issues in creating c linux library

Hi I am creating an openssl wrapper c library to be use with JNI. My c source file name is rsa.c and JNI header file name is OpensslRSA.h which is contain in both JAVA_HOME/include and JAVA_HOME/include/linux directories. I am using below syntax to create this library .
gcc -shared -fpic -o librsa.so -I/usr/local/jdk1.7.0_45/include -I/usr/local/jdk1.7.0_45/include/linux rsa.c

This c program uses below header files

#include <jni.h>
#include <stdio.h>
#include <OpensslRSA.h>
#include <openssl/pem.h>
#include <openssl/ssl.h>
#include <openssl/rsa.h>
#include <openssl/evp.h>
#include <openssl/bio.h>
#include <openssl/err.h>

but when I use this from java program as below
java -Djava.library.path=/home/agarwal/test/c_tests/opensslrsalib OpensslRSA
then it give below error
java: symbol lookup error: /home/agarwal/test/c_tests/opensslrsalib/librsa.so: undefined symbol: BIO_new_mem_buf
Can any body let me know what should I do for this as all the header files used exist in /usr/include as per there use in c source

BIO_new_mem_buf is in the openssl library. You have to link your library with -lcrypto (lower case L) or with what pkg-config --libs openssl gives you.
