[Octave-bug-tracker] [bug #55916] pdfTeX warnings in build: found PDF version <1.7>, but at most version <1.5> allowed

[Mike Miller]

Follow-up Comment #5, bug #55916 (project octave):

I have ghostscript 9.26. I've also now tried building the pdf doc images with
gl2ps and with gnuplot (forced with 'env DISPLAY= make all').

With gl2ps 1.4.0:


$ pdfinfo doc/interpreter/splinefit6.pdf 
Title:          gl2ps_renderer figure
Author:         Octave
Creator:        GL2PS 1.4.0, (C) 1999-2017 C. Geuzaine

With gnuplot 5.2.6:


$ pdfinfo doc/interpreter/splinefit6.pdf

You can do a verbose build with 'make all V=1' and see if /usr/bin/texi show
up in the build log.

The error or warning messages that this bug is about, about inclusion of these
PDF images, can only occur in the texi2pdf build command for producing
octave.pdf. If you're not getting octave.pdf, then that's probably related to
this bug.

Octave crashing in bug #55268 is about creating these plot image files. Once
the plot images exist, Octave isn't run anymore.

You could try copying the images from the 5.1.0 official release tarball into
your build tree, and see if texi2pdf builds octave.pdf successfully.
