Linking Error

[archna . mittal]

Hi,
  I am a new to the makefile world. I am trying to write a makefile
which consists of two files,but at the compilation time it is giving me
linking error. I do have a feeling that it is makefile error.

/******Makefile***********/
LOCAL_OBJS=DecryptApi.o TESTDRV.o

TESTDRV: $(LOCAL_OBJS)
         arm-linux-gcc -o TESTDRV TESTDRV.o DecryptApi.o -L. -lsddklib

TESTDRV.o:TESTDRV.C
        arm-linux-gcc -g -c TESTDRV.C

DecryptApi.o:DecryptApi.C
        arm-linux-gcc -g -c DecryptApi.C
/**********End of Makefile*****************/



After compling I recieve the error:

/***********************************************************/
arm-linux-gcc -o TESTDRV TESTDRV.o DecryptApi.o -L. -lsddklib
TESTDRV.o: In function `main':

collect2: ld returned 1 exit status
make: *** [TESTDRV] Error 1
/**********************************************************/


While all these functions (NMSec_init(void),NMSec_deinit(void)) are
defined in
DecryptApi.C.

Any pointers are highly appreciated.

Thanks in Advance,
