Unable to Use #32 on Linux

[georgewsinger]

I'm running Arch Linux:

$ cd ~
$ git clone --recursive https://github.com/OSVR/OSVR-Vive.git
$ cd OSVR-Vive
$ git pull origin pull/32/head
$ mkdir build
$ cd build
$ cmake ..
$ make

This yields the following build error:

Hi George, I think that submodules have not updated after you pulled the openvr108 branch. The errors are indicating that it cannot find code that is present in the latest OpenVR SDK. Please run git submodule update --recursive and give it one more try.

[georgewsinger]

Yes -- that worked.

Running the newly compiled ViveDisplayExtractor yields [DisplayExtractor] Error in first-stage Vive driver startup. Exiting. I'm re-downloading SteamVR though which I think might fix this.

[georgewsinger]

Update: Still Unable to Use #32 on Linux

Running Arch Linux (with SteamVR fully updated and launchable), I successfully compiled #32, and then symlinked /usr/lib/osvr-plugins-0/com_osvr_Vive.so to the com_osvr_Vive.so generated from the build:

$ cd /usr/lib/osvr-plugins0
$ ls -l com_osvr_Vive.so
com_osvr_Vive.so -> /home/george/OSVR-Vive/build/lib/osvr-plugins-0/com_osvr_Vive.so

however, I am unable to get ViveDisplayExtractor to work:

$ ViveDisplayExtractor
[DisplayExtractor] Error in first-stage Vive driver startup. Exiting

After ignoring this and assembling an OSVR config from the OSVR-Vive repo, I get a "could not open driver" message:

Video-based tracker: Windows users may need to exit other camera-using applications or activities until after the tracking camera is turned on by this plugin. (This is the most common cause of messages regarding the 'filter graph')

Still, same error as yours

[ChristophHaag]

@georgewsinger

June 17 10:42:43.750 error [createRenderManager]: OpenGL/Direct3D Interop not compiled in

You're probably using a rendermanager config with direct mode enabled. In osvr_server_config.vive.sample.json you can just use the standard extended mode config:

"renderManagerConfig": "/usr/share/osvrcore/sample-configs/renderManager.extended.landscape.json"

[georgewsinger]

@ChristophHaag I can confirm changing to extended mode allows, i.e., RenderManagerOpenGLCoreExample to launch, however there is no tracking present (neither with the headset nor the Vive controllers). In addition, OSVRTrackerView continues to show no tracked objects (neither HMDs nor controllers).

[ChristophHaag]

Yes, your vive plugin prints

June 17 10:42:01.701 info [OSVR-Vive]: Could not open driver.

It should do this before the block that prints "Could not open driver":

if (vive.foundDriver()) {
    std::cout << PREFIX << "Found the Vive driver at "
              << vive.getDriverFileLocation() << std::endl;
}

so for some reason it doesn't find the Vive driver. For me it prints

June 17 17:39:34.561 info [OSVR-Vive]: Found the Vive driver at /home/chris/.local/share/Steam/SteamApps/common/SteamVR/drivers/lighthouse/bin/linux64/driver_lighthouse.so

It's probably looking in the path specified in ~/.openvr/openvrpaths.vrpath

[georgewsinger]

@ChristophHaag : Can you post the contents of your ~/.openvr/openvrpaths.vrpath for comparison?

Here is mine:

{
    "runtime" : [ "/home/george/.local/share/Steam/SteamApps/common/SteamVR" ],
    "config" : [ "/home/george/.local/share/Steam/config" ],
    "log" : [ "/home/george/.local/share/Steam/logs" ]
}

[ChristophHaag]

It's this one: https://haagch.frickel.club/files/openvrpaths.vrpath.txt, looks just like yours.

If you have the file ~/.local/share/Steam/SteamApps/common/SteamVR/drivers/lighthouse/bin/linux64/driver_lighthouse.so and it looks okay then I don't know what the problem is.

[georgewsinger]

I can confirm that I also have ~/.local/share/Steam/SteamApps/common/SteamVR/drivers/lighthouse/bin/linux64/driver_lighthouse.so.

Weird.

[georgewsinger]

I also found ./home/george/.config/openvr/openvrpaths.vrpath that was somehow generated on my system (I wonder which one is read when launching osvr_server?); it has the following contents:

{
   "config" : [ "/home/george/.local/share/Steam/config" ],
   "external_drivers" : null,
   "jsonid" : "vrpathreg",
   "log" : [ "/home/george/.local/share/Steam/logs" ],
   "runtime" : [
      "/home/george/steamcmd/steamapps/common/SteamVR/",
      "/home/george/steamcmd/steamapps/common/SteamVR",
      "/home/george/.local/share/Steam/steamapps/common/SteamVR/",
      "/home/george/.local/share/Steam/steamapps/common/SteamVR"
   ],
   "version" : 1
}

However, after changing this to the usual contents reported above:

{
    "runtime" : [ "/home/george/.local/share/Steam/SteamApps/common/SteamVR" ],
    "config" : [ "/home/george/.local/share/Steam/config" ],
    "log" : [ "/home/george/.local/share/Steam/logs" ]
}

...the original "Could not open driver." error persists.

