Do you have boost_python3 installed and on your path?

The error says:

/usr/bin/ld: cannot find -lboost_python3

From https://github.com/BVLC/caffe/blob/master/CONTRIBUTING.md:

_Please do not post usage, installation, or modeling questions, or other requests for help to Issues._
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.

FYI boost doesn't provide the symlink that you'd expect. Either link to the correct version directly like -lboost_python-py34 or create the symlink yourself:

ln -s /usr/lib/x86_64-linux-gnu/libboost_python-py34.so /usr/lib/x86_64-linux-gnu/libboost_python3.so

For Ubuntu 16.04 LTS:
Mind the shift from Python 3.4 to Python 3.5, accordingly:

ln -s /usr/lib/x86_64-linux-gnu/libboost_python-py35.so /usr/lib/x86_64-linux-gnu/libboost_python3.so

Can you tell me how you solve your problem mentioned above?I am looking forward to receive your reply. @habemen

missing dependencies

For_ Ubuntu 16.04 LTS:
apt search libboost
apt-get install libboost-all-dev

According to your version:
ln -s /usr/lib/x86_64-linux-gnu/libboost_python-py35.so.1.58.0 /usr/local/lib/libboost_python3.so
