Latest trunk fails to build on my environment. Does anyone know how to resolve this?

+Mike,

https://gerrit.chromium.org/gerrit/#/c/38269/ looks relevant.

make sure your tree is up to date and fully synced. partials syncs
are never supported.

if, after doing that, `cros_setup_toolchains --help` errors out:
- chromite/third_party/pyelftools/ should exist
- chromite/__init__.py adds pyelftools to the search path
- `which cros_setup_toolchains` points to
~/trunk/chromite/bin/cros_setup_toolchains
- chromite/bin/cros_setup_toolchains is a symlink to ../scripts/wrapper.py

#from the correct address

Thanks,

I'm syncing to the tip with the simple "repo sync", but with minilayout. Is it unsupported now?

NO

YES

YES

Gah, my minilayout checkout seems to be old.

I found

> From the root of the checkout, run chromite/bin/loman --upgrade-minilayout .

in minilayout.xml and doing that -> repo sync again resolved the import issue.

Sorry to bother you, and thanks for the response.

FWIW, I saw exactly the same "issue". I followed kinaba@'s instruction (chromite/bin/loman --upgrade-minilayout) and it worked.
