The link for nanomsg1.1.4-Linux.deb on the wiki section is inavailable
The link for the package nanomsg1.1.4-Linux.deb on the wiki section is inavailable,so I got a standard one,but it seems can't work when I used it for ros_ethercat_igh. The error was found in cm_reqpre.h, the symbol nn_sock_cb is not found. So, when the link can be fixed and the nanomsg package can be download?
