[Linphone-users] oRTP: undefined symbols

[alekcejk]

Hi,

I built ortp-0.20.0 against libzrtpcpp-2.1.1
https://github.com/downloads/wernerd/ZRTPCPP/libzrtpcpp-2.1.1.tar.bz2

libzrtpcpp-2.1.1 released yesterday and its code looks very
close to sources from git://git.linphone.org/zrtpcpp.git

But there are undefined symbol shown by ldd:

Is there way to fix symbol lookup errors?
