Any idea why this happen? opentrack: error while loading shared libraries: opentrack-user-interface.so: cannot open shared object file: No such file or directory This can be migrate by launch it via root Maybe fault of fakeboot?

The newer version seems to work fine for me

I'll just leave this message here for those people that may be struggling with making the neuralnet tracker work.

While having onnxruntime in the dependencies is definitely needed for the neuralnet tracker to work, it wasn't enough for me - the tracker just wouldn't appear.

I resorted to compiling OpenTrack manually. I was basing my steps on the official developers' instructions for Manjaro provided here: https://github.com/opentrack/opentrack/wiki/Building-on-Linux

Unfortunately, the tracker wouldn't appear then either, even with the manual compilation.

After digging in the build files of the tracker a bit and re-enabling some of the verbose output, I saw error messages claiming that it fails to find the onnxruntime includes location. Therefore, the cmake ended up excluding the tracker from the build.

I therefore fixed it by manually specifying the ONNXRuntime location variables on the corresponding step of the official instrucitons where "cmake .." is supposed to be run. Instead, I ran a more detailed command like this:

cmake -DONNXRuntime_DIR=/usr/lib/cmake/onnxruntime -DONNXRuntime_INCLUDE_DIR=/usr/include/onnxruntime ..

If this problem is present in the AUR package version, I suspect that the cause is similar - most likely, cmake simply fails to find the ONNX package files it needs.

mentioned back in 2021 by Reezlaw, it would be great to include the other tracks, in particular the Aruco tracker.

@rbuchberger I just had to explicitly install libprocps for it to begin to work. Neither having procps-ng installed nor editing the PKGBUILD to include it as a dependency were sufficient for me.

But I still get a failed build with these messages:

[132/482] Generating opentrack-wrapper-wine.exe.so
FAILED: proto-wine/opentrack-wrapper-wine.exe.so

ninja: build stopped: subcommand failed.
==> ERROR: A failure occurred in build().
    Aborting...
 -> error making: opentrack-exit status 4
 -> Failed to install the following packages. Manual intervention is required:
opentrack - exit status 4

makedepends appears to be missing procps-ng.

Builds fail for me with this message: Can't find 'libprocps'. Please install development files for this package.

Moofed - would you please add it?

Everyone else with the same issue - Edit the PKGBUILD to add it yourself, and your build should succeed again.

You may want to add onnxruntime AUR package as an opt depends, it should allow opentrack "neuralnet-tracker" (webcam AI face tracking)

Is there supposed to be an xplane output plugin?

Since the current Manjaro AUR version doesn't show a camera image, you can compile opentrack from source with these instructions. Took me some time to figure it out. Hope it helps others to get Opentrack running again.

Install Dependencies

• or -

git clone https://github.com/opentrack/opentrack

cd opentrack/

mkdir build

make

make install

cd install

cd bin

./opentrack

Video input stopped working with the latest AUR version (opentrack 2021.1.2-1) even though the camera is being detected and works with V4L2. Can the maintainer please update the AUR version to the latest Github version?
