Installation Requirements OpenBTS compiles to a simple Unix binary and does not require special installation. One some systems (Ubuntu), you will need to define LIBS = -lpthread prior to running configure. To run OpenBTS, the following should be installed: Asterisk (http://www.asterisk.org), running SIP on port 5060. libosip2 (http://www.gnu.org/software/osip/) libortp (http://freshmeat.net/projects/ortp/) libusrp (http://gnuradio.org). This is part of the GNURadio installation. It is the only part used by OpenBTS. OpenBTS logs to syslogd as facility LOG_LOCAL7. Please set your /etc/syslog.conf accordingly. For information on specific executables, see tests/README.tests and apps/README.apps. See http://gnuradio.org/redmine/wiki/gnuradio/OpenBTS/BuildingAndRunning for more information.
