Mex function -Error:Module could not be found-Checked with dependency walker and added the folder to the path but still the same problem

Hi All,

I have compiled the following code http://www.shivakar.com/programming/creating-matlab-mex-function-for-postgresql-database-connectivity/ using visual C++ compiler to create a mex32 file. When I try to run a MEX-file I created, I receive the following error: ??? Invalid MEX-file 'MEX-file name': The specified module could not be found. where "MEX-file name" is the name of my MEX-file. However, I did not receive any errors when compiling the file.

I used dependecywalker to check the dll depedency and it shows the 'libmx.dll and libmex.dll' missing. Thereafter I have added the path 'C:\Program Files\MATLAB\R2011a\bin\win32' where these dlls reside and also tried to add these dlls directly to the folder of the mex function but I am still getting the same error.

please help me how can I attach these dlls to my mex function.

Regards Sumit

libmx.dll and libmex.dll should already been added to the system path in the MATLAB environment. To verify, execute the following command at the MATLAB prompt:

!echo %PATH%

You should find that C:\Program Files\MATLAB\R2011a\bin\win32 is already on the path (preferably the first directory on the path).

I have the same problem too. Have you found the way to solve it?

Make sure that the Visual C++ compiler that you are using is one of the supported compilers for R2011a.
