How to build fips compliant sqlcipher to call FIPS_mode_set(1)

I built libcrypto.so.1.0.0 with fips compliant as described here

I tried to include libcrypto.so.1.0.0 (by creating symbolic link for the file libcrypto.so in android libs folder) and tried to call FIPS_mode_set(1) where I find error - as undefined reference - FIPS_mode_set(1).

Here are steps where in detail I have followed so :

In class,net_sqlcipher_database_SQLiteDatabase.cpp (in jni folder) in the sqlcipher code, I included the following headers files :

#include <openssl/crypto.h>
#include <openssl/fips.h>
#include <openssl/ssl.h>

Then I added the following method in the above class

/*fips mode enable native native void fips_set_mode(int i) */
static void fips_set_mode(JNIEnv* env,jobject object,jint i){

FIPS_mode_set(1); // it should call FIPS_mode_set(1) from fips.c class

}

and I have added above method declaration in the following table

//methods
static JNINativeMethod sMethods[] =
{
    /* name, signature, funcPtr */
    {"dbopen", "(Ljava/lang/String;I)V", (void *)dbopen},
    {"fips_set_mode","(I)V",(void *)fips_set_mode},
    {"dbclose", "()V", (void *)dbclose},
    {"enableSqlTracing", "(Ljava/lang/String;)V", (void *)enableSqlTracing},
    {"enableSqlProfiling", "(Ljava/lang/String;)V", (void *)enableSqlProfiling},
    {"native_execSQL", "(Ljava/lang/String;)V", (void *)native_execSQL},
    {"lastInsertRow", "()J", (void *)lastInsertRow},
    {"lastChangeCount", "()I", (void *)lastChangeCount},
    {"native_setLocale", "(Ljava/lang/String;I)V", (void *)native_setLocale},
    {"native_getDbLookaside", "()I", (void *)native_getDbLookaside},
    {"releaseMemory", "()I", (void *)native_releaseMemory},
    {"setICURoot", "(Ljava/lang/String;)V", (void *)setICURoot},
    {"native_rawExecSQL", "(Ljava/lang/String;)V", (void *)native_rawExecSQL},
    {"native_status", "(IZ)I", (void *)native_status},
};

Then in SQLiteDatabase.java (in the src folder), I have added following native method declaration :
```
//setting
static public native void fips_set_mode(int i);
```

Finally, I called above method in loadLibs method of SQLiteDatabase.java

//loadlibs

public static void loadLibs (Context context, File workingDir)
    {
        System.loadLibrary("stlport_shared");
        System.loadLibrary("sqlcipher_android");
        System.loadLibrary("database_sqlcipher");   
        fips_set_mode(1);

}

Then I did make to compile the sqlcipher code.. But I am getting following error

jni/net_sqlcipher_database_SQLiteDatabase.cpp:252: undefined reference to `FIPS_mode_set'.

Please any suggestion's in this regard would be appreciated

Solution

Have you verified that the fips.h header file exists? The Android.mk file within the root jni folder for android-database-sqlcipher project includes the external/openssl/include path during the build.
