[Octave-bug-tracker] [bug #51344] [octave forge] (video) warning: comparison between signed and unsigned integer expressions

[Nicholas Jankowski]

Follow-up Comment #1, bug #51344 (project octave):

evaluating current state with v5.1.0 on Windows.  Granted 5.1.0 currently has
the latest version. I tried to 'overinstall' the video package and got an
install error.  (neglected to copy the error before closing Octave).  I then
uninstalled video and attempted to reinstall producing the following install
failure:


octave:7> pkg install -forge video
