[EDIT: 20110711 16:37 CDT - reformat - WDR]

I am trying to compile a legacy code originally written in FORTRAN and converted to C using 'f2c.exe' into an S-function for use in SIMULINK. Previously people have been able to compile the code (on older versions of MATLAB), and now I'm trying to recompile to code. I get a linking error:

C:\PROGRA~1\MATLAB\R2009A\BIN\MEX.PL: Error: Link of 'myProgram.mexw32' failed.

The verbose output from the compiler follows:

mex myProgram.c haspms32.obj hasp32b.obj -v

Sorry, forgot to ask if anyone knows why it's failing or has any possible solutions to try. Thanks a ton for the help!

That Link failed message isn't very helpful, is it?

I think I would be tempted to download the appropriate Microsoft SDK for your release, in hopes that a more useful error message was generated.

You can find the list of compilers for 2009a here

John: If you look at the list of compilers on Walter's link above, MSVC 2010 is not a supported compiler for R2009a. You can either upgrade to R2011a or get a supported version of MSVC.
