Re: [Paraview] ParaView can't create the reader

First of all, your English looks pretty good!

OK, let's see if I can address all of the issues:

1. Make sure you downloaded the 3 files that were needed for installing
Qt 4.8.2, namely the file "qt-win64-opensource-4.8.2-vs2008.exe" and
the two associated "*.bin" files. The 3 files should be placed in
the same folder before running the installer.
2. In CMake, define the variable "QT_MAKE_EXECUTABLE" to use the path
"C:/Qt/4.8.2_x64/bin/qmake.exe" (adjust accordingly if necessary)
and then click on "Configure" once again. Hopefully it will now pick
up everything related to Qt.
1. Mmm... still regarding this point, if you in fact gave the
correct path, it might not work properly if the Qt installation
is somehow incomplete. This happened to me when I tried to
configure the project with CMake, while I was still midway of
the installation of Qt.
2. Furthermore, there was a detail I forgot to write on the wiki
page, but when using MSVC 2008 Express, by default it does not
provide the ability to compile 64-bit applications. Instructions
on how to do so can be found online, for example here:

https://github.com/enGits/engrid/wiki/Configure-Microsoft-Visual-Studio-2008-Express-to-also-build-for-Windows-x64
3. And there is yet another import detail: when you configure the
project in CMake's GUI for the first time, it asks you which
compiler to use. Make sure you pick "Visual Studio 9 2008
Win64". If you pick the standard non-Win64, it's natural that
the 64-bit "qmake.exe" is incompatible with the 32-bit Visual
Studio build options.
3. Regarding the files you've provided in attachment:
1. The XML looks OK. I only have some experience with creating
these types of XML file, so I'm not yet able to point out any
major flaws without looking into ParaView's own XML
filter/reader files. The complete XML file I'm referring to is
in the folder
"ParaViewCore\ServerManager\SMApplication\Resources" in
ParaView's source code.
2. The "CMakeLists.txt" looks OK as well, but again, I don't have
enough experience on this. Only by trial and error would I be
able to see if your file is working properly.
3. I suggest that you first try building the plug-in
"vtkPOFFReader", just to confirm if you have a working building
environment. This way it'll be easier to isolate the origin of
any problems.
4. "I have Visual C++ Express 2008 on my computer so is it normal to
get this message ?"*/
/*
* Yes, it's normal. It happens to me as well and it works without
any problems.
5. Due to how ParaView was built in this case, I think it's best to use
Qt 4.8.2 (namely with the respective architecture), just in case. I
say this because there are a lot of library dependencies that are
automatically configured and it might get a bit complicated to push
aside the existing dependencies on Qt.

I hope I didn't miss anything.

Best regards,
Bruno

Thank you very much for your answer.
I am sorry for my awful English and I hope you'll understand what I amwriting.
I read the email you sent and I tried to build my reader following theinstructions provided here :https://code.google.com/p/unofficial-paraview-dev-install/wiki/vtkPOFFReaderBuilds
First of all, I downloaded this archive :ParaView-4.1.0-win64-complete_dev-r2.exe<http://sourceforge.net/projects/bluecfd-sc/files/unofficial-paraview-dev-install/ParaView-4.1.0/ParaView-4.1.0-win64-complete_dev-r2.exe/download>Then I installed Qt 4.8.2 from here :https://code.google.com/p/qt-msvc-installer/. Finally when I am tryingto configure my reader with the CMake GUI, the QT_MAKE_EXECUTABLEcan't be found even if I select qmake.exe directly from the path.
In fact I am a beginner and I don't really know how to use CMake. Imodified the CMakeLists.txt that I found here :http://sourceforge.net/p/of-interfaces/code/HEAD/tree/trunk/vtkPOFFReader/but I am not sure about what I wrote. My CMakeLists file is joinedwith this message.
Besides, I noticed that when I am executing/qt-win64-opensource-4.8.2-vs2008.exe, /a dialog box with thefollowing message is opened :
/A installation of Visual Studio 2008 was not found in the registry ,guessing path.../
In spite of that, the installation seems to work perfectly fine but :I have Visual C++ Express 2008 on my computer so is it normal to getthis message ?
To finish, I would like to ask you one last question :
Given I didn't develop any GUI feature for my reader, do I still need QT ?

I thank you again for your help.

    Greetings Jérémy,

    If you had provided the XML file, it would have been a bit easier
    to diagnose this ourselves.
    Nonetheless, it seems to me that the issue is that the
    class/library "vtkPTecplotBinaryReader" is simply not loadable. A
    bit of searching online and in ParaView's source code leads me to
    believe that only the class "vtkTecplotReader" is available for
    loading through an XML only plug-in.

    If the class "vtkPTecplotBinaryReader" is a custom library you've
    built/created from source code, then have a look at a recent email
    I sent to this very same mailing list:
    http://public.kitware.com/pipermail/paraview/2014-August/031817.html

    Best regards,
    Bruno

    Hello,

    I have written my own reader for ParaView and I am facing with
    some issues.

    My version of ParaView is 4.1 for Windows-64 bit and I didn't
    build it from sources.

    As the wiki
    <http://www.paraview.org/Wiki/ParaView/Plugin_HowTo#Adding_a_Reader>
    describes, I wrote a Server Manager XML file.
    Then I set the environment flag PV_PLUGIN_DEBUG.

    Everything seems to work fine when I load the reader with Plugin
    Manager as the output messages dialog box indicates :

    ***************************************************

    Attempting to load
    
C:\Users\Windows\Documents\Travail\ParaviewProject\VTKReaders\Plugin\TecplotBinaryReader.xml

    Loading XML plugin

    Plugin instance located successfully. Now loading components from
    the plugin instance based on the interfaces it implements.

    ----------------------------------------------------------------

    Plugin Information:

    Name : TecplotBinaryReader

    Version : 1.0

    ReqOnServer : 1

    ReqOnClient : 0

    ReqPlugins :

    ServerManager Plugin : Yes

    Python Plugin : No


    But when I try to open a file, ParaView crashes and I get the
    following error message :

    ERROR: In
    
C:\DBD\pvs-x64\paraview\src\paraview\ParaViewCore\ServerImplementation\Core\vtkSIProxy.cxx,
    line 307

    vtkSISourceProxy (000000000B340ED0): Failed to create
    vtkPTecplotBinaryReader. Aborting for debugging purposes.


    What am I doing wrong ?


    Thanks in advance for your help.


    Jérémy
