.build_release/lib/libcaffe.so: undefined reference to `boost::python::import(boost::python::str)'

I get this error with Python2.7 and Ubuntu15.10:

jalal@klein:~/computer_vision/py-faster-rcnn/caffe-fast-rcnn$ make -j8 && make pycaffe

How can I fix this? I have boost installed. From https://github.com/rbgirshick/py-faster-rcnn

I already have run:

sudo apt-get install build-essential g++ python-dev autotools-dev libicu-dev build-essential libbz2-dev libboost-all-dev

And:

sudo apt-get install libboost-python-dev

Installing Boost from the source worked for me! After downloading the Boost source code from its official website:

sudo ./bootstrap.sh --prefix=/usr/local
./b2
sudo ./b2 install
