Hi,

I download voxl-dfs-server from gitlab as a master.

Then I compiled as stable dependency. but failed on processing.

maybe opencl library is not included.

    swift@swift-HP-Pavilion-dv6-Notebook-PC:~/git/voxl-dfs-server$ voxl-docker -i voxl-cross
         launching image: voxl-cross with the following command:

1) could you please check?

2) also I want to see dfs image result using client pipeline as voxl-cam-logger.
It also cannot compiled on this version. 
could you please let me know to resolve it?

You need to use the latest version of voxl-docker from developer.modalai.com

## Reply by shlee853 · 2021-07-04 21:57:00 UTC

I downloaded latest sw in gitlab. as I know, ver.0.2.0 is latest one.

## Reply by Alex Kushleyev (ModalAI staff) · 2021-07-06 01:40:41 UTC

`voxl-emulator` and `voxl-cross` are docker images that contain the voxl system headers and libraries for cross-compilation (`voxl-cross` is used in this example). `voxl-docker` is a script which launches `voxl-cross` docker image. The docker image has been updated to include opencl stuff. Make sure you download the latest `voxl-emulator` and `voxl-cross` docker images from https://developer.modalai.com/asset.

@Alex-Kushleyev okay Thanks buddy

## Reply by shlee853 · 2021-07-12 08:39:17 UTC (in reply to Alex Kushleyev)

@Alex-Kushleyev Can I ask something?

Can I get disparity image in real-time using stereo camera?

obstable distance is not reliable on 0 degree for my voxl flight.

Thanks,

## Reply by Chad Sweet (ModalAI staff) · 2021-07-13 04:07:56 UTC

If the data is not very accurate, it is likely you need to recalibrate the stereo sensors. Instructions are [here](https://docs.modalai.com/calibrate-cameras/)

Otherwise, the data is published here [disparity](https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-dfs-server/-/blob/master/server/dfs_processing_engine.cpp#L684) and [point cloud](https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-dfs-server/-/blob/master/server/dfs_processing_engine.cpp#L721). We provide the code so you can change how you see fit for your application

## Reply by shlee853 · 2021-07-15 12:59:23 UTC (in reply to Chad Sweet)

@Chad-Sweet could you please try compile voxl-dfs-server 0.2.0 and client?

I need to modify application but it failed even the voxl-cross version is newest.

Thanks,

Hi shlee,

Here is a copy of my device cloning a fresh copy of dfs-server and building it successfully in voxl-cross, if you could let us know exactly what errors you're encountering when trying to build that'd be helpful.

@Alex-Gardner are you using a version 1.1 for voxl-cross?

You can find my compilation result at the first comment in this thread.

The errors are related with obsolete opencl lib.

Thanks

@Alex-Gardner Thanks for your supports.

I realized voxl-docker s/w was updated 1 month ago.

I resolved this problem using newest voxl-docker.
