Hello there Frank,<br>
<br>
That's estrange because TLSv1_server_method is the default TLS method that<br>
should be available...maybe some build option of your libssl disabled it on<br>
your raspbian? <br>
<br>
It could also happen that somehow ../src/<a href="http://libnopoll.la" target="_blank">libnopoll.la</a> is not exported the -lssl<br>
and -lcrypto to the regression test binaries being created :-?<br>
<br>
If that is the case, check the following release that includes explicit references<br>
to -lssl and -lcrypt flags: <a href="http://www.aspl.es/nopoll/downloads/nopoll-0.2.9.b184.tar.gz" target="_blank">http://www.aspl.es/nopoll/downloads/nopoll-0.2.9.b184.tar.gz</a><br>
<br>
If is not, check why your platform is not linking TLSv1_server_method by creating<br>
a simple main.c file calling to that function as shown here: <br>
