How can I see the command-line options that the mex() command passes to the C compiler?

I would like to see what command-line the mex() command passes to the C compiler. How can I do this?

(p.s. I have a more specific purpose; I'm sharing a semiportable .h file with another project, and I need to #ifdef out some lines when the mex() compiler is used.)

Try the debugging:

mex -v ...

If the C-file needs to consider a compilation from a mex command, you can explicitly create a flag:

mex -DCalledFromMex ...

And in the C-code:

#ifdef CalledFromMex

The symbol defined by the MEX command by default is:

#ifdef MATLAB_MEX_FILE
 // code here
#endif
