Help with basic Hal Component

I am trying to develop my own custom Hal components to interface between Linuxcnc and my mill. I wrote a very basic Hal Component in C, but can not get the component to compile. If someone can help debug my file I would greatly appreciate it. Once I can figure out how to get a basic Hal component file to work I should be able to build on it for more complex functions. I have included both the hal component file as well as the error messages I got when trying to compile it. I am running Linuxcnc 2.7.4.

Copy pasting your code compiled ok here.

Are you sure that you have the same name of the component and the file name?

Check if you did:

I thought that I had, but let me check it in the morning. The names were spelled the same, but there might have been a difference it capitalization. I forget that capitalization, or the lack there of, is important on a linux based machine.

It is good knowing that the component code compiled correctly.
