How to build caffe.so?

@lei9wang See src/jni/CMakeLists.txt, you should link android lib log.

I change STATIC to SHARED, then run ./tools/build_android.sh, the error as following:

95%] Linking CXX shared library ../../lib/libcaffe.so
CMakeFiles/caffe.dir/blob.cpp.o:blob.cpp:function caffe::LogMessage::print(): error: undefined reference to '__android_log_print'

anyone can help give a guide?

I remove the __android_log_print temporarily, then Compiled successfully, thanks

it's okay, refer to src/jni/CMakeLists.txt, I link android lib log in src/caffe/CMakeLists.txt
