RE: Debugging octave mex files

[Trigui, Hafedh (OTT)]

I downloaded octave from http://www.gnu.org/software/octave/download.html more 
than a year ago. 
I never touched the source code of octave. I am just a user of octave.
Thanks
Hafedh

If your version of Octave was built with VS2005, then what you want to do may 
be possible.

Can you tells us where you obtained (downloaded) Octave?
