llvm dev - May 2017 - [cfe-dev] www-scripts Sphinx doc builder broken and needs intervention.

Thanks Tanya,

Unfortunately it seems like `clang-tools-extra` has started failing again,
with the similar error message "make: *** No rule to make target
`docs-clang-tools-html'.  Stop."

I'm not sure if this is an error on your end or within clang-tools-extra.
I'll investigate more tomorrow.

/Eric

Yes, thank you Tanja. The Polly docs also do not yet seem up-to-date:

http://polly.llvm.org/docs/

despite a recent push to the docs and waiting at least an hour in case
the builds only take place hourly. Or are these only nightly builds?

Best,
Tobias

@Tobias The poly docs build step is still failing, but due to a bug in the
particular version of Sphinx used by the www-scripts builder.
This seems like something best worked around inside poly.

The builds take place hourly and their output is reported on the
www-scripts at lists.llvm.org mailing list.
