Description Daniel Moerner 2020-07-27 20:16:23 UTC

If you open certain pdfs (e.g., https://www.jstor.org/stable/42705831) with mupdf 1.17.0-2.fc32, it shows a blank screen and shows the following error in the terminal:

warning: jbig2dec error: incompatible jbig2dec header (0.17) and library (0.18) versions (segment -1)
error: cannot allocate jbig2 context
warning: Ignoring error during interpretation

Rebuilding mupdf fixes this problem. This also breaks packages that build against mupdf, like zathura-pdf-mupdf.

Comment 1 Michael J Gruber 2020-07-27 20:50:42 UTC

Oh well. The issues is that jbig2dec is not abi stable. I do try to keep jbig2dec abi stable nonetheless, but recently jbig2dec apparantly started to be be smart ass and check the version of the (unversioned) library against the version of the headers which a programm was compiled against. I'm still lacking a good solution and am open to concrete suggestions. (I've got enough non-concrete ones already.)

As a stop-gap, I will require the exact jbig2dec version in mupdf and rebuild against jbig2dec 0.18. Probably zathura-pdf-mupdf should do the same then.
