Steps already taken:

Installed VS 2005 Express
Installed Win 7 SDK
Installed VS 2005 x86 Runtimes SP1 + MFC Security Update
Set the environment variable MSsdk to the SDK path.
Installed Borland 5.5 Compilers
Installed MinGW and Gnumex.

All the compilers will compile a C++ s function successfully. However, when trying to reference those files using an s function block I get an 'error obtaining sizes from Mex. Specified module could not be found'.

Has anyone successfully compiled a C++ s function on the set up described.

I must use 32 bit to be compatible with the work of my colleagues.

The 'Specified module could not be found' error usually means that you are missing one or more DLL dependencies. Please see if this solution helps you debug the issue: How do I profile my EXE or DLL file with Dependency Walker?

PS: The S-function MEX-file is really a DLL with a MEX-specific extension, so you can treat it like a DLL in debugging.

Hello, thanks for your prompt reply.

I typed the following at the command window:

!C:\Work\depends22_x64\depends.exe sfun_cppcount_cpp.cpp

Returning "No DOS or PE signature found. This file is not a valid 32-bit or 64-bit Windows module."

Then I tried

!C:\Work\depends22_x64\depends.exe sfun_cppcount_cpp.mexw32

Returning:

"Error: At least one required implicit or forwarded dependency was not found. Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module. Error: Modules with different CPU types were found. Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module."

I also have error opening file:
