Porting caffe to android platform

• Up-to-date caffe (d91572d)
• CPU only
• No support for hdf5

git clone --recursive https://github.com/sh1r0/caffe-android-lib.git
cd caffe-android-lib
# build image
docker build -t caffe-android-lib .
# run a container for building your own caffe-android-lib, e.g.,
docker run --rm --name caffe-android-builder \
    -e ANDROID_ABI=x86_64 \
    -e N_JOBS=2 \
    -v $(pwd)/android_lib/x86_64:/caffe-android-lib/android_lib \
    caffe-android-lib ./build.sh

Tested with Android NDK r11c and cmake 3.5.2 on Ubuntu 14.04

git clone --recursive https://github.com/sh1r0/caffe-android-lib.git
cd caffe-android-lib
export ANDROID_ABI=x86_64
export NDK_ROOT=/path/to/ndk
./build.sh

OpenBLAS is the only supported BLAS choice now, and the supported ABIs are the following:

• armeabi
• armeabi-v7a
• arm64-v8a (default)
• x86
• x86_64

Any comments, issues or PRs are welcomed. Thanks.

• Integrate using CMake's ExternalProject
• Support HDF5
• OpenCL support
• CUDA suuport

.envrc files are for direnv

direnv is an environment variable manager for your shell. It knows how to hook into bash, zsh and fish shell to load or unload environment variables depending on your current directory. This allows to have project-specific environment variables and not clutter the "~/.profile" file.
