How to make .so shared library use your project ?

[tingfengainiaini]

I am a newbie to android NDK.
Just editing the last line of Android.mk file to "include $(BUILD_SHARED_LIBRARY)" failed the ndk-build.
When make armabi/libjpeg-turbo.so, it gives out undefined reference error, and stopped build.

Do you have an example to generate a shared library by you github project ?
My ndk-build version is r10e. And I can succeed to build static library without error.

Someone knows why ?
