Debugging Matlab Mex Files with Eclipse+CDT [message #184538]

Hi all,
For those who are interested, i made this little Flash tutorial on how
to use eclipse to debug mex-files under linux.

http://info-te.ch/~geli/mexdebug/mexdebug.html

This should also work on Windows if you install gnumex
(http://gnumex.sourceforge.net/) in combination with the MinGW compiler.
But when useing windows, do not debug matlab from start, instead start
matlab, execute your mex file (in order for matlab to load the
corresponding dll !!!)
-------
Tip: make shure that your mexfile "return;"s if for instance
"nlhs==0"... so you can execute (and thus load) the mex file without
harming matlab: This is usefull if you want to debug Segmentation
Violations etc...
-------
then attach with eclipse to your MATLAB process, set your breakpoints
etc... resume matlab and call your mexfile again with the appropriate
parameters

Best regards
Geli

Thanks for the tutorial, it was a great help for me as I am new to
Eclipse. I am trying to debug mex files on Windows using MinGW/gnumex.
I can build the mex file using make, but I am not sure how to get
Eclipse and Matlab to talk to each other when, as you state, you need to
launch MATLAB and execute the mex DLL independently of Eclipse.

Thanks in advance.

Hello Geli,

I have found your posting concerning the eclipse / matlab debugging topic and tried your link:

http://info-te.ch/~geli/mexdebug/mexdebug.html

towards the short tutorial.
I do not have a password or login...

I would be happy if you could send me that tutorial in order to speed up my intended integration of eclipse and matlab as a combined development environment.

Best regards,

Daniel
