Solution:

This Solution is specific to the GDB debugger on Solaris. For other configurations, see the Debugging section of Tech Note 1605, MEX-files Guide:
http://www.mathworks.com/support/tech-notes/1600/1605.html

In R12.1 to debug MEX-files (and S-functions) using gcc and gdb, you need to compile it using the following code:

mex -g -f gccopts.sh mexfilename.c.

1. Start MATLAB with

matlab -Dgdb

2. At the gdb prompt type:

run -nojvm

3. At the MATLAB prompt type

dbmex on

4. Type the mexfilename.

5. At the gdb prompt type

shared mexfilename.mexsol

6. Type:

break mexFunction

7. Type

continue

You should then end up inside of the mexFunction

This was done using 2.95.2 gcc and 4.16 gdb.
