programming is howing error

Anshik Kulshreshtha

i am working on a project for the automatic power reading using gsm
but getting some errors:
please check the program and guide me

    Exactly what guiding do you feel you need?

    codec.c(2): warning C318: can't open file 'lcd.h'
codec.c(3): warning C318: can't open file 'rtc.h'
codec.c(5): warning C318: can't open file 'bcd2ascii.h'
codec.c(6): warning C318: can't open file 'serial.h'

    Do you have such files?

    You are including them with <> like:

    #include <lcd.h>
#include<string.h>
#include<bcd2ascii.h>
#include<serial.h>


    Which would imply that they are files available in the standard include paths - but they are not part of the C standard so why do you expect the compiler to find them?

    If you did copy code from an existing project that did use these files - why haven't you then also copied these files?

    And remember that it isn't enough to have header files. You also need a library, object files or C/C++ files that contains the actual implementations of the functions.

    In the end, this is standard C questions - how to make use of additional code modules written by someone else and get the compiler to find the header files, build all relevant source files and then link the program together with the extra modules.
