I am compiling project in Visual Studio 10, compiled executable runs fine on win 7 but it doesnt works on win xp because of missing msvcrt100.dll. I tried to use "/NOTDEFAULTLIB" but it also removes some other external libs that i use. Is there way to not link against latest Microsoft runtime library ?
To not link against the DLL you must link against the runtime statically.
To do this, go to C/C++ Properties -> Code Generation and under Runtime Library select Multi-threaded (/MT) or Multi-threaded Debug (/MTd) from the drop-down. Note, once you're using a static runtime library all of your other library code you link against must also be built with the same setting. And you will also likely have to add additional libraries to the Linker -> Input under Additional Dependencies.
