Count_Binary alt_u8 not found

Thanks. I right clicked on the project name, count_binary, selected Properties, C/C++ General, Paths & Symbols and added a library path to the count_binary_bsp ... HAL/inc. That took care of the errors caused by alt_types.h. However, the error "cannot resolve NULL" is being caused by the stdio.h library. That include is in the count_binary.h file and should NOT have to be in the count_binary.c. When I put it in the .c file the error goes away. It appears that Eclipse or the preprocessor is not even reading the count_binary.h file which is the only include in count_binary.c. Whoever designed these examples didn't have an# include stdio.h (left and right errors don't work in these posts) in the count_binary.c so why do I? So, what path should I put for the stdio.h?
