Hi, I just upgraded my box to Ubuntu 11.10 and successfully compiled GNURadio 3.4.2, however I'm unable to build osmo-tetra (output below). I had it working on my Ubuntu 10.10 box with GNURadio 3.1 or 3.2 (can't remember exactly now). The latest libosmocore has been compiled and installed. Trying to get closer to the issue I also experimented with the libosmocore/osmo-tetra source versions available when I made the successful install, but I'm getting the same error. I'm not sure whether I'm simply missing some step or I'm facing an incompatibility. Any hint?
