Trying to get op25 on a new latop that has 12.04 (tried to install 10.04 but network drivers wont load). Installed with the : http://op25.osmocom.org/trac/wiki.png/wiki/InstallInstructionsPage First issue was math header was not found, included it in op25/gr-op25_repeater/lib/gardner_costas_cc_impl.cc The with the new gcc naowing became an error so I disabled it with make CXX_FLAGS="-Wno-narrowing" Which got me to what seems to be libboost cant be linked.
