#101 Pre-Packaged Demo Program Errors
I have successfully installed octplot 0.3.9 using ./configure, make, and make install
When I try to run the demos that come with octplot, I get the errors shown below for each demo. Below that is information about the computer system I am using, including the processor, memory, and operating system.

I see that the /usr/libexec/octave/2.9.8/site/octplot-0.3.9 directory, containing all of octplot's files is no in your path.
did you issue the toggle_octplot command before trying the demos?

I didn't realize that I needed to run toggle_octplot first. I ran that command, and now the demos cause octave to crash:

so, what happens if you just try:

Hmm, well it was worth the try ....
I need deeper debugging. I would be happy if you bear with me:
you need 2 terminals.
in terminal 1:
octave
octplot_enable
octplot_command("noop");
in terminal 2:
ps -u yourusername
find the pid of the octplot process -- call it PID
gdb /usr/libexec/octave/2.9.8/site/octplot-0.3.99/octplot PID
c
in terminal 1:
plot(1:10);
send me the output of gdb from terminal 2

Very strange -- it seems octplot just exited. just to make sure this is a legitimate exit, can you please add the following breakpoint just before entering "c" in gdb:
b octplotapp.cpp:166
b octplotapp.cpp:266
c
and see if it hits the breakpoint?

Hello octplot guys,
My system is a Dell OptiPlex GX260 (2400 MHz)
with an Intel 82845G/GL/GE/PE/GV graphics card. I have
WinXP SP2 with CygWin 1.5.24-2 that includes octave-2.1.73
as well as octave-forge and octave-headers. I'm using
the svn-456 and compiling with gcc-3.3.3-3.
I have gone over to the directory containing the
pre-packaged demonstration scripts in the svn456 of
octplot-0.3.9 to see whether I could reproduce the problem
experienced by Brent Barbee. I do get errors on just two
of the demo scripts: bar_demo.m and layer_demo.m.
Fortunately, they seem to be exactly the same error:
octave:25> bar_demo;

</output>
The output of the variable 'dx' comes from __bar.m at
line 109. There needs to be a semi-colon there to suppress
that output. The real problem is something about the way
that __bar.m calls the function patch.m.
My output from bar_demo.m and layer_demo.m are figures
with single black rectangles in the regions where the scripts
failed on the first patch that they needed to graph. I have
attached two jpegs of the output that I saw.
It seems to me that this may be broken because of
recent changes to patch.m.

Hello guys,
Well. I lied. I did not attach my two jpegs
because I have not been able to convince the
SourceForge site to permit me to do that. I figure
you guys can generate your own output.

Hello Shai,
All of the problems that I could reproduce from this
thread have been addressed. If we could get Brent or someone
else with a Fedora/Octave-2.9.8 system to try the svn, maybe
we could close this thread.
