[Linphone-developers] linphone: symbol lookup error: /usr/local/lib/liblinphone.so.6: undefined symbol: payload_type_isac

[Hans Lederer]

Hi,

I've had a bit of a difficult time building linphone-3.7.0 from the
sources on my Linux Mint Debian Edition system.
(In README, libvpx-dev libpolarssl-dev libbellesip-dev should added to
the apt-get line!)
(./configure needs the options --enable-zrtp --enable-strict=no for
encryption and to avoid aborting on a warning — should be mentioned in
README!)

Finally, I got it built complete with encryption (the current Debian
packages unfortunately have only version 3.6.2 with a GLX problem and
without encryption), but the following stumps me:

After completing installation according to README, I can start
gtk/linphone from my build folder and it works fine.
But if I start the installed /usr/local/bin/linphone , it crashes with
> address@hidden:~/Temp/Install/linphone-3.7.0$ /usr/local/bin/linphone
> /usr/local/bin/linphone: symbol lookup error: 
> /usr/local/lib/liblinphone.so.6: undefined symbol: payload_type_isac

I checked /usr/local/lib/liblinphone.so.6.0.0 and it is identical with
the built
/home/hans/Temp/Install/linphone-3.7.0/coreapi/.libs/liblinphone.so.6.0.0T
.
I tried to replace it with the built
/home/hans/Temp/Install/linphone-3.7.0/coreapi/.libs/liblinphone.so.6.0.0 
(without
the 'T' — what's the difference anyway?), but to no avail.
I can find the string 'payload_type_isac' three times in both libraries.

What's that??  And how do I fix this now??

(Exactly the same happens on a second LMDE system.)
(On my son's Arch Linux system linphone-3.7.0 was in the repos and runs
fine, but crashes with Segmentation Fault / Speicherzugriffsfehler if I
call him with the MP4V-ES codec — VP8 works.)
