Hi,
Is there a way to disable the download step ? Since we are using a vtk 8.0.1, we are now getting “HTTP response code said error” errors during the ExternalData downloading step.
I have set these two variables but i’m still getting errors.
PARAVIEW\_DATA\_EXCLUDE\_FROM\_ALL:BOOL=ON
VTK\_DATA\_EXCLUDE\_FROM\_ALL:BOOL=ON
thank you

Do you have any recommendations, @brad.king?

FWIW the last URL that reported `Couldn't connect to server` does exist [here](http://www.vtk.org/files/ExternalData/MD5/f291b9b218880e4b880bc1416ecda74e). CMake should know how to follow the http-to-https redirect during download. The download should succeed.
One could turn off `BUILD_TESTING` completely to avoid getting any test data downloaded.
According to local testing, `VTK_DATA_EXCLUDE_FROM_ALL` and `PARAVIEW_DATA_EXCLUDE_FROM_ALL` exclude dependencies on the `VTKData` and `ParaViewData` targets except from some source packaging targets. I’d need more information about how to reproduce the problem to help further:
- With what version of ParaView did you try to use VTK 8.0.1? How was the source tree prepared?
- What “cmake” command line was used to generate the build tree?
- What build command (e.g. “make”) was used to build it?

Hi,
We are using Paraview 5.3 with VTK 8.0.1
cmake -G Ninja
-DPARAVIEW\_ENABLE\_CATALYST=OFF
-DITK\_DIR=/home/buildbot/itk/build
-DOPENGL\_gl\_LIBRARY=/home/buildbot/local/lib/libGL.so
-DModule\_vtkIOPLY=ON
-DPARAVIEW\_QT\_VERSION=5
-DOPENGL\_INCLUDE\_DIR=/home/buildbot/local/include
-DCTEST\_USE\_LAUNCHERS=TRUE
-DOSMESA\_LIBRARY=/home/buildbot/local/lib/libOSMesa.so
-DCMAKE\_BUILD\_TYPE=Release
-DVTK\_USE\_X=ON
-DBUILD\_TESTING=ON
-DVTK\_OPENGL\_HAS\_OSMESA=ON
-DBUILD\_SHARED\_LIBS=ON
-DPARAVIEW\_ENABLE\_PYTHON=ON
-DCTEST\_MODEL=Experimental
-DPARAVIEW\_ENABLE\_WEB=OFF
-DVTK\_USE\_OFFSCREEN=ON
-DOPENGL\_xmesa\_INCLUDE\_DIR:PATH=IGNORE
-DOPENGL\_glu\_LIBRARY:FILEPATH=IGNORE
-B/worker/project-Test/project\_build
-H/worker/project-Test/project
-DPARAVIEW\_DATA\_EXCLUDE\_FROM\_ALL:BOOL=ON
-DVTK\_DATA\_EXCLUDE\_FROM\_ALL:BOOL=ON
build command :
ctest -S /worker/project-Test/dashboard/dashboard.cmake -R Testproject ‘-DCTEST\_CMAKE\_GENERATOR=“Ninja”’ -DCTEST\_TEST\_TIMEOUT:STRING=250 -DCTEST\_SOURCE\_DIRECTORY:PATH=/worker/project-Test/project -DCTEST\_BINARY\_DIRECTORY:PATH=/worker/project-Test/project\_build -DCTEST\_MODEL:STRING=Experimental -DCTEST\_BUILD\_BUILDER\_NAME:STRING=project-Test -DCTEST\_BUILD\_NUMBER:STRING=377 -DCTEST\_SITE:STRING=projectDockerAWS -Dctest\_parallel\_level:STRING=24
I am currently moving my cmake configure/build/test logic to my dashboard cmake. I am trying to replicate the ParaView flow from open.cdash
I need the BUILD\_TESTING since I am testing our state file.
Is there a way to make the ExternalData step give a warning instead of producing an error. My temporary solution was to deactivate the download functions in paraview/cmake/ExternalData.cmake

Setting PARAVIEW\_DATA\_EXCLUDE\_FROM\_ALL:BOOL=ON worked for me yesterday.
