[Paraview] How to create a vtkModule in Paraview

[michal wozniak]

Hi,


The .lib isn't created on Windows if we have no exports. To generate the .lib file, you will need to at least have one class in your module with a "VTK_EXPORT".

Just to make sure I am understanding the current state correctly, The vtkAddon<https://github.com/lorensen/vtkAddon/blob/master/module.cmake> module works fine, but your custom module doesn't. Is that correct? If so, may be you want share a stripped down version of the module so we can spot what's missing by building locally.

Hi Utkarsh,


I have tried adding the path to my external module via PARAVIEW_EXTERNAL_MODULE_ROOTS in cmake. I am able to compile the module in VS2015 but it only creates a .dll file. Usually, at least from what I've seen with the other modules, a library is also created which is needed to use the plugins in the modules. I have checked all the documentation and did a really simple module containing only a single plugin.


Here is an overview of what it looks like:


module.cmake:


vtk_module(vtkSPXModule
  GROUPS
    StandAlone
  DEPENDS
    vtkCommonCore
    vtkCommonDataModel
    vtkCommonExecutionModel
    vtkCommonMisc
    vtkPVVTKExtensionsRendering
    vtkFiltersGeneral
    TEST_DEPENDS
    vtkTestingCore
    KIT
    vtkRemote
  )



and the Cmakelist.txt:


set(Module_SRCS
  TestPlugin.cxx
  )


vtk_module_library(vtkSPXModule ${Module_SRCS})


I referred myself to this example that seemed to work https://github.com/lorensen/vtkAddon/blob/master/module.cmake


Overall, to make sure it's clear, I am able to compile the module and I'm able to see it in my solution. The problem is more so linked to the creation of the .lib that isn't being done. Any idea what could cause that?

Thank you,

Simon-Pierre

Simon,

While plugins can have internal modules, it's really not designed to share those with other plugins. You have two options:

1. combine both plugins into a single one.
2. make the module a standard ParaView/VTK module that added via PARAVIEW_EXTERNAL_MODULE_ROOTS CMake variable, then the two plugins can use the module just liek any other ParaView/VTK module.

Hi,

I created a custom plugin that I want to use in a second plugin. To do so, I want to create a module with the custom plugin to be able to use it in my second one.

I tried creating the module following the instructions on http://www.vtk.org/Wiki/VTK/Module_Development but it did not work.


Basically, I am able to compile my module and create a .dll with it but I can't seem to be able to create the .lib and .ext necessary.

I also added my module in the VTKModule.cmake. I'm unsure why it is not generating a .lib since I can see the line add_library in the cmake file generated for vtkmodules with my module name.


Could anyone try to help me figure out what I'm missing?


Thank you,


Simon-Pierre Desjardins




I'm compiling using Visual studio 2015 and Windows 10 64bits
