS X Leopard on Intel. I did not know how to add a new filter to Paraview, and here is what I have done<BR>
<BR>
1) I have compiled Paraview from scratch<BR>
2) I have run ccmake and then make on the filter you gave me<BR>
3) I have now a libMergeTimeStepsSMPlugin.dylib<BR>
<BR>
I open Paraview and try to load the new plugin via the plugin manager. I receive the error message "The file libMergeTimeStepsSMPlugin.dylib" is not a valid Qt plugin. I am using Qt 4.4 <BR>
<BR>
Do you know what should I do?<BR>
<BR>
Best.<BR>

I also implemented a very simple filter to merge the time steps like you want. The source, complete with plugin, is attached to this message. The attachment may or may not make it to the paraview users’ list.<BR>
