FYI, on Debian/Ubuntu/Mint you need to install the package

By "Sphinx never included the actual package" I really mean "Sphinx 
actually included the actual package for a few releases".

By "Sphinx no longer included it" I really mean "Sphinx no longer added 
\usepackage{iftex} by default". Sphinx never included the actual package.

Re: [sage-devel] building pdf docs fails

[John H Palmieri]

'iftex' is required directly because of line 311 in src/doc/common/conf.py:

\usepackage{iftex}

This was added in https://trac.sagemath.org/ticket/22252, to compensate for 
the fact that Sphinx no longer included it by default. The 'iftex' package 
is part of TeXLive; I don't know about other TeX distributions.

A clean build of SageMath...tried this, no change.

Yes, installing the package solved this problem. (So apperently it is
needed..)

Thanks everyone,

Re: [sage-devel] building pdf docs fails

[Volker Braun]

I don't have iftex.sty installed (Fedora 25), so its not required directly. 
Your tex installation might (erroneously) have it as a transitive 
dependency, though. I'd try with a clean build first. Otherwise install the 
iftex package:


$ tlmgr search --file iftex.sty
iftex:
texmf-dist/tex/generic/iftex/iftex.sty

A scan on a sphinx 1.5.3 install says that iftex is not used by sphinx.
I’d say you are somehow still on sphinx 1.4.4 or something stranger.

Well it looks like in 1.4.4 they shipped iftex but then in 
https://github.com/sphinx-doc/sphinx/commit/ead753eaad7e0f73f106c4bda918f916b6d3638c
they removed it again. Because they stopped using it.
We could check whether its use has been re-introduced somewhere else after 
that, I guess.

sphinx 1.4.3 had this problem as an issue, see 
https://github.com/sphinx-doc/sphinx/issues/2639

closed as "fixed" by 1.4.4. Not sure what happened then.

We moved to sphinx from 1.4.4 to 1.5.3 but I must say I don’t think anything
fails here. I have used sphinx 1.5.3 to build pdf documentation for sage 7.6
in sage-on-gentoo, so there may be something more to it. May be you are missing
a texlive package?
