Dear All,

I am using getch() to read the character from keypad in my code.

But when I Run the code, I am getting below error.


Error [499] ; 0. undefined symbol:
_getch(trial code.obj)

I am using PIC16F877 with hi-tech c compiler.

Can you suggest me why this error occur.
 

Have you included the header, 'h' file where the getch() function prototype is defined?
Have you linked to the library where the getch() function is coded?
