[Dev-C++] Adding my own Lib files to Project

[Napoleon A. <nah...@so...>]

Hello,
How do I go about adding my own library files that to a project I'm =
working on. I have some files which I think are general enough that I =
put them in C:\***\lib. In order to add these files to a project I have =
the appropriate include statements. and added the path to the library to =
Project\Project Options\Files.Directories. I get the following Linker =
error:

C/CppLab/Winnie/main.cpp:21: undefined reference to =
`Win::ClassMaker::ClassMaker(char const *, HINSTANCE__ *)'
C/CppLab/Winnie/main.cpp:23: undefined reference to =
`Win::Maker::Maker(char const *, HINSTANCE__ *)'
C/CppLab/Winnie/main.cpp:25: undefined reference to =
`Win::Maker::Create(Win::Controller &, char const *)'

I also added the path to Tools\Compiler Options\Directories which also =
gives me the same error message. When I copy all the files into the same =
directory It compiles without errors. What am I doing wrong ?

Napoleon.
