RE: Mkoctfile cygwin

[Keshab Man Shrestha \(Dr\)]

Hi Bill,
        Thanks for the hints.

        I also installed Octave following the procedure posted by John
Eaton ( on Wed Jan 14 13:37:15 2004). I can also compile the
oregonator.cc inside the cygwin shell. Then I run octave and inside
octave I entered "oregonator ([1.2.3].0)". This causes the octave to
close (without any messave - may be it the message is quick for me to
see) and I get back to the cygwin shell.

        May be there a way to capture the error message. I am new to
cygwin and unix. I have been using  the window version of octave.
However, recently I tried got a program written in Matlab which I tried
to run using octave with some necessary modifications. However, I
realized the the program was very slow compared to matlab. I figured out
the slow ness has to do with accessing individual element of a vector
which is necessary in this case. Therefore, I though of writing
dynamically linked function to do this part of the process. This is how
I ended up trying to run mkoctfile. Since I do not like to use matlab, I
have been spending quite a bit of time figuring out the process involved
in writing dynamically linked function in C++.

        Any help on this is highly appreciated.

Keshab

My guess would be that you're getting a segmentation fault when running
your code and that the error goes by too quickly before the window
closes. 
If you can find a way to run a shell and then run octave separately,
then you should be able to find what the error is exactly when octave
drops back to a shell.

I don't run octave in windows with the same installer as you, so I don't
know how to get to the shell, but I'm guessing that there is probably a
batch file that starts it that you should be able to investigate to do
it.
