voxl-dfs-server failing to run

Lynn Koudsi

I installed the latest voxl-suite and system image 3.3, and I noticed that voxl-dfs-server is failing to run. I'm getting the following output:

yocto:/# opkg list-installed | grep opencl
opencl - 0.0.2
yocto:/# systemctl status voxl-dfs-server -l

yocto:/#

any thoughts as to what could be the problem?

Thanks

Hi Lynn,

That should be built in to system image 3.3 and shouldn't show up in opkg. Can you paste the output of voxl-version to make sure everything is set up properly. Additionally, you can check if the libraries exist manually in /usr/lib or /usr/lib64 by running:

yocto:/usr$ find | grep -i opencl

Seemed like a weird fluke... I reinstalled the system image + voxl suite this time from the install script, then removed the packages individually and reinstalled my built versions, and it worked...

Thank you though!
