After having selected an area to zoom then the
plot disappears. Resizing the plot window may
bring the plot back, but octplot has gone into
an unstable state and is not really responding.
Typing octplot_redraw does not bring back the
plot.
Has anybody seen this problem ?.
I also noticed that when I select an area
to zoom, then the selection window is very
slow to update when I move the mouse. Is
this normal or is it a side effect of the
problem mentioned above.
My system is :
Debian Etch (testing)
Some details from config.log
octplot is configured with:
fltk: version 1.1.6 with OpenGl support
octave: octave (version 2.1.72)
mkoctfile: mkoctfile for Octave 2.1.72

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
This looks like a unique problem. Maybe it is connected with the gcc-4 problem (it's like a scapegoat now -- everything is gcc's fault). To see if this is indeed the probem, try setting GLIBCXX_FORCE_NEW=1 before runnign octave, e.g.
GLIBCXX_FORCE_NEW=1 octave
Tell me if it helps

In my login script to avoid the crash.
However I added
export GL_SWAP_TYPE=COPY,
as you suggested in you README file.
Octplot now works !!
As far as I can understand from
you note GL_SWAP_TYPE=COPY is needed
when there is no HW support for OpenGL.
However kinfocenter shows that I have HW
support on my "Intel Corporation 82845G/GL
[Brookdale-G]/GE Chipset". According to
the configure log (config.log) from octplot
I have :
configure:4325: checking for fltk-config
configure:4343: found /usr/bin/fltk-config
configure:4356: result: /usr/bin/fltk-config
configure:4380: checking for OpenGL support in fltk
configure:4395: result: yes

Shai,
I had already added :
export GLIBCXX_FORCE_NEW=1
In my login script to avoid the crash.
However I added
export GL_SWAP_TYPE=COPY,
as you suggested in you README file.
