How to get protobufs and zeromq included in Yocto image

stephen_eng — Wed, 25 Mar 2020 18:47:13 GMT

I want to use zeromq and google protobuf for my application. From what I can tell, it looks like the 4.14.78_1.0.0 sumo Yocto build should have a version of zeromq included as part of meta-oe, but I can’t seem to find it anywhere in the image. (No library, no files with zeromq or zmq in the name.) I’m wondering if the default build somehow removed it, or if I need to do something else to ensure that it’s included in the image.

For protobufs, it looks like it’s not there at all… I tried to use devtool to create a ‘protobuf’ recipe, but it fails to build.

Is there another way of adding protobufs to my project?

I’m just going for the fastest path forward. If there’s already a layer that exists for one or both of these components, or a recipe, or something… I would appreciate that.

Thanks,

Hello Stephen,

Protobus and Zeromq aren´t part of yocto for i.MX you can migrate:

protobuf « recipes-devtools - meta-virtualization - Layer enabling hypervisor, virtualization tool stack, and cloud supp… http://git.yoctoproject.org/cgit/cgit.cgi/meta-virtualization/tree/recipes-devtools/protobuf/protobuf_3.0.0.bb?h=morty

Just to check that I understand you.

I would have to add the devtools recipe from the meta-virtualization layer to my image, and make sure those 3 things build?

Is there a spot for zeromq as well? (I plan to use it with Python, if that helps narrow what I need to incorporate.)

Hi, There is no Spot for zeromq you have to change all the register to support it.

It looks like I have zeromq support via Python. (python-pyzmq package is available) I was able to add it to my image, and verify that it connects to my host machine.
