Intel® Math Kernel Library 2018 Update 2 Developer Guide
The IA-32 architecture implementation of Intel MKL supports the Compaq Visual Fortran* (CVF) calling convention by providing the stdcall interface.
Although the Intel MKL does not provide the CVF interface in its Intel® 64 architecture implementation, you can use the Intel® Visual Fortran Compiler to compile your Intel® 64 architecture application that calls Intel MKL and uses the CVF calling convention. To do this:
Provide the following compiler options to enable compatibility with the CVF calling convention:
/Gm or
/iface:cvf
Additionally provide the following options to enable calling Intel MKL from your application:
/iface:nomixed_str_len_arg
