That codeblock thing I have no idea about but LOOK at the makefile I posted.

The problem is you guys have no clue how the header files work or are
compiled into code, or how one creates shared code via object files, no
do you likely know what an object file is.

And Codeblock makes you even more stupid. You don't need an IDE, your
operating system, that is if you are using a unix variant, is a big
giant IDE.

A header file is generally definitions which create symbols that the
compiler can identify and put aside room for in do. Then the headers
usually have also a shared library (so) or a dynamic linked library, or
in simple cases just an object file, that had to be findable by the
compile that allows it to fill in the definitions that are defined in
the header file.

That is the big #include

Most professional coding involves making OBJECT and shared library
files, because those reusable objects are where the money is AT ... to
sell API's and programmable objects for projects that others create
using your libraries.

In order to link the libraries you have to tell the compiler to go find
them. There are a lot of tools to help this along, like make and
make.deps and autoconf

Ditch the codeblocks thing and use EMACS or GVIM. Actually learn GVIM
and learn the vi editor. You are going to use it for the rest of your
life, so take the time to learn it now.

http://www.unix-manuals.com/tutorials/vi/vi-in-10-1.html

The fundemental insight of vi usage is that the methods of using vi is
included in everything else, like grep, ed, sed, perl, awk, python,
ruby, and all the c variants...not to mention korn and bash (and oracles
stupid sqlplus crap).
