The compiler driver will pass the option to the linker and the latter will load multi-thread (MT) run-time libraries."<BR /><BR />As a background, I'm compiling a static fortran lib and linking that into a c++ dll compiled with visual studio, /MD, and libguide40.dll. What is the benefit to compiling the c++ code with /MT vs /MD?<BR /><BR />Thank you,<BR />Jon<BR /> Thu, 12 Jun 2008 19:59:55 GMT knowdat 2008-06-12T19:59:55Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/compile-code-with-MT-option/m-p/874229#M8771 <BR />In the user's guide for mkl 10 on chapter5 page 7, it says, "To use threaded Intel MKL, it is highly recommended to compile your code with the /MT option.

I don't think that comment in the user's guide distinguishes between /MD and /MT; rather, it is meant to warn against mixing non-thread-safe libraries of past Microsoft 32-bit compilers with threaded code.
