Description

I consistently get the following error when trying to generate a PDF for https://en.wikipedia.org/wiki/Book:Compiler_construction

Generation of the document file has failed.

Status: Rendering process died with non zero code: 1

For reference, here's the link used to trigger the rendering:
https://en.wikipedia.org/w/index.php?title=Special:Book&bookcmd=rendering&return_to=Book%3ACompiler+construction&collection_id=56195b07e09a2dcf87cc6c890edf37c01e6f1921&writer=rdf2latex&is_cached=1

Of course the ideal would be for this to succeed, but if it's a problem with the content itself it would be good to have more specific messaging, so that the content could be edited to resolve it.

I don't currently see any option for rendering in any other format, so I can't tell of the problem is PDF-specific or more general.

Admittedly my version of OCG is quite out of date at this point, but:

As already announced in Tech News, OfflineContentGenerator (OCG) will not be used anymore after October 1st, 2017 on Wikimedia sites. OCG will be replaced by Electron. You can read more on mediawiki.org.

Declining this task as "The Wikimedia Foundation's book rendering service has been withdrawn", plus OCG has been dead for years and superseded by Proton and Electron-PDFs on Wikimedia servers.
If there is still an issue with currently available functionality on Wikimedia servers, then please file a new ticket with updated information and steps to reproduce. Thanks!
