attribute error during check_overlinking in conda-build-3.3.0

A long working recipe now fails with the recent conda-build release.

forgot to mention that I'm using conda-forge as highest priority channel.

[mingwandroid]

Ah ok, this is my fault. This codepath was probably never exercised. Working on a fix now.

[mingwandroid]

OK, with that PR on macOS and with conda set to error on overlinking via this in ~/.condarc:

conda_build:
  error_overlinking: true

.. I now get:

[marscher]

Looks good. Thank you!

[msarahan]

Fixed in #2652, new release coming soon.

[Colelyman]

I am experiencing the same problem. Is there an ETA for the new release with this fix?

[msarahan]

@Colelyman later today. Sorry for the inconvenience.

[msarahan]

@Colelyman conda-build 3.4.0 is available now.
