error: implicit declaration of function 'create_proc_read_entry' [-Werror=implicit-function-declaration]

Question

I\'m trying to compile a kernel module on kernel 3.13 and I get this error:

error: implicit declaration of function \'create_proc_read_entry\' [-Werror=impli         


        

Answer 1

The error is because you are not including explicitly the header that declares the function and the compiler is 'including' implicitily for you and this throws a warning. The flag '-Werror' is making the compiler treats the warning as an error. Try adding: #include

Also: create_proc_read_entry is a deprecated function.
