[yocto] How do you build 2 versions of the same recipe and a specific version from bitbake cmd line

[Jimi Damon]

Hi,


Do to a fun "feature" of zeromq, the newest libraries are not backward 
compatible and hence I need to install a zeromq-4.1.5 and zeromq-3.2.2 
libraries onto my target to assist with one application using the old 
version and a newer application using the newer one.


How can I do this from the local.conf file AND how can I specify a 
single recipe version to build on the command line ?


I've tried this in my local.conf


CORE_IMAGE_EXTRA_INSTALL += "zeromq_4.1.5 zeromq_3.2.2 "


but I get errors saying :

> WARNING: Host distribution "Ubuntu-16.10" has not been validated with 
> this version of the build system; you may possibly experience 
> unexpected failures. It is recommended that you use a tested distribution.

In addition , how can I specify a specific version of a package from the 
command line with bitbake ?


Here are my layers

% bitbake-layers show-recipes | grep -A 2 zeromq

> zeromq:
>   meta-oe              4.1.5
>   meta-oe              3.2.2


Now this fails


bitbake zeromq-4.1.5

> WARNING: Host distribution "Ubuntu-16.10" has not been validated with 
> this version of the build system; you may possibly experience

or


bitbake zeromq_4.1.5
