Undefined reference to boost::thread functions when building Caffe

问题

I'm trying to compile Caffe on Ubuntu 14.04. I keep getting undefined reference to 'boost::thread::...' errors in the linking phase.

I searched the web and found many people with similar problems and tried pretty much everything I found (too many to list here).

I tried among other things installing boost using apt-get:

sudo apt-get install libboost-python-dev
sudo apt-get install libboost-all-dev

Also tried building and installing from the sources:

sudo ./b2 --threading=multi -j4 --with-thread install
sudo ./b2 --threading=multi -j4 --with-thread install -a link=static

The errors I keep getting are:

.build_release/lib/libcaffe.so: undefined reference to `boost::thread::~thread()'
