Re: building dynamic runtime library through command line.

Is their a simple way to build dynamic runtime library from command

Wait, there are several things you seem to be mixing up:
1. a dynamic runtime, as opposed to a static(ally linked) runtime
This is controlled via the documented switches to the compiler.
2. exporting symbols from a dynamic library vs importing them from one
Typically, if you want to use the same header for static and dynamic
libraries and for exporting and importing, the __declspec(dllexport) is
typically hidden behind a macro. This is then either empty (static linking)
dllexport (building DLL) or dllimport (linking DLL).
3. building a static library vs building a dynamic library
This is basically determined by the linker arguments.
Just for your info, you can watch the commandline that is given to the
compiler by the IDE using some switches in the project settings. Further,
the wizard-generated dynamic and static library projects already do
everything that is necessary, otherwise there are hundreds of existing
projects out there which you can look at.
Lastly, you can also control which symbols get exported from a DLL using a
linker file (.DEF), but that isn't than comfortable.
