lpc17xx_rtc.o error

If you are not getting any errors, that means the compilation is ok.
(to "Translate" press "Ctrl+F7" _Shortcut keys_)

Now,
"CLKPWR_ConfigPPWR" is a function called from your "lpc17xx_rtc.c" file, but the linker is unable to find the function (in the "lpc17xx_rtc.c" file).

i m sure that the function is defined in some other file. may be "lpc17xx_clkpwr.c" file!!

so how do you tell(inform) the linker that the function code exists in some other file?
