[OG LESS]

What file do I need to link to, to get rid of the following error (make)?:

undefined reference to `gr_msg_accepter::post(boost::intrusive_ptr<pmt::pmt_base>)'

Alot of similar errors are removed when linking the file /usr/lib/libgnuradio-core.la, however, I don't know why this one isn't going anyway?
