How to fix these three RadASM compile errors?

[bilbo]

I modify GetLastError as below, but don't works.

@4 means the total number of bytes required by function arguments (google for __stdcall calling convention). Now, GetLastError has no args at all. So, if you open kernel32.lib with an hex editor (I suggest you HxD) and look for GetLastError, you will find _imp__GetLastError@0 and not _imp__GetLasterror@4

Is there easy way can work it out for all Unresolved external symbols below?

have a look at this link

Sorry, I'm newbie on this

I like the approach you are following. I learned a lot of things using exactly the same approach than yours. By the way, how have you solved the assembly errors from defines such as
ms_exc = CPPEH_RECORD ptr -18h
in _tolower.asm?
