Hello,

I am trying to build paraview for Windows (that is because I am getting a version mismatch when I try to connect to my ubuntu server).

I am following this tutorial:

[https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md](https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md)

It I try to do the cmake with:

`cmake -GNinja -DPARAVIEW_USE_PYTHON=ON -DPARAVIEW_USE_MPI=ON -DVTK_SMP_IMPLEMENTATION_TYPE=OpenMP -DCMAKE_BUILD_TYPE=Release ..\pv`

or with CMake GUI v3.19.0

I am getting this error:

– Performing Test HAVE\_GCC\_ERROR\_RETURN\_TYPE  
– Performing Test HAVE\_GCC\_ERROR\_RETURN\_TYPE - Success  
CMake Error at C:/Program Files/CMake/share/cmake-3.19/Modules/CheckSourceRuns.cmake:122 (message):  
Unknown argument:

```
Support for 64 bit file systems

```

Call Stack (most recent call first):  
C:/Program Files/CMake/share/cmake-3.19/Modules/CheckCXXSourceRuns.cmake:71 (check\_source\_runs)  
CMakeLists.txt:123 (check\_cxx\_source\_runs)

– Configuring incomplete, errors occurred!

Can you please help me?

Thanks,

Francesc

Make sure you are using all 64 bit compilation tools and third parties.

eg, are you using the Native **x64** command ?

Thanks Mathieu,

How do I specify compiler and platform?

In this call:

`cmake -GNinja -DPARAVIEW_USE_PYTHON=ON -DPARAVIEW_USE_MPI=ON -DVTK_SMP_IMPLEMENTATION_TYPE=OpenMP -DCMAKE_BUILD_TYPE=Release ..\pv`

I want to set sth like:

`cmake -G "Visual Studio 14 2015" -A x64`

but it does not work.

Well, building ParaView on windows using visual studio does work, but it is not tested, hence we can’t recommend it.

To do that, just use cmake-gui.

I am not stubborn in building Paraview using Visual Studio. I just want to follow your tutorial to build Paraview for windows as per:

[https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md#windows](https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md#windows)

I will be happy if I can build Paraview for Windows with any toolset. What should I do?

FYI, I’m seeing the same error on Ubuntu 18.04 using gcc 8 with ParaView master and CMake 3.19.0-rc1. VTK builds fine. Hope it helps to reproduce.

The problem turned out to be a regression in 3.19.0-rc1 (which I have a fix for) and I have a fix in ParaView to make it not care anyways.

Discussion is [here](https://discourse.paraview.org/t/cmake-unknown-argument-support-for-64-bit-file-systems-on-ubuntu-18-04/5646).
