Hi,

I've been trying to deploy VVPX4 and see some dependencies. I am using the VOXL Platform 3.8.0-0.7 and VOXL-Cross-2.1 docker image.
```
voxl-vision-px4-master $./deploy_to_voxl.sh 
searching for ADB device
checking VOXL for dpkg/opkg
opkg detected
voxl-vision-px4_1.2.0.ipk: 1 file pushed. 3.4 MB/s (105362 bytes in 0.029s)
Reinstalling voxl-vision-px4 (1.2.0) on root.
Configuring voxl-vision-px4.
Collected errors:
 * satisfy_dependencies_for: Cannot satisfy the following dependencies for voxl-vision-px4:
 * 	libmodal-pipe (>= 2.4.0) * 	libmodal-cv (>= 0.1.0) * 
DONE
```
Maybe I have to build the following in a specific directory but I am not sure which one:
```
$ mkdir cross-workspace
$ cd cross-workspace
$ voxl-docker -i voxl-cross:V1.9
voxl-cross:~$ git clone https://gitlab.com/voxl-public/voxl-sdk/core-libs/libmodal-json.git
voxl-cross:~$ cd libmodal-json/
voxl-cross:~$ ./build.sh qrb5165
```
Can I install or source these two dependencies separately?

Yes you could, or you can install via our package management feed.  Here's the two packages from there from SDK 0.8:

http://voxl-packages.modalai.com/dists/apq8096/sdk-0.8/binary-arm64/libmodal-cv_0.1.0.ipk
http://voxl-packages.modalai.com/dists/apq8096/sdk-0.8/binary-arm64/libmodal-pipe_2.4.0.ipk

Depending on your setup, you could also install the VOXL-SDK fully and then modify parts you need from source.   More info here: https://docs.modalai.com/voxl-sdk/

Thank you @modaltb.

I'm having trouble deploying VVPX4 to to VOXL. The dependencies not being satisfied are being installed so I'm not sure what to do.

Here is what I'm doing:

```

After this, the package I am trying to deploy isn't on VOXL and the voxl-vision-px4 is enabled but not running.

Any pointers to what I may be missing?

Hi,

The install build deps script installs the dependencies to your docker image for building, not onto the voxl. If you're building packages with recent dependencies you'll need to update your voxl with ```opkg update``` to make sure it has the latest dependencies.

@Alex-Gardner Got it. Thank you!
