libradsec-0.0.1-dev is a non-working RADIUS library doing UDP, TCP, TLS and DTLS. Canonical pickup point: http://git.nordu.net/?p=radsecproxy.git;a=shortlog;h=refs/heads/libradsec libradsec depends on - libradius from the FreeRADIUS freeradius-server - libevent2 - libconfuse - openssl (if configured with tls or dtls support) To compile the library and the examples, do something like sh autogen.sh && ./configure && make If any of the libraries are not found, try setting environment variable LDFLAGS at configure time. LDFLAGS="-L/usr/lib/freeradius -L/usr/local/lib" ./configure The parts of the library which has been tested has been so on Linux (Ubuntu 10.04) with libfreeradius2 (2.1.8+dfsg-1ubuntu1), libconfuse0 (2.6-2) and libevent-2.0.7-rc-dev (http://monkey.org/~provos/). The file HACKING contains more detailed info on the state of the various parts of the library.
