trying to compile my first libraries

[GiuseppeDini]

I'm new to c++ and I'm trying to understand how libraries work with c+
+.
I have a project (opencv, but this question is not opencv specific)
with a folder for each library, and in each folder two folders
"include" with headers and "code" with some headers and .cpp files.
Furthermore there are two folders outside "bin" with .dll files and
"lib" with .lib files.

What I want to do is to produce .lib and .dll files by myself using my
IDE (codeblock, but not necessary), so that I can modify the source
code if I want.

If I choose a shared library or a dynamic library project and take all
the files in a source folder in my project, compile and link them I
get, in both case, two files: cxcore100.dll (980 Kb) and cxcore.a
(607Kb).
The original files were cxcore100.dll (989 Kb) and cxcore.lib (80Kb).

Why the second file is much bigger, do I be wrong somewere?

It looks like you have a windows question rather than a C++ one, try a
windows programming group.

The way libraries are compiled, linked and referred is so different
between windows and linux?
I think the situation if I did the same things on a different OS would
be the same.

Unix/Linux dose not have .dll or .lib files. They have static (.a) and
dynamic (.so) libraries.

How they are built is both platform and tool specific.

This group is for C++ language questions. Questions about tools are
best directed at platform or tool specific groups, you will get better
help there.
