unable to undefined reference to 'pj

Trying to build pjSIP from sources for Android, using following guide - https://trac.pjsip.org/repos/wiki/Getting-Started/Android

Checkout sources of pjsip (2.5)

export ANDROID_NDK_ROOT=/home/dev/android/android-ndk-r9b

export TARGET_ABI=armeabi

export APP_PLATFORM=android-13

./configure-android --use-ndk-cflags --disable-video --disable-l16-codec --disable-gsm-codec --disable-g722-codec --disable-g7221-codec --disable-ssl --disable-ilbc-codec --disable-tls

configuration is completed successfully.

make dep && make clean && make

And I got following error - >

../src/pj/guid_android.c:43: error: undefined reference to 'pj_jni_jvm'
../src/pj/guid_android.c:117: error: undefined reference to 'pj_jni_jvm'

The command invoked by linked which leads to this error

Code of guid_androind.c

#include <pj/guid.h>
#include <pj/log.h>
#include <pj/string.h>

#include <jni.h>

extern JavaVM *pj_jni_jvm;

static pj_bool_t attach_jvm(JNIEnv **jni_env)
{
    if ((*pj_jni_jvm)->GetEnv(pj_jni_jvm, (void **)jni_env,
                               JNI_VERSION_1_4) < 0)
    {
        if ((*pj_jni_jvm)->AttachCurrentThread(pj_jni_jvm, jni_env, NULL) < 0)
        {
            jni_env = NULL;
            return PJ_FALSE;
        }
        return PJ_TRUE;
    }

    return PJ_FALSE;
}

#define detach_jvm(attached) 
    if (attached) 
        (*pj_jni_jvm)->DetachCurrentThread(pj_jni_jvm);

Struggling with this error for whole day, any clue is highly appreciated. Meanwhile I'm able to build version 2.3 without any errors, but not 2.5

I believe you missed a step. https://trac.pjsip.org/repos/wiki/Getting-Started/Android#BuildPreparation

Set your config_site.h to the following:

/* Activate Android specific settings in the 'config_site_sample.h' */
#define PJ_CONFIG_ANDROID 1
#include <pj/config_site_sample.h>
