What is contained in lib?
-
What's the difference between import liberary and static program liberary, they seems to have the same suffix(.lib)? Can somebody provide me the explicit demonstration of lib file. BTW, i have learnt PE format already.
When you compile a file called, say, "A.cpp", you normally get an output file called "A.obj". Essentially a
.libfile is a library that contains multiple.objfiles. Historically there was a separate command for creating them. If you've studied the PE file then you're already know most of what you after. See here[^].Steve

And an import library contains the signatures of the exported functions and the name of the DLL file that contains the actual implementation.

thanks! why lib is smaller than dll? if lib is the combination of all objects, and dll also a combination of all objects(some have been allocated though), dll should be equal of smaller in size than lib. And are you saying import liberay and static program liberary are exactly the same?

lib doesn't contain any "logic" inside. It's just a dummy. It contains information about the exported symbols from the dll. How will it have the same size of the dll then? But if it's a static library, yes, it will have brains and the size will be big. Unlike a dll, this static libraries get "fixed up" to the executables. But I guess you aren't concerned about the latter.

That's not necessarily true. Import libraries just contain, essentially, function names and the name of the containing DLL, so it’s true in that case. However, the “other” sort of lib file contains machine code and data.

It need not be. If it's an import library it will be quite small.

Did you really read my message till the end?
