i replace caffe with myself caffe, then ./tools/build_android.sh There is link error like this: canning dependencies of target caffe [ 57%] Linking CXX shared library ../../lib/libcaffe.so [ 57%]

if compile static library libcaffe-jni, it is okay. @solrex , could you give guide about this issue?

solrex commented 6 years ago

@lei9wang Sorry, you cannot do that. The caffe source code in this project is modified, a lot. You can only add some self-defined layers, and fix the compiling errors yourself.
