The compiler (actually the linker) is telling you that it can't find the

char *pcCityIdToCountryName(ADMIN_DB_DATA *pstHEader, unit uiCityID)

code anywhere. Is this function in another module? If so you will have to link against that module.
Code:
cc myfile.c -o myfile -L<some shared library>
or
cc myfile.c somemodule.o -o myfile

The -L syntax requires you to remove the "lib" from in front of the shared library name:
Code:
libcountry.so

becomes:
-L country

The .so or .sl is not needed.

RESOURCE_INT_VALUE(9)					   BSD Kernel Developer's Manual				     RESOURCE_INT_VALUE(9)

NAME

     resource_int_value, resource_long_value, resource_string_value -- get a value from the hints mechanism

SYNOPSIS

     #include <sys/param.h>
     #include <sys/bus.h>

     int
     resource_int_value(const char *name, int unit, const char *resname, int *result);

     int
     resource_long_value(const char *name, int unit, const char *resname, long *result);

     int
     resource_string_value(const char *name, int unit, const char *resname, const char **result);

DESCRIPTION

     These functions fetch a value from the ``hints'' mechanism.

     The functions take the following arguments:

     name     The name of the device to get the resource value from.

     unit     The unit number of the device.  -1 is special and is used for wildcard entries.

     resname  The resource name.

     result   A pointer to memory in which to store the resource value.

RETURN VALUES

     If successful, the functions return 0.  Otherwise, a non-zero error code is returned.

ERRORS

     The functions will fail if:

     [ENOENT]		The resource could not be found.

     [EFTYPE]		Inappropriate resource type.
