[Octave-bug-tracker] [bug #49767] publish.tst failure when OSMesa excluded from build

[Dan Sebald]

Follow-up Comment #6, bug #49767 (project octave):

This makes sense Mike.  A new test result is too much of a change right now.

Would the "skip" determination need to check for gnuplot in runtime?  I'm not
sure.  I believe there is no build option for leaving out the gnuplot scripts,
so they are always present in a properly installed Octave.  It seems to me it
is simply a case of checking whether gnuplot is installed in the OS in that
case.

There should be a OS script that could simply run gnuplot and check whether
that fails, e.g.,

gnuplot -e "exit"

If there is some way the Make process can issue that OS command and then THAT
make script command indicates fail, that would be the case of no gnuplot.  So
if Make could determine both built without OSMESA and the above system command
fails, then it should skip.

Does that sound doable?  If so, I could add to the patch changes.
