Good day, I need to build the native pjsip library(libpjsua2.so) for Android. But I get "undefined refference" errors when building for specific architectures. The build succeeds when I don't target an architecture. I believe it defaults to armeabi. This is my current setup: Android NDK: NDK r13b (october 2016) pjsip Version: 2.8 OS: Ubuntu 14.04 LTS These are the steps I followed (AND IT WORKS): 1. export ANDROID_NDK_ROOT=/home/nate/Documents/pjsip/android-ndk-r13b 2. cd /home/nate/Documents/pjsip/2019.06.10.pjsip.v2.5/ 3. ./configure-android 4. make dep && make clean && make 5. cd /home/nate/Documents/pjsip/2019.06.10.pjsip.v2.5/pjsip-apps/src/swig/ 6. make HOWEVER, when I want to target a specific achitecture with the below steps I get errors: 1. export ANDROID_NDK_ROOT=/home/nate/Documents/pjsip/android-ndk-r13b 2. cd /home/nate/Documents/pjsip/2019.06.10.pjsip.v2.5/ 3. TARGET_ABI=armeabi-v7a ./configure-android --use-ndk-cflags 4. make dep && make clean && make 5. cd /home/nate/Documents/pjsip/2019.06.10.pjsip.v2.5/pjsip-apps/src/swig/ 6. make the below are the errors I get when running step 6: /home/nate/Documents/pjsip/pjproject-2.8/pjsip/lib/libpjsua2-arm-unknown-linux-androideabi.a(endpoint.o)(.text._ZNK2pj8Endpoint13mediaMaxPortsEv+0x0): error:
