[vtkusers] VTK with OpenVR on Linux (HTC Vive)

Wed Oct 17 08:02:17 EDT 2018

Dear Ken,

I did as you requested.
In 2D, it works just fine, but when including the vtkOpenVR headers, it cannot build anymore.
The make error message while linking is the same as before.
This is the modified code file: https://pastebin.com/NDk2kzhc (https://pastebin.com/NDk2kzhc)
And the modified CMakeLists: https://pastebin.com/Gs9szZGc (https://pastebin.com/Gs9szZGc)
(This builds and runs with the old vtk version)

Make error message:

Maybe try starting with something like this 
https://lorensen.github.io/VTKExamples/site/Cxx/GeometricObjects/Cylinder/ (https://lorensen.github.io/VTKExamples/site/Cxx/GeometricObjects/Cylinder/) 
Get that built and running on your system. Then edit that to add in the openvr codes.

Dear Ken,
Unfortunately, this still doesn't work on the current master(pulled some minutes ago). This is my current CMakeLists.txt: https://pastebin.com/J2UyX6tr (https://pastebin.com/J2UyX6tr)

The error looks pretty much the same as before:

Here you can find the verbose make output: https://pastebin.com/uKkPwWJP (https://pastebin.com/uKkPwWJP)

What is AutoInit?

Do you have another idea what to try?

Best wishes,

Maybe try something like the following in your CMakeLists. It works for me without adding any autoinit stuff. 
find_package(VTK REQUIRED)
vtk_module_config(VTK
vtkCommonCore
vtkCommonDataModel
vtkFiltersGeneral
vtkIOImage
vtkIOXML
vtkInteractionStyle
vtkRenderingOpenGL2
vtkRenderingOpenVR
)
include(${VTK_USE_FILE})

Dear Ken,
I tried to paste those lines in like that: https://pastebin.com/SRmt1GNp (https://pastebin.com/SRmt1GNp)

More fixing seems to be needed, as I am getting a very similar (but longer) linker error message:

You may need 
#include "vtkAutoInit.h"
VTK_MODULE_INIT(vtkRenderingOpenGL2) 
VTK_MODULE_INIT(vtkRenderingOpenVR) 
or similar. Give that a shot - Ken

	Dear Ken,
I finally managed to get my code building and running on both Windows and Linux.
You can find it here:
https://transfer.sh/gJ1Sg/vtkOpenVRHelloWorld.zip (https://transfer.sh/gJ1Sg/vtkOpenVRHelloWorld.zip)

Unfortunately, it doesn't work with the latest VTK-Version from https://gitlab.kitware.com/vtk/vtk (https://gitlab.kitware.com/vtk/vtk)
After some testing, I found the first commit it doesn't build with: https://gitlab.kitware.com/vtk/vtk/commit/61bc6b5b4b8f0d2d111f6c10af3dd79488f919cc (https://gitlab.kitware.com/vtk/vtk/commit/61bc6b5b4b8f0d2d111f6c10af3dd79488f919cc)
(VTK builds, but my program doesn't build with this VTK Version)

Even though I already use the vtkOpenVR* classes explicitly, it doesn't build.
Is there something else I have to change to make it compatible?

Make produces the following Linker error:

[ 50%] Linking CXX executable vtkOpenVRHelloWorld
CMakeFiles/vtkOpenVRHelloWorld.dir/CylinderRenderingProperties.cxx.o: In function `vtkRenderingOpenGL2_AutoInit::vtkRenderingOpenGL2_AutoInit()':

Any help would be appreciated!

You need to create an use an OpenVRCamera. From your code it doesn't look like you are. I doubt that is the crash but it could be. 
Does the example work on windows? Since linux is an unknown I would think it would be best to make sure you have something working on windows, then port to linux.

Hey Guys,
Has anyone of you been able to use the vtkOpenVR classes on Linux?
I can run Steam with SteamVR on a Ubuntu 18.04 system, but when I try to run the HelloWorld Example of VTK modified for VR, I encounter a segmentation fault.
You can find the code I used here: https://pastebin.com/gjsvKy58 (https://pastebin.com/gjsvKy58)
The whole project with binary and core dump can be found here: https://transfer.sh/6vONY/build.zip (https://transfer.sh/6vONY/build.zip)

Do you have any suggestions on how to get this working?

Thanks in advance!
