Running make pdfdocs on a Ubuntu 16.04 system fails with
Makefile:58: recipe for target 'media.pdf' failed
make[2]: *** [media.pdf] Error 1
Documentation/Makefile.sphinx:79: recipe for target 'pdfdocs' failed
make[1]: *** [pdfdocs] Error 2
Makefile:1442: recipe for target 'pdfdocs' failed
make: *** [pdfdocs] Error 2
It's not clear from the voluminous (>5MB) output from make pdfdocs
exactly which stage is failing, and there are some pdf files produced
in output/latex.
This is with sphinx, rst2pdf, and texlive installed from the Ubuntu
repositories.

Hmm, so it does. It comes down to this:
! LaTeX Error: \DUrole undefined.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.195 \renewcommand*{\DUrole}
[2]{ #2 }
Where the offending command is in Documentation/media/index.rst. Mauro,
got an idea for what's going on there?

Sphinx is really a poor solution when it comes to PDF output. In this
specific case, this is meant to fix a problem with cross-references.
What happens is that Sphinx 1.4.6 (and later?) define reference names without
being properly escaped. So, for some references, it causes the PDF output
to crash. That happens at one of the DVB header files, if I remember well.
This commit restores the sphinx 1.2.x behavior:
commit e61a39baf74dddb6cd236147bd19b55c10188d78
Author: Mauro Carvalho Chehab <[email protected]>
Date: Sun Aug 21 15:14:57 2016 -0300
[media] index.rst: Fix LaTeX error in interactive mode on Sphinx 1.4.x
The Sphinx 1.4.x definition for \DUrole is:
\providecommand*{\DUrole}[2]{%
\ifcsname DUrole#1\endcsname%
\csname DUrole#1\endcsname{#2}%
\else% backwards compatibility: try \docutilsrole#1{#2}
\ifcsname docutilsrole#1\endcsname%
\csname docutilsrole#1\endcsname{#2}%
\else%
#2%
\fi%
\fi%
}
This is broken when it is used inside a \begin{alltt} block.
So, replace it by just "#2", as this won't cause troubles, and
it is one of the fallback methods for it.
Signed-off-by: Mauro Carvalho Chehab <[email protected]>
At the time I tested, it worked fine, but maybe it is redefining the
\DUrole too late.
Maybe we could move it to LaTeX preamble instead. Please check if this
untested patch fixes the issue.

Yes, this seems to be the case. The patch below should fix it.
[PATCH] docs-rst: fix PDF build errors
PDF build on Kernel 4.9-rc? returns an error. This is
because we're re-defining a command too late. Move
such redefinition to LaTeX preamble.
Tested by building the documentation on interactive mode:
make PDFLATEX=xelatex -C Documentation/output/./latex

After applying the patch I'm seeing a similar error message
[...]
Running Sphinx v1.3.1
[...]
! LaTeX Error: \DUrole undefined.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.79 ^^I\renewcommand*{\DUrole}
[2]{ #2 }
but in a different place
Makefile:58: recipe for target 'development-process.pdf' failed
make[2]: *** [development-process.pdf] Error 1
Documentation/Makefile.sphinx:79: recipe for target 'pdfdocs' failed
It was failing with the media.pdf target before.
And there was a development-process.pdf file created; it doesn't have
the table of contents but from a quick look the actual text looks
reasonable.

Ah! you're running version 1.3.1...
We should likely add some logic at conf.py to only enable this on
Sphinx 1.4.x...

Could you please apply just the hook that remove the index.rst
raw LaTeX command and see if it will build fine in interactive
mode?

I'm not a python programmer, but, after playing with conf.py for a while,
I guess that the following patch should do the right thing applying the
LaTeX fix only for Sphinx 1.4.x.
---
[PATCH v2] docs-rst: fix PDF build errors
PDF build on Kernel 4.9-rc? returns an error. This is
because we're re-defining a command too late. Move
such redefinition to LaTeX preamble.
Tested by building the documentation on interactive mode:
make PDFLATEX=xelatex -C Documentation/output/./latex
Fixes: e61a39baf74d ("[media] index.rst: Fix LaTeX error in interactive mode on Sphinx 1.4.x")

Well, xelatex has a few modes of operation:
-interaction=STRING set interaction mode (STRING=batchmode/nonstopmode/
scrollmode/errorstopmode)
on batchmode, it doesn't complain about any errors, but doesn't produce any
error. On the default mode (errorstopmode), it will stop on the first error.

Ok, but this one is on another place ;)
If it is the same issue that happened on Sphinx 1.4.x, it is due to
the lack of some column specification on a .. tabularcolumn markup.
I have already a series fixing all errors with PDF on 1.4.x.
Just submitted. Please check it it makes ok on Sphinx 1.3.x.
Cheers,
Mauro

FYI: as far as I know those "!LaTeX Error" messages cause TeX
to end with an error code which stops the make build.
Since we are not in an interactive mode, xelatex continues
after each "!LaTeX Error" messages and builds the pdf to
its end (even if the content might be broken).. and then,
it ends with exit status !=0.
In those cases (make build stops), we have to study the log file.
BTW: I prefer Jani's solution, using the "batchmode" [1] and
if a pdf build fails, I have to read the *.log file in the
latex output folder searching for those "!LaTeX Error".
