Paraview v4 compilation

Hey guys,

Concerning building paraview version 4.0 (3.98 included), etc [tested with OpenFOAM-2.2.x]. A few lines of codes need to be updated. Today, after a few tries, I found the following modifications seem to work for me, I hope it helps!

1. Make sure you turn on "PARAVIEW_INSTALL_DEVELOPMENT_FILES ON" before you build paraview. (otherwise you won't have header files installed)

2. In file "vtkPV3FoamReader.h" and "vtkPV3blockMeshReader.h", change VTK_IO_EXPORT to VTK_EXPORT

3. In file "vtkPV3FoamReader.cxx" (~ line 314)

Code:

    for (int infoI = 0; infoI < nInfo; ++infoI)

    {

        vtkInformation *outInfo = outputVector->GetInformationObject(infoI);



        if

        (

            outInfo->Has

            (

                vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEP()

            )

         && outInfo->Length

            (

                vtkStreamingDemandDrivenPipeline::TIME_STEPS()

            ) >= 1

        )

        {

            requestTime[nRequestTime++] = outInfo->Get

            (

                vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEP()

            );

        }

    }

Another thing I found last friday is that the Ubuntu-13.10, at least till to now, comes with paraview-4.x, qt-5.x and vtk-5. VTK-5 is not a problem, but if you are building with VTK-6, it seems that paraview does not support it yet. And also since the default qt version is qt5 for Ubuntu-13.10, so Qt in paraview build script should be set to use qt-4, that using qmake-qt4 instead of the default /usr/bin/qmake, when you are building your own paraview. But even so, there is still some problems that won't go through. So I finally find out why not just use the system paraview-4.x without building paraview yourself? Everything looks fine.
[*] By saying system, I mean you can download through apt-get.

Hi Daniel,

A few notes:

AFAIK, ParaView usually builds with its own branch of VTK and rarely works with the system's VTK version :(.
- One example is that as of ParaView 3.98.0, it has been built with beta versions of VTK 6. When ParaView 4.0.1 was released, VTK 6.0.0 hadn't been released yet.
- Another example - you won't find a specific indication of which VTK version it's using: http://paraview.org/Wiki/ParaView/Binaries
- There was a mail sometime ago in the ParaView mailing list from Debian maintainers asking for cooperation for consolidating VTK versions with ParaView versions, at least to avoid collision of library files: http://markmail.org/message/pujxu6d526albnx2
VTK 6.0 does not support Qt 5, therefore neither does ParaView 4.0.

Best regards,
Bruno

Thanks for the clarification. Are you hard-working on Sunday? :D I thought paraview and vtk are from the same team.
