numerous "undeclared identifier" errors using MEX

Hello-

I have downloaded smoothpatch_curvature_double.c (from Matlab exchange) and am trying to use MEX for the first time. I am on Windows 7, with a 64bit operating system, but am using Matlab 7.1.0.246 (R14) which is of course pretty old. Perhaps it can't access the full 64-bit system (?)

I entered "mex setup" first and chose LCC compiler

then as suggested in the comments, I used the command:

mex smoothpatch_curvature_double.c -v

A huge number of errors like those below occurred. Can someone please help me? Thanks very much in advance! Greg

Error smoothpatch_curvature_double.c: 25 undeclared identifier `mwSize' Error smoothpatch_curvature_double.c: 25 undeclared identifier `PneigDims' Warning smoothpatch_curvature_double.c: 25 Statement has no effect Error smoothpatch_curvature_double.c: 26 illegal statement termination Error smoothpatch_curvature_double.c: 26 skipping `int'

MATLAB R14 is only a 32 bit executable (but those will generally execute on 64 bit Windows)

MATLAB R14 is not known to work with Windows 7.

Thanks, Walter. As I recall, when my information services people installed my old Matlab on new Windows 7 machine, they found that they had to choose "XP mode" for the display options, and then it worked fine. Still, it would be good to upgrade and make use of the 64-bits. Greg

Try putting this at the top of the smoothpatch_curvature_double.c file:

#ifndef MWSIZE_MAX
#define  mwIndex        int
#define  mwSignedIndex  int
#define  mwSize         int
#endif

James- This did the trick, and I now have a program that is working beautifully. Thanks again!
