Go to "Project->Build options->Linker->Link libraries", click "Add", type GL and press "OK".

You might want to try the OpenGL template provided with Code::Blocks. This normally works and you can copy/paste the settings.
You might also install the OpenGL DevPack (use the DevPack plugin for download) to make sure you have the right libraries and other "stuff" installed.

Open Code::Blocks, select "File" -> "New Project...". Scroll down in the templates and seelect the "OpenGL Application". Click on "Create". Right-Click on the project and veryfiy the settings made in the project options and build options. Especially make sure the path's is setup (added) in a way the compiler can find the OpenGL libs and headers.

I didn't notice that you are now on slackware. Your first post was about an ".exe " so I thought this in a Win32 application. The OpenGL template is only available for Windows. Sorry. But: I guess it should be easy possible to adopt the template for Linux. You might want to download the source code of Code::Blocks, extract the OpenGL template (it's under templates\win32) and give it a try.

I don't have access to a Linux box otherwise I would provide you with it.

...wait a minute: There should also be the GLFW template available und Linux. This is based on OpenGL (as far as I know) so it might be a good starting point as well. You should only have to remove the "glfw" library...?!

Please, somebody correct me, if I'm wrong.
