First, the good news. The message you're getting is a warning, not an error. That means it shouldn't prevent the binary from being built.

Second, the better news. The warning message is telling you that you don't need to have the semicolon at the end of the #endif
That's because lines that start with a # are preprocessor macros that are textually replaced before the actual C compiler gets to see them.
