title: Linking header files in codeblocks
body: <p>So I've written code in OpenCV which contains 2 header files using Code::Blocks. When I compile the files, there are no errors except two "undefined reference..." errors which occur because I have used functions that I have declared in the header files. I assumed that code blocks automatically linked the header files? I have used the "#include.." to include the header files at the top of the programs so not sure what the problem could be. Anyone have any idea? Thanks.</p>
