Thread Subject: Mex32w error

Hi,

I am running a Simulink model developed by a colleague (Im
in Germany, he is in Spain, so it is difficult to
troubleshoot over email).

A previous version of the model worked fine, he changed a
few entries in an Excel file where the parameters are
stored, now the updated model does not work. This only
applies to my system - his works fine.

The error message I get is:

??? Invalid MEX-file 'C:\Programme\MATLAB71
\work\agrobiogas\gui\agrobiogas_model\reactor.mexw32': Die
angegebene Prozedur wurde nicht gefunden.

.

??? Invalid MEX-file 'C:\Programme\MATLAB71
\work\agrobiogas\gui\agrobiogas_model\reactor2.mexw32': Die
angegebene Prozedur wurde nicht gefunden.

.

??? Error using ==> sim
--> Error while obtaining sizes from MEX S-
function 'reactor' in 'anaerobio_2R/S-Function'. MATLAB
error message:
Invalid MEX-file 'C:\Programme\MATLAB71
\work\agrobiogas\gui\agrobiogas_model\reactor.mexw32': Die
angegebene Prozedur wurde nicht gefunden.

That bit in german is "module is not found".

I have tried many things like using the Simulink debugger
and reusing the old model. But even with the old model I
now get the error - which I did not get before. Very
strange.

Any ideas!!

Thanks
Matt

I used Dependency Walker which told me that two dlls
(dwmapi.dll and efsadu.dll) were not found, so I installed
them and the new error message from DW is:

due to a missing export function in an implicitly dependent
module

This relates to the funcion:

mxCreateDoubleMatrix_700

As the code was compiled on another person's computer
(possibly running a different version of Matlab), could
this then be the problem!

Ideas please...

Thanks

Matt

I get the exact same error message, when I try to load a
mexw32 file with LoadLibrary in VC++. For legacy reasons I
have a 2006a version on my computer, and loading a mexw32
file created with 2006a works fine. Seems to me there is an
issue in 2007b.
