Re: [Linphone-users] ZRTP on Android

[Daniel Muller]

Thanks Guillaume,

this moves me a bit further, I tried to follow the instructions in submodules/linphone/README.zrtp

first thing I noticed, that libzrtpcpp as well as srtp folders exist already in the submodules/externals/

I did not try to replace them with the new ones, I only patched the files (supposing they are there because it's been tested to work with them).

The bulding gives some output, and first errors that occur are
     [exec] /opt/android-ndk-r8e/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: ./obj/local/armeabi-v7a/libopencoreamr.a(wrapper.o): in function Decoder_Interface_init:jni/..//submodules/externals/build/opencore-amr/../../opencore-amr/amrnb/wrapper.cpp:30: error: undefined reference to 'GSMInitDecode'
     [exec] /opt/android-ndk-r8e/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: ./obj/local/armeabi-v7a/libopencoreamr.a(wrapper.o): in function Decoder_Interface_exit:jni/..//submodules/externals/build/opencore-amr/../../opencore-amr/amrnb/wrapper.cpp:35: error: undefined reference to 'GSMDecodeFrameExit'

On the other hand I wanted also to try using the libzrtpcpp-2.0.0 as in the readme
I need to remove ZrtpPacketRelayAck,  ZrtpPacketSASrelay from libzrtpcpp/Android.mk in order to pass further

Also ekt from srtp..

Edit zrtp.h in ortp folder to change path for include <include/srtp.h>

After that the next error proved libzrtpcpp-2.0.0 is too old for this, as ortp expects some parametres that are obviously newer features of zrtp..

To complete the information my linphone-android comes from the git few days ago

Seems like some GSM module should be turned on too.. How and which?

Hi,

Have you checked readme for how to compile ZRTP support?

Enable traces and check adb logcat.

Cheers,
Guillaume
