Building plainbox-provider-snappy fails with compile errors

[Jeff Lane ]

I'm trying to build a snap for the server cert provider. I've attached my snapcraft.yaml. When I run 'snapcraft stage', the staging fails while trying to build plainbox-provider-snappy. The following are the console messages encountered:

'plainbox-provider-snappy-resource' has prerequisites that need to be staged: plainbox-provider-snappy

And there the build fails and stops.

Try 'snapcraft update' first, then try rebuilding. Otherwise, it looks like you are missing 'gcc-multilib' in your build-packages somewhere. That should get pulled in by plainbox-provider-snappy though, so I think running snapcraft update should work.

Yep, that cleared it up... that may be worth including in the doc I
was following that Chris has been working on.
