Re: [Matlab-emacs-discuss] How to debug MEX files (C code) from Emacs?

[Dong T. <ti...@me...>]

Hi Eric, all,

Thanks for replying.

It is non-trivial to attach the matlab process to gdb.

Matlab provides a command line option -Dgdb to associate the Matlab process
for gdb debugging. Would it be easier to launch "matlab-shell" with -Dgdb
as option? Maybe your or someone else could put lights on this approach?

Thanks,
Dong
