RE: Debugging octave mex files

[Trigui, Hafedh (OTT)]

I wrote the mexFunction and other C++ functions in visual studio 2005 and also 
used the VS2005 compiler and linker. The use of octave is restricted to pass 
variables and read outputs of mex files. 
Everything run perfectly with octave 3.2.4 (sorry for the typo in my previous 
email).

Since now I am moving in the direction of complicating my C++ code, I started 
to think about debugging and ideally using VS2005 (very nice GUI, line by line 
debug, variables watch...).

Do you or anyone else has a good idea on how to debug mex files?

Thanks 
Hafedh

What does this question have to do with Octave? You produced a mex file with 
Matlab's mex binary, which is not something Octave can use at all. You would 
need to recompile your code with mkoctfile --mex if you want to produce a mex 
file for Octave. I am also not sure about using that compiler. How are you 
making Octave a part of this?

By the way, where did you get that version of Octave? Did you mean 3.4.3? Did 
you compile it yourself?

oct files, but they use a different API than mex files (for backwards 
compatibility, Octave also provides a C++ API to mex files). They can be 
debugged like any other

Am I the intended recipient? I'm not sure. I hope I am. If not, I can erase 
your email, if you wish.
