So I've bought a HDK2 for use on Linux and as you may know, the SteamVR support for Linux is just bad right now.

First, I had some problems with the packaged Qt:

ViveRenderer::Initialize() - VR_IsHmdPresent() returned false
QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled

Thread 1 "janusvr" received signal SIGSEGV, Segmentation fault.
0x00007ffff35935c8 in QOpenGLContext::format() const () from /opt/janusvr/libs/libQt5Gui.so.5
(gdb) bt

#5  0x0000000000422437 in main ()

after removing libs/libQt5* I there was this problem:

libGL: dlopen /usr/lib/xorg/modules/dri/radeonsi_dri.so failed (/opt/janusvr/libs/libstdc  .so.6: version `GLIBCXX_3.4.22' not found (required by /usr/lib/libLLVM-4.0svn.so))

You really shouldn't have to package libstdc .so.6. Every linux system you care about supporting already has a copy of that library and unless you're using a libstdc from a time when c 11 was experimental and used those experimental features (I heard that is the only way it could cause trouble), it should be perfectly backwards compatible. And people on the exotic linux systems who don't have it most likely already know how to install it.

So after removing libstdc .so.6 too janusvr -render vive seems to mostly work. SteamVR loads the OSVR stuff, it opens a fullscreen window, but it's "transparent" and doesn't display anything. Also no sound. And after a couple of seconds it segfaults:

Core was generated by `./janusvr -render vive'.
Program terminated with signal SIGSEGV, Segmentation fault.

apparently the stack is corrupted.

Tl;dr: SteamVR on Linux doesn't work well. Have you considered native OSVR support?
