Invalid MEX-file The specified procedure could not be found : Calling a CUDA MEX function

superbot · April 24, 2012, 8:50pm

I want to use some mex function in MATLAB ( http://patternsonascreen.net/cuSVM.html) that is written with CUDA language for executing on Nvidia GPUs.

I start with building .mexw64 version of it using the Visual Studio, But I got the invalid mex file error when I tried to call it in MATLAB:

??? Invalid MEX-file 'I:\cusvm_vs2005.mexw64': The specified procedure could not

be found.

I already used the dependency walker. Initially the “IESHIMS.DLL” and “MSVCR80.DLL” are missing. I put the first in system32 and the second in current matlab folder.

The Dependency Walker still get error:

Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.

Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

The DLL-tree has a red "nvcuda.dll" block and a red "ieframe.dll" block in its sub-tree.

I currently use VS2005, Matlab 2010b, Window 7 (64 bit), cuda toolkit 3.2.

The original cuSVM code is implemented on window xp (32 bit) and VS2005, So It has .mexw32 version in its package.

I uploaded two files of the project:

-mex function and its MATLAB test code

-visual studio project that builds the .mexw64 file.
