Why do I receive error "unresolved external symbol _vprintf" when building SLRT model on MATLAB R2017a with Visual Studio 2017?

Why do I receive an error when building SLRT model on MATLAB R2017a with Visual Studio 2017? I am trying to build a modified version of the "slrttestmdl" where I use matrix multiplication to multiply two matrices and display them. The error does not occur when I use element wise multiplication, but does occur when using matrix multiplication. The specific error messages I get during the build process are:

libcblas.a(cblas_xerbla.o) : error LNK2019: unresolved external symbol _vprintf referenced in function _cblas_xerbla
libcblas.a(cblas_errprn.o) : error LNK2001: unresolved external symbol _vprintf
libatlas.a(ATL_xerbla.o) : error LNK2001: unresolved external symbol _vprintf

This issue has been fixed in MATLAB R2017b.

The underlying issue was related to updates from Microsoft to the Visual Studio compilers.

For more details, refer to the following link,

https://docs.microsoft.com/en-us/cpp/overview/what-s-new-for-visual-cpp-in-visual-studio?view=vs-2017

And note the following statement:

"Versioning: The value of the built-in preprocessor macro _MSC_VER is now being monotonically updated at every Visual C++ toolset update."