[ChristophHaag]

I was hoping someone from OSVR would know more about this. It looks like something there is going wrong and I would probably start investigating at these lines... https://github.com/OSVR/OSVR-Vive/blob/master/FindDriver.cpp#L217

[gfrolov]

@georgewsinger , Hmm, based on the error, it looks like there could be multiple things that are going wrong:

1. Config dir is not found
2. Driver file and/or driver directory is not found. However since you included that you have the driver file itself, then it could be a mix up due to an environment variable. What does your $HOME variable point to ? OSVR-Vive will use $HOME variable if it's available, but if it's not then it will use ~/.openvr/openvrpaths.vrpath, so I'd first check on that. If that looks good, then check if /home/george/.local/share/Steam/config exists.

[georgewsinger]

1. My $HOME directory is set to /home/george. So it seems that $HOME/.openvr/openvrpaths.vrpath is the same as ~/.openvr/openvrpaths.vrpath; its contents is

{
    "runtime" : [ "/home/george/.local/share/Steam/SteamApps/common/SteamVR" ],
    "config" : [ "/home/george/.local/share/Steam/config" ],
    "log" : [ "/home/george/.local/share/Steam/logs" ]
}

2. I can confirm that /home/george/.local/share/Steam/config exists:

Is there something else I could be missing?

[georgewsinger]

UPDATE: I've done a little bit of poking into the source code to try to figure out what's causing the driver to fail to be found. The problem with driver initialization can be superficially traced to DriverWrapper.h:

bool haveDriverLoaded() const {
        // only one of these pointers will ever be initialized at a time,
        // since we move from loader_ to initialize serverDeviceProvider_

        // loader_ has an explicit operator bool to check its success, hence
        // the longer check.
        return (static_cast<bool>(loader_) &&                //evalutes as "0" when printed
               static_cast<bool>(*loader_)) ||
               static_cast<bool>(serverDeviceProvider_); //evaluates as "0" when printed
}

As the comments indicate, both static_cast<bool>(loader_) and static_cast<bool>(serverDeviceProvider_) evaluate to 0 when printed. From there it's more opaque what's causing this. While I'm no C++ expert, I'm assuming this indicates an upstream failure having to do with loader_ and/or serverDeviceProvider_ (i.e., these pointers aren't pointing to anything).

I wonder if there's a way to print to the console what OSVR-Vive thinks my driver directory is?

[georgewsinger]

Thanks to @ChristophHaag helping me debug my system, it turns out that

$ cd /home/george/.local/share/Steam
$ ln -s steamapps SteamApps

solved the issue. That is, OSVR-Vive is expecting a folder called SteamApps, and yet on my system it was somehow being generated by steam as steamapps? Creating this symlink allows OSVR-Vive to successfully find the driver.

End result: I can now launch OSVR-Vive in direct mode and run OSVRTrackerViewer, which shows HTC Vive controllers + Headset being tracked. Running in extended mode yields the server error:

June 23 15:50:49.292 info [Settings]: GetBool doesn't contain the settingKey: fakeDigitalTrigger

and then causes a seg fault.

In direct mode, I still cannot launch, i.e., RenderManagerOpenGLCoreExample without getting the error:

June 23 15:48:37.097 error [createRenderManager]: OpenGL/Direct3D Interop not compiled in
Could not create RenderManager

So there's no way for me to run a test app with OSVR-Vive yet.

[ChristophHaag]

@georgewsinger Well.. in https://github.com/OSVR/OSVR-Vive/issues/33#issuecomment-309226384 you said your steam-generated openvrpaths.vrpath said

"runtime" : [
   "/home/george/steamcmd/steamapps/common/SteamVR/",
   "/home/george/steamcmd/steamapps/common/SteamVR",
   "/home/george/.local/share/Steam/steamapps/common/SteamVR/",
   "/home/george/.local/share/Steam/steamapps/common/SteamVR"
],

which apparently didn't work, so you changed it to

"runtime" : [ "/home/george/.local/share/Steam/SteamApps/common/SteamVR" ],

If you remove the symlink and try it with

"runtime" : [ "/home/george/.local/share/Steam/steamapps/common/SteamVR" ],

it could work too..

Anyway, https://github.com/OSVR/OSVR-Vive/issues/33#issuecomment-309223629 was probably wrong. Those case errors are insidious because of how easily you can fail to see them...

To any of the developers: It would be great if OSVR-Vive could output some debug info here, e.g. the file name it is trying to open and an error message when it fails.

[georgewsinger]

@ChristophHaag: You're right. The issue was a case error with my openvrpaths.vrpath the whole time.

[gfrolov]

@georgewsinger Do you still have this problem on Linux with the latest version or we can resolve the issue ?
