Error using mex: Unable to complete successfully

Hi,
I have downloaded a program written in C, and wish to run it in Matlab.
To do this is use the mex to compile it into Matlab.
This has worked for me for the entire (academic) year. However, I tried to use it today and I got the error;
'Error using mex
Unable to complete successfully.'
along with a list of lots of errors in the code.
I have no idea what's going on. It worked fine before, but suddenly does not. I have not changed the code in any way, I even re-downloaded it in case the file had been corrupted (the code is written by Liverpool University, so is reputable source).
Please could somebody help with this problem; this is my Final Year Project at University, and the deadline is soon.
Thank you in advance.

It would seem to help if you would actually read the errors and heed them.
There's a missing header file called "stdafx.h" that undoubtedly has the
declarations that being missing cause most if not all of the remaining
errors.
Either locate this file from wherever you got the other or fix the path
statements/include environment variable to allow the file to be found by
the compiler; whatever is the appropriate action depending on whether
you have the file at hand or not...

OK, but there's no need to be so rude about it; this is way beyond my expertise and I didn't know what the errors meant.
I am now no longer getting the error lcc preprocessor error: Miguel_2D_unwrapper.cpp:9 Could not find include file "stdafx.h"...
just the other syntax errors.
Any ideas why?
Thank you

statement of a fact the compiler found.
As far as the rest, it's impossible to tell w/o a revised set of errors
given w/ the previously missing file available because there's no reason
to think the same errors are existant in it's present as would be w/o it.

Are you certain that they're the same exact errors? Debugging compiler
issues like this can be somewhat of an iterative process; fix problem,
recompile, find new problem, repeat.
In addition to showing the errors, please show a small segment of the code
referred to in the error message, say two commands before and two commands
after. Sometimes a compiler will report a problem on line 17, say, that's
actually caused by a problem (missing semicolons, in particular) on line 16
or 15.

Hi,
Thanks for your help so far. I think the problem is the compiler. When I have done the mex setup, I have been using the compiler which is included with Matlab (Lcc-win32 C 2.4.). But I just downloaded Microsoft Software Development Kit (SDK) 7.1 and used the compiler provided in that, and it seems to work fine now.
Perhaps there is an issue/bug with the Matlab compiler? (This might make sense as I had to reinstall Matlab recently, and it has been since then that I have been having these problems).
Thanks
Katherine

It is an "issue" but it is not a "bug"
MS is notorious for using extensions and other proprietary features in
their compilers and other software products that do not follow
established Standards.
Undoubtedly the code you have downloaded was developed on and for and
uses some of these specific MS extensions.
That other compilers don't implement all of these features doesn't make
them buggy, only incompatible. For the inexperienced these may
superficially look to be the same thing but there's a big difference in
the conceputalization.
Your choices are to continue to use the MS-specific tools or convert the
code to a more platform/OS-independent form. If there is no need for
the code except on a supported OS, then you may as well stick w/ using
the MS compilers (just recognizing the need for the specific toolset).

Katherine,
What likely happened is that when you reinstalled Matlab it defaulted back to the provided compiler, which won't know about stdafx.h, which is a standard pre-compiled header file used only by visual studio I believe. Re-running mexsetup to use the Microsoft compiler fixed the problem.

Ahh ... I missed a clue here. Your code is written in C++, yes? I remember
you mentioning that the errors were being reported in a .cpp file.
LCC is a _C_ compiler.
http://en.wikipedia.org/wiki/LCC_%28compiler%29
Using a C compiler to compile C++ code _may_ work but probably will not.

Oh, yeah, I saw the extension but didn't think to comment on that
aspect, either, Steven, as well as the MS-specific portion of the code
being dependent on VS.
