Are you running Octave in the build tree with the run-octave script?
And is your build tree separate from your source tree?
This problem happens after
changeset: 22682:08aa03dfb00e
user: Rik <address@hidden>

summary: Allow switching gnuplot_binary value during a session.
because the gnuplot_binary.m file is generated and so is stored in the
build tree. But the private functions like __gnuplot_has_feature__ are
in the source tree. Since the private directory where
__gnuplot_has_feature__ is located is not a subdirectory of the
directory where gnuplot_binary is located, Octave doesn't find it.
I also noticed another problem due to this changeset. The test executes
gnuplot_binary ("X")
and that now ends up calling __gnuplot_version__ which attempts to
execute the command "X --version". On many systems, "X" is the X11
server. So then I see errors about the X server failing to start
properly and Octave hangs.
It also seems bad that "gnuplot_binary (new_prog)" will now call
gnuplot_binary recursively. It currently works because the persistent
value that stores the program name is set before calling
__gnuplot_version__, but that seems a bit fragile.
For now I've backed out this changeset.
I'm also wondering how important it is to be able to change the gnuplot
binary during a single Octave session. Is this something that comes up
frequently?
