Hi,

Can you confirm boost libs were installed in /usr/local/lib?

Or maybe you built boost using layout=versioned?

That will create files having version number and arch information in 
their names. In this scenario using plain `-lboost_xxx.so` would not 
work as you would have to use the whole library name

`layout=versioned` is the default behavior. If you want plain filenames 
like `libbboost_system.so` you must use `layout=system`.

In the other hand, you may want to just skip the pain of compiling boost 
yourself and install `libboost-all-dev` with apt-get (this will install 
boost 1.74).
