RE: Debugging octave mex files

[Trigui, Hafedh (OTT)]

I did not use mex or any other command at octave prompt. I solely relied on 
compile and build solution from the GUI of VC++. Then, I manually rename the 
dll file to a mex file.
In octave prompt, I only define the parameters of the mex function and call the 
function.
This time was fine since the function is not doing more than printf and 
returning an integer as an output.
I am worried of the next step when I will have hundreds or thousands of C++ 
code and a debug could be necessary.

The main question is: how did you compile your MEX file?
I'm gonna assume you used the "mex" command at octave prompt. If yes, this 
means you didn't compile the MEX file with VC++, but with MinGW, which is the 
compiler that was used to create the octave release you're using. This also 
means you can't debug it using VC++. You need to use MinGW gdb for that.
OTOH if you manage to use VC++ to compile and link your MEX file against the 
octave libraries (theoretically this is possible as the MEX interface is 
C-only), then normally you should be able to debug with VC++, but only the code 
that's in your MEX file. However, I would not recommend such combination of 
compilers, as you'll end up mixing C runtime DLL's, leading to various problems 
at runtime.
