pdf docs fail to build (prefix) sage-9999 (7.3.beta4)

[strogdon]

Initially with sphinx-1.4.1-r3 I get failures similar to https://github.com/cschwan/sage-on-gentoo/issues/418

pdfTeX warning: pdflatex (file ./graph_plot-19.pdf): PDF inclusion: invalid oth
er resource which is no dict (key 'XObject', type <null>); ignored.

!pdfTeX error: pdflatex (file ./graph_plot-19.pdf): PDF inclusion: invalid font

 ==> Fatal error occurred, no output PDF file produced!

and after upgrading to sphinx to 1.4.2 I now have

LaTeX Warning: Hyper reference `sage/rings/asymptotic/growth_group::doc' on pag

1.4.2 and 1.4.3 are no good to build pdf doc. I will put 1.4.4 when it is out, which should be much better. Now "invalid font...." we should be able to get something out of that.

[kiwifb]

Is it all with en?

[strogdon]

yes

[kiwifb]

Hum.... Upstream may have an idea but first I should prepare a live ebuild so we are sure things are still broken after their big latex re-org (which breaks things in 1.4.2 - what you saw - and is still present in 1.4.3).

[kiwifb]

1.4.4 is out! So I will ship that.

[kiwifb]

OK 1.4.4 is in the overlay and I will test it on my side too.

[strogdon]

OK, rebuilt sage with sphinx-1.4.1-r3 and now no errors. Perhaps a parallel build thingy? So I'm wondering if https://github.com/cschwan/sage-on-gentoo/issues/418 was really due to the fix for that issue.

[kiwifb]

Parallel build is a possibility. Does it happen with vanilla or you don't know?

[strogdon]

vanilla builds just fine, but vanilla is on a machine with 4 cores. the prefix machine has 12 cores.

[strogdon]

Builds and installs with sphinx-1.4.4. Clearly the issue is not sphinx-related.

[kiwifb]

Lets keep it open until we have more clues.

[kiwifb]

Is this over?

[strogdon]

I had to manually upgrade to sphinx-1.4.4-r1. Useflags had changed and I had not updated mine, so I hadn't built the pdf docs since https://github.com/cschwan/sage-on-gentoo/issues/427#issuecomment-226070995 - something I had overlooked. Here the pdf docs do build and install with 1.4.4-r1 and L10N=en. So perhaps the phantom had moved on.

[kiwifb]

And we are moving to sphinx-1.5.3 in the next snapshot, all the legwork upstream should pay off. And 1.4.1 is gone from the overlay. Closing.
