[Ccrtp-devel] libzrtpcpp ABI breakage - sendDataRTP removed in 0.9.2

[Mark Purcell]

Werner,

It appears that your latest libzrtpcpp breaks it's ABI, but doesn't
bump the soname.  This breaks binary compatibility for binary 
distributions like Debian.

http://bugs.debian.org/cgi-bin/pkgreport.cgi?src=libzrtpcpp

We are going to make a local patch to the Debian package, but you might 
also like to make a more official soname change upstream.

Btw, we have a package tracking system that anyone can subscribe to 
via email and that way you can receive bug reports like this as we do ;-)

The error is caused by API (and ABI) changes in libzrtpcpp version 
0.9.2. The symbol above (sendDataRTP) is removed and seems to be 
replaced with sendDataZRTP, without changing the SONAME.
