simulink toolbox portability
显示 更早的评论
I have a toolbox for simulink that used to work fine with version 7.0.1 now I have 7.9.0 and it does not work anymore. On running the model it gives the following message "Invalid MEX-file 'I:\Matlab\ESP\NST_DENS.dll': The specified procedure could not be found." I have the above said file in the folder but it seems I need to develop it again?? How do I go about fixing this.

Did you switch from using 32 bit before to using 64 bit now? If so then the old dll would not work.

When MATLAB reports an Invalid MEX-file it usually means the file was compiled for a different platform (Win32 vs Win64) than the one you are running on. You recompile the file if you have the original source code.
Often for a file mymexfile.dll the source file is mymexfile.c.
To recompile it may be as simple as running the following command in the directory with the source file:
mex mymexfile.c
If the MEX file has additional dependencies your compile command will be more complicated. See the following technical note about MEX

Also, you can determine whether your DLL is 32-bit or 64-bit by using dumpin (http://support.microsoft.com/kb/177429) with the /headers option.
