When you build on the Visual Studio command line, you must build the program in two steps. 

First, run cl /c /EHsc MyLib.cpp to compile the code and create an object file that's named MyLib.obj. 
(The cl command invokes the compiler, Cl.exe, and the /c option specifies compile without linking. For more information, see /c (Compile Without Linking).) 
Second, run lib MathFuncsLib.obj to link the code and create the static library MathFuncsLib.lib. 
(The lib command invokes the Library Manager, Lib.exe. For more information, see LIB Reference.)
