Description Aurora 2013-10-15 12:46:13 UTC

You should add ZRTP support as USE flag. It's a must feature for free communication!

Actually is just disabled. While it's really often enabled on other systems.

Reproducible: Always

It's explicitly disabled in src_configure():

./linphone-3.6.1.ebuild:                --disable-zrtp
./linphone-3.5.2.ebuild:                --disable-zrtp

Comment 2 Andrew Savchenko gentoo-dev

It's disabled for a reason: linphone uses incompatible ZRTP fork.

ZRTP in linphone is not compatible with net-libs/libzrtpcpp we have
in Gentoo. Linphone uses forked libzrtpcpp with changed API available
only in git: git://git.linphone.org/srtp.git
See this issue for more details:
https://github.com/cisco/libsrtp/issues/28

ATM we have only these options:
1) Install libzrtpcpp-linphone and block it with net-libs/libzrtpcpp.
So users will not be able to use either linphone with zrtp or other
packages with zrtp.
2) Bundle forked zrtp into linphone which will violate Gentoo
unbundling policy.
3) Wait for bug 28 to be fixed.

IMO option 3 is the best, option 1 is acceptable, and option 2 is
unacceptable.

--enable-zrtp only has an effect if you build linphone internal ortp.

To get zrtp support in linphone with external ortp, that must be built with zrtp enabled. This requires first that srtp support is enabled, which does not work with stock libsrtp. Either the linphone fork or a patch as per https://github.com/cisco/libsrtp/issues/28 is needed.

This one is not that bad! :D

Any update on this?
ZRTP is an important feature of Linphone...

Comment 6 selim.m.a 2015-09-03 17:07:04 UTC

Their fork of libzrtpcpp is now called bzrtp:
   git://git.linphone.org:bzrtp

This should avoid collisions with the original library.
So all we need is an ebuild for bzrtp and the current version of linphone...

Package removed as a result of vulnerable dependency removal.
