Have you generally followed the pattern shown in the GitHub example ?

GitHub - SketchUp/ruby-c-extension-examples: Ruby C extension examples

I build my DLL and ruby loads it when I start Sketchup, then I click the button my ruby added to the toolbar and in turn it calls my ruby script which then call my DLL.

1. You should be building a .so file, that defines a main function prefixed "Init_" with the remainder of the name the exact same as the .so file’s filename. This is a requirement so that Ruby’s global #require can load the file. (See the example above, or the book on writing Ruby C extensions.)

2. You need to be linking to the correct lib for running inside “live” SketchUp application.
