ntwin32.mak file not found when using Simulink Coder

Hi, I am using Matlab/Simulink with the Simulink Coder and Vector Canoe AddOn. When building the model I get the following error:

"C:\PROGRA~1\MATLAB\R2015a\rtw\c\tools\vctools.mak(18) : fatal error U1052: file 'ntwin32.mak' not found"

There exists such file in:

"C:\Program Files\Microsoft SDKs\Windows\v7.1\Include\NtWin32.Mak"

Is it possible that the file is not visible to Matlab? Is the case important?

Best Regards,

Clement

Have you used

mex -setup

and if so are you configured to use the Windows 7.1 SDK?

Hi Walter, Yes of course I have used max -setup and it seems to be successful:

MEX configured to use 'Microsoft Windows SDK 7.1 (C)' for C language compilation
.
Warning: The MATLAB C and Fortran API has changed to support MATLAB
         variables with more than 2^32-1 elements. In the near future
         you will be required to update your code to utilize the
         new API. You can find more information about this at:

To choose a different language, execute one from the following:
 mex -setup C++
 mex -setup FORTRAN

It is unlikely that you are encountering difficulties due to the difference in case of the filenames.

"Actually it depends of the software that accesses the FS.

If it uses WIN32 API (which 99.9% of the software does) it will be case-insensitive whatever you do. All built-in software in Windows (like Explorer, command prompt, Internet Explorer and etc.) and all consumer software out there uses WIN32 and is always case-insensitive.

NFS Service, Java and some others are POSIX and they will obey the 'obcaseinsensitive' registry setting."
