"module could not be found" using MATLAB mex with Fortran and intel mkl

Question

I am trying to execute a MATLAB mex function written in Fortran that uses Intel MKL with the following setup (per http://www.mathworks.com/support/compilers/R2015b/):

1. MATLAB 2015b, Win64
2. Visual Studio Professional 2013
3. Intel Visual Fortran Composer XE 2013 SP1
4. Rogue Wave IMSL* Fortran Numerical Libraries 7.0.1

So far everything compiles successfully, e.g.,

mex -v Fsolution.f90 COMPFLAGS="/Qopenmp $COMPFLAGS" ...
-I"C:\Program Files (x86)\Intel\Composer XE 2013 SP1\redist\intel64\mkl" ...
-I"C:\Program Files (x86)\VNI\imsl\fnl701\Intel64\include\dll"

yields

del Fsolution.exp Fsolution.lib Fsolution.mexw64.manifest Fsolution.ilk
MEX completed successfully.

However, Fsolution.mexw64 fails to execute with the following error:

Invalid MEX-file '...\Fsolution.mexw64': The specified module could not be found.

Dependency walker shows that

MKL_INTEL_THREAD.DLL "Error opening file. The system cannot find the file specified (2)."

As an alternative I compiled with

mex -v Fsolution.f90 COMPFLAGS="/Qopenmp $COMPFLAGS" ...
-L"C:\Program Files (x86)\Intel\Composer XE 2013 SP1\mkl\lib\intel64" -lmkl_intel_thread ...
-I"C:\Program Files (x86)\VNI\imsl\fnl701\Intel64\include\dll"

but received the same errors in both MATLAB and dependency walker. Other mex functions that do not rely on MKL_INTEL_THREAD.DLL execute without error.

Answer 1

I have the same problem when executing a MATLAB mex function written in C that uses Intel MKL. Dependency walker shows the same problem. I just copy the file (find in the computer, usually in C:\) to the folder where the C file exists. Then it works.

Hope this will help.

Answer 2

This problem was the result of a change to the name of the dynamic library. In IMSL Fortran Library Version 6 the dynamic library was "link_fnl_shared.h". In version 7, it is named "link_fnl_shared_imsl.h".

See IMSL Fortran 7.1 Getting Started Guide - Windows.
