Description (last modified by mderickx)

The first error occurs during

make Theora.pdf which is defined in $THEORA_SOURCE/doc/spec/Makefile. Changing the two occurences of \begin{figure}[Htbp] to \begin{figure}[htbp] in doc/spec/spec.tex solves this issue but now it is stuc at a more serious problem:

Error building libtheora

this seems to be because png_sizeof was removed from lib_png version 1.6.0, see [1] and we ship lib_png 1.6.29.

  • Priority changed from blocker to major

An optional package failing to build should in general not be a blocker, unless maybe if it is a recent regression. I only said that optional packages causing doctest failures (or more general breakage) should be blockers.

comment:5 Changed 5 years ago by mderickx

I have looked a bit into this, and I could not find a place where this package actually enhances the sage library so this would just be a package that is easy to install in sage the distribution. However I don't really see what the reason is to have this package in "sage the distribution" without some easy user accecible way to generate fancy movies out of sage output. So one solution might even be to remove this from the optional packages and make it into an experimental one.

Does either of you agree with this? If so I will ask on sage-devel if people agree with this.

Aditionally the ticket where this package was added #7297 does not provide a good motivation about why it should be added.

Proposal: downgrade to experimental

  • Branch set to public/23732
  • Commit set to 0fe2e6e70a32b9070c463314f00367c107072f35

Here a trivial patch performing the downgrade. It can already be reviewed from a technical point of view. But this ticket should only be given positive review after the consensus on the sage-devel topic I opened for this is that it is indeed ok to downgrade this package to experimental:
