Re: Octave GUI MinGW first light & need help.

David,

Ok, I could track this down but it's probably easier for you. My tarball is
here: http://www.cs.mcgill.ca/~mtakan1/octave-gui-beta.tar.gz (about 300KB.)

Basically, it goes into octave_main() and returns 1. What I need to know is
why? Can you tell me what the failure is?

Things you should know:

1) This is a Windows app. So it doesn't have an stdout and stderr. Apologies
for the added debugging difficulties.

2) Therefore, I stick the return value of octave_main() and the argc, argv
into some global variables. When the gui comes up, I print those global
variables in the output tab. So you can see exactly what the parameters to
octave_main() are and that it returns 1.

3) Trolltech decided, in its infinite wisdom, that they weren't going to
play game with msys. Therefore, it is not possible to do make if msys is in
the path. Therefore, when you want to *build*, you have to open a clean
cmd.exe and add *only* c:\octave\MinGW\bin to its path, nothing else. Then
you type make. This is summarized in compileenv.bat.

Warning: Don't try to use qmake. It'll fubar everything.

4) On the other hand, when you run octave-gui.exe presumably you'll need the
environment to be set up as with octave.exe. So I made an octave-gui.bat by
copying your octave.bat and changing the executable. Since it will munge
your environment, I usually start it from the windows explorer (file
manager), not from the prompt.

Let me know,
