How can I download (or compile) the libraries “stdlib.lib” and “stdlib.a”? (To use them for assembly)-Collection of common programming errors

I have the following code:

include stdlib.a
includelib stdlib.lib

But on assembling, it gives me an error: “cannot open file : stdlib.a“

I haven’t any file called “stdlib.lib” or “stdlib.a”.

I’ve been searching for those files, but I can’t find them. The only file I can find is “stdlib.h”(look Ramhound’s answer), but WinAsm doesn’t recognise it on compiling.

Is there any way to transform the “stdlib.h” to “stdlib.lib” or “stdlib.a”, or to use in assembly? ( From Ramhound’s answer : * “stdlib.h” is a header, not a library. It can’t be converted to “stdlib.lib” or “stdlib.a” *).

Thanks!!!

EDIT 1 In Ramhound’s answer, he explains that stdlib.h is a “header”, not a library. Could someone help me with the stdlib.lib and stdlib.a ?

I’ve been looking for those files, but I can’t find them. I would appreciate some help with those libraries. (Why every one have them but I can’t find where to download them?
