Linux support for KerbTrack and head tracking

[raath]

I've made a go at starting some kind of support going for head tracking on Linux with pizzaoverhead's KerbTrack but running into a few brick walls. I'm not a .net dev so if I'm making a total noob mistake please inform me.

I use LinuxTrack for head tracking in other games on Linux. This usually works via piping linuxtrack to a virtual joystick device (usually /dev/uinput) which I can then select as the head tracking input in most games.

I was looking at various .net libraries to pick up on joystick input and the only universal one that works on all OSes is OpenTK which I've downloaded and compiled. I've added a class to use the OpenTK framework but getting this error when trying to switch kerbtrack to it :

KerbTrack: Using OpenTKTrack

TypeLoadException: Could not load type 'OpenTK.Platform.Factory' from assembly 'OpenTK, Version=1.1.0.0, Culture=neutral, PublicKeyToken=bad199fe84eb3df4'.

I've compiled both OpenTK and KerbTrack in x86 and .net 3.5

My forked KerbTrack's last commit is here

Alternatively if there's an easier way of doing this then I'd be happy to look into that. Currently I have a work around going by assigning the Linuxtrack device to the Camera Horizontal and Vertical primary in settings -> Input -> Game but the input is relative so is there a way of altering this into an absolute value? That would allow proper head tracking.

How do you use Linuxtrack as a virtual joystick?

Figured it out:
