Toolchain problem ? VOXL-Vision-Hub fails to build

[tom]

@Hector-Gutierrez You don't want to be building for qrb5165-2, you want qrb5165

[tom]

@Hector-Gutierrez All of our packages get built on master and dev each night so if you're wondering whether the package is able to be built you can always check the status of the CI pipelines: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/pipelines

Tom - thanks for the prompt response. I used qrb5165-2 since I'm running on Ubuntu 20.04 and the build instructions mention to use that option.
I re-did the procedure (after deleting all files from the previous attempt) , this time I used qrb5165 for both dependencies and built. Build fails, several warning, build error very similar as before:

make: *** [Makefile:136: all] Error 2

I'm able to build other applications, so it seems my voxl-docker and voxl-cross are working properly. Please advise on what else could I try.
Thanks, Hector

@Hector-Gutierrez What branch are you trying to build? If you install dependencies from the dev repo then you should also be building the dev branch of voxl-vision-hub

[tom]

@Hector-Gutierrez Your VOXL2 is running Ubuntu 20 or your host machine is Ubuntu 20?

We don't build voxl-vision-hub for ubuntu 20 so that isn't correct

[tom]

@tom I believe we're also still building voxl-vision-hub with voxl-cross:V2.7, we're in a bit of a transition period of moving packages to the newer voxl-cross and I don't think voxl-vision-hub has been moved over yet

[Hector Gutierrez]

@Eric-Katzfey
Hi Eric - the exact sequence I'm following is:

$ git clone https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/
$ cd voxl-vision-hub
$ voxl-docker -i voxl-cross
voxl-cross(4.0)$ ./install_build_deps.sh qrb5165 dev
voxl-cross(4.0)$ ./build.sh qrb5165

I've tried both options qrb5165 and qrb5165-2 and both fail at build.

Thanks, Hector

[Hector Gutierrez]

@tom , can I install and use voxl-cross(2.7) concurrently with V4.0 ? Or do I have to delete my V4.0 installation ?

[tom]

@Hector-Gutierrez You can use them concurrently, just specify which to run like so voxl-docker -i voxl-cross:V2.7

If you don't specify which version to use it'll default to whichever is tagged with latest

[Hector Gutierrez]

@tom - that solved the problem . The solution was to download and build using voxl-cross:V2.7
Thanks for the very prompt response ! regards, Hector
