I am trying to compile a UDF. I put the .c file and udf.h file in the same directory as the .cas file. there is no other .h file created by myself. When I clikc "build", it did create the directory and copy a few files in that directory, but when click "load" it gave me an error message say "Error: open_udf_library: The system cannot find the file specified."

Is there anyone can tell me why it happened and how to solve the problem?

Thanks a lot.
