Hello Team, Greetings of the day! I was trying to generate libpjsua2.so file using following link: https://trac.pjsip.org/repos/wiki/Getting-Started/Android I am getting confused in few steps and because of that I am not getting success. Can you please help me with the following questions: 1. I have properly set ANDROID_NDK_ROOT and JAVA_HOME path. But while performing *Building and running pjsua2 sample application* command, I am getting error like > /home/aanalmehta/Android/Sdk/ndk/18.1.5063045/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/lib/gcc/aarch64-linux-android/4.9.x/../../../../aarch64-linux-android/bin/ld: > cannot find -lpj-aarch64-unknown-linux-android > clang++: error: linker command failed with exit code 1 (use -v to see > invocation) > Makefile:165: recipe for target > 'android/app/src/main/jniLibs/arm64-v8a/libpjsua2.so' failed > make[1]: *** [android/app/src/main/jniLibs/arm64-v8a/libpjsua2.so] Error 1 > make[1]: Leaving directory > '/home/aanalmehta/Documents/Pjsip/pjproject-2.9/pjsip-apps/src/swig/java' > Makefile:27: recipe for target 'all' failed > make: *** [all] Error 1 I am not getting any solution over here. 2. I tried to download latest NDK file from https://developer.android.com/ndk/downloads and now I am getting following error > In file included from > /home/aanalmehta/Android/android_ndk/android-ndk-r20/sources/cxx-stl/llvm-libc++/include/type_traits:406: > /home/aanalmehta/Android/android_ndk/android-ndk-r20/sources/cxx-stl/llvm-libc++/include/cstddef:50:9: > error: no member named 'ptrdiff_t' in the global namespace > using ::ptrdiff_t; >       ~~^ 3. Do I need all four folders - arm64-v8a, armeabi-v7a, x86 and x86_64? If yes then how to generate all four folders? As I am giving TARGET_ABI=arm64-v8a ./configure-android --use-ndk-cflags --with-ssl=[your_openssl_path]/openssl-1.0.2a it's only generating arm64-v8a folder inside jniLibs. 4. If I got success in generating .so file then how to use it in my current project. What things need to be taken care? Your answers will help me a lot. Thank you for your precious time. Thanks and regards, Aanal Mehta
