OK, this did the trick.  Removing all of the old cruft enabled normal operation.  Thanks!

I would like to close these two bug reports.

The file is

usr/local/share/octave/4.3.0+/m/plot/util/ishghandle.m shadows a built-in function

Your rm did not delete it.

I did try to remove with
cd /usr/local/
rm -rf octave*

I still get the same error so there must be a reference somewhere else on the filesystem.

ishghandle.m is a leftover from older versions.

Prior to running "make install" delete the old installation.
I usually do something like


cd /usrlocal
find ./ -name "*octave*" | xargs rm -rf


but perhaps there are better ways.

I also have this warning:
warning: function /usr/local/share/octave/4.3.0+/m/plot/util/ishghandle.m shadows a built-in function


It seems to be the culprit, but I'm not sure how to handle this.

I built a new version today even with a make distclean.

New information is that Octave behaves correctly under ./run-octave

The installed version gives this error. 

I do not remember the last time this worked correctly though.  There is no other information except dozens of lines of those errors.  I tried to track this down but was not sure where ishghandle is defined.

I'm not seeing this on linux Mint.  Those line numbers seem to suggest ishghandle() not returning some correct value.  ishghandle() is the core of all these and is done in graphics.cc while the rest are script files.

Is there any more error message info other than those numbers?  Can you recall the last time you downloaded and compiled the development version for which this worked?

I have built Octave from sources and am getting error messages related to the graphics subsystem.

Just entering graphics_toolkit("fltk") (or gnuplot for that matter) give a number of lines such as this:
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    ishandle at line 41 column 10
    ishghandle at line 41 column 10
    isfigure at line 37 column 10
    graphics_toolkit at line 63 column 5

In fact entering "close all" from the command prompt gives the same behavior.
