How to use LibTomCrypt with Contiki

I am trying to use LibTomCrypt library with Contiki OS but it's not working at all. I get the error: fatal: Not a valid object name HEAD. I have used the following code for computing hash in my client file.
unsigned char* hashSHA1(const char* input, unsigned long inputSize) {
//Initial
unsigned char* hashResult = (unsigned char*)malloc(sha1_desc.hashsize);
//Initialize a state variable for the hash
hash_state md;
sha1_init(&md);
//Process the text - remember you can call process() multiple times
sha1_process(&md, (const unsigned char*) input, inputSize);
//Finish the hash calculation
sha1_done(&md, hashResult);
// Return the result
return hashResult;
}
and then I call it in send_packet().
I have added the header file
`#include <tomcrypt.h>`
Now in Makefile, I am not sure how shall I add a path. I have checked a few possible ways, for instance, Contiki mote type creation error when trying to use libtomcrypt library (rsa public key generation) and I have added the following lines :
PROJECT_SOURCEFILES += sha1.c
MODULES += ./libtomcrypt-develop
PROJECT_LIBRARIES+= $(CONTIKI)/libtomcrypt-develop/libtomcrypt.a
(here libtomcrypt-develop is the name of the folder containing LibTomCrypt library)
According to my understanding, I guess there is something wrong in Makefile. Can someone please identify the problem in Makefile?
