[Dev-C++] add to lib

[Wobien <wo...@pl...>]

Hello,
I made some functions and classes I want to reuse in other projects.

I can add the directory with the header files to the include directories and
that works fine.
I also have some .cpp files. It works if I add their object files to the new
project, but then I have to add all the object files one by one to each new
project.

It does not work if I add the directory with the object files to the library
directories.
Probably I need to make files with extention .a or .lib, but how do I do
that?

How can I make a real new library directory?
