# - http://installing-caffe-the-right-way.wikidot.com/start

# Dependencies
# - XCode 8
# - Also need command line tools for XCode 7.3.1 since CUDA doesn't support XCode 8, which you can get here - https://developer.apple.com/download
#     search for Command_Line_Tools_OS_X_10.11_for_Xcode_7.3.1.dmg
# - CUDA toolkit 8.0 (https://developer.nvidia.com/cuda-toolkit) 
# - Homebrew python, tested against v2.7.12_2
# 

# Install dependiences via brew
# might need to uninstall previous installs
brew tap homebrew/science
brew install -vd snappy leveldb gflags glog szip lmdb
brew install hdf5 opencv
brew upgrade libpng
brew install protobuf boost boost-python

# Setup virtual environment using the brewed python
mkvirtualenv --python /usr/local/bin/python caffe

# Activate virtual environment if not activated already

# Also allow access the global packages

Hello, all goes well but when I did "make -j4 pycaffe" it gives this error and I could not solve it

ld: library not found for -lboost_python
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [.build_release/lib/libcaffe.so.1.0.0] Error 1
