I am trying to compile a C file in mex, and get the below error, which seems to be originating from a header file. I am using SDK compiler. I have little experience with C, so please let me know what more information you would need to get, as I am sure this question does not have enough detail.
Error Message:

You forgot to attach owl.h with the paperclip icon so someone can inspect it and find the syntax error in it.

Thanks. The system wouldn't let me attach it, so I just copy/pasted it.
