Thread Subject: Linking C++ and Matlab using VS2003

I'm trying to run the engdemo.c program.
I'm using MATLAB 2008a and Microsoft C++ Visual Studio 2003 on a
Windows XP machine.

At first I was getting the following error:
error C2065: 'Engine' : undeclared identifier

So i added the following line to my cpp file:
#include "C:/Program Files/MATLAB/R2008a/extern/include/engine.h"

But then I would start getting a couple of the following errors:
error LNK2019: unresolved external symbol _engClose referenced in function
_main

So I added the following to my code:
#pragma comment (lib,"C:/Program Files/MATLAB/R2008a/extern/lib/win32/
microsoft/libeng.lib")
#pragma comment (lib,"C:/Program Files/MATLAB/R2008a/extern/lib/win32/
microsoft/libmx.lib")
#pragma comment (lib,"C:/Program Files/MATLAB/R2008a/extern/lib/win32/
microsoft/libut.lib")

This made the program link and compile. However, upon running the
program, it would close with the following error:
Unable to Locate Component
This application has failed to start because libeng.dll was not found. Re-
installing the application may fix the problem.

So I copied libeng.dll from C:/Program Files/MATLAB/R2008a/bin/win32 to
my project directory. It then asked me for another dll, which I also copied.
This went on a couple of times until I got tired and copied over all the dlls in
the win32 directory to my project directory. The program now opens and
immediately crashes. A window pops up with the following message:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: c:\Documents and...
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

The output on my project window says:
Severe:
MATLAB:I18n:MissingICUData - ICU Data not found.
The program '[2760] c:\Documents and
Settings\Administrator\Desktop\simple\PumaClient.exe: Native' has exited
with code 2 (0x2).


I have read the "Compiling and Linking MATLAB? Engine Programs" section
of the help. but I'm obviously confused and would really appreciate if you
could walk me on this one...

Thank you very very much!

How are you compiling your program? Are you using the mex
command from the MATLAB command line, or are you trying to
do the compile from within the Visual Studio environment?
I usually do the compile using the mex command at the
MATLAB prompt, but this usually means I have to manually
copy any dll files from the C++ or Fortran compiler
directories and then specify them in the mex command to
get the link to work. I haven't tried the other way, as
you seem to be doing.

I'm trying to compile it directly from VS2003. I solved my problem
downgrading from the latest version of Matlab to 6.5 (which I had lying
around). It now works perfectly only with the linking of the libraries + dll
files.


Could this be a bug in Matlab R2008a?
