Re: [Audacity-devel] Error building (with python3 as /usr/bin/python)

[Campbell B. <ide...@gm...>]

Thanks, I tested building and managed to get it working.

A new build is uploaded to https://scan.coverity.com (but no new
issues found :))

I did run into another problem, so its still not building
out-of-the-box though I managed to workaround it, but better post that
separately.
