Demo builds but doesn't record nor encode

[starapple2]

This is exactly a model that I have been trying to achieve building on the tutorial at Samsung: Porting and using LAME MP3 on Android with JNI [(http://developer.samsung.com/galaxy/others/porting-lame-mp3-on-android-with-jni)]

However, I constantly get a failure to make the .so with a message, "clang++.exe: error linker command failed with exit code 1 (use -v to see invocation)
make: *** [obj/local/arm64-v8a/libmpwlame.so] Error 1"

I imported your code and it built with Android Studio on Windows 10 (32 bit) without any errors, installed on my LG G5 running Android 7 and tried a voice recording. If it recorded I don't know where it's stored. I then tried to convert a local sound file the app discovered on the phone to mp3 but it seemed to begin the process, as indicated by the output screen, but it just stayed like that for several minuted until I decided it couldn't be taking that long for such a tiny file.

I'd like to use your makefile process to attempt again to make the .so and wrapper but the structure seems so confusing to me after Android Studio opens and executes all the processes.

Is there any suggestion you can make on how I could examine the portion of your project that matches the Samsung tutorial?

Best.
