Similiar strange error in visual c 6 when linking

SDL Development
1

I’ve also faced a similiar problem.

At first I got :-
msvcrt.lib error please use /NODEFAULTLIB:library

When I added /nodefaultlib at the linker option, I could not use the
string.h library.Whenever there is a string.h library was called it has
error although I the string library in was included.

Could anyone pointed out that which library must be omitted besides
msvcrt.lib in order to avoid the confict ?

Does this is a normal behaviour setup in Visual C++ ?

FYI:
I’ve gone thru a how to setup in the net and follows the all of the steps.
