Dennis, how did you download the sketch? The ubitx_cat.cpp doesn¡¯t look like c code. It¡¯s more like part of GitHub website code. Could happen if one use right click on the file for downloading instead using the green button firbclonenor zip download.
Which git repository were you using? I don¡¯t see *.cpp files in Ashars repository, only *.ino Files.
