Greetings, I made a static library and various tests programs, obj C and Xcode. Now I am writing a command line tool that uses that library. All running smoothly for a while but now when I attempt to add one of the .h files I cannot select it. It is dimmed. I have added most of them but this one just evades me. I thought that perhaps I didn't "add" the file when I created the library so deleted both it and its corresponging source file and "added" them again. Same result. Any suggestions greatly appreciated.
