Further to my post, here's the log from make HOST_layer23_CONFARGS=--enable-transceiver   http://pastebin.com/DRb1RmJi I double checked that I indeed did checkout the correct sylvain/testing branch. And I can run other osmocom applications like mobile, so it seems I'm having only a problem with the transceiver app. Any help is appreciated.

The host/layer23/src/transceiver folder is created properly.  After running  make HOST_layer23_CONFARGS=--enable-transceiver,  I don't see any transceiver binary in there, so naturally OpenBTS fails when I execute the exec <your path to osmocom-bb>/src/host/layer23/src/transceiver/transceiver 1 script. I also don't see any errors when running make, although it scrolls by so fast it is hard to be sure. Thanks, Miguel
