Static libraries, dynamic libraries, DLLs, entry p

问题:

I recently had to program C++ under Windows for an University project, and I'm pretty confused about static and dynamic libraries system, what the compiler needs, what the linker needs, how to build a library ... is there any good document about this out there? I'm pretty confused about the *nix library system as well (so, dylibs, the ar tool, how to compile them ...), can you point a review document about the current library techniques on the various architectures?

Note: due to my poor knowledge this message could contain wrong concepts, feel free to edit it.

Thank you

Feel free to add more reference, I will add them to the summary.

References

Since most of you posted *nix or Windows specific references I will summarize here the best ones, I will mark as accepted answer the Wikipedia one, because is a good start point (and has references inside too) to get introduced to this stuff.

Program Library Howto (Unix)

Dynamic-Link Libraries (from MSDN) (Windows)

DLL Information (StackOverflow) (Windows)

Programming in C (Unix)

An Overview of Compiling and Linking (Windows)

Start with Wikipedia - plenty of information there, and lots of links to other useful resources.

P.S. But perhaps it would be better to just ask a specific question about the problem you're currently having. Learning how to solve it may go a long way to teaching you the general concepts.

You can find some background information from this article here. It gives you the basic background. I'm trying to locate something with diagrams. This should be a good place to get started.

The fundamental differences between a static library and a DLL is that with the static library the code is compiled into your final executable whereas a dynamic link library involves linking in a "stub" library (into your application) which contains mappings to functions in a separate file (.dll).

Here's an MSDN entry on creating a static Win32 Library which might also help you. ..another link to MSDN for creating a Dynamic Link Library..

Just found this site which covers definitions of basically all the aspect you've quoted.

There is always MSDN for windows related stuff: Head page for dlls -> http://msdn.microsoft.com/en-us/library/ms682589

For Unix my favorite reference manual: Programming in C, UNIX System Calls and Subroutines using C -> http://www.cs.cf.ac.uk/Dave/C/
