Build linphone on BBB

BBB.md

BeagleBone Black & Linphone

1. Install what's needed to compile:

   sudo apt-get install automake autoconf gnu-standards gettext build-essential pkg-config git libtool antlr3 libantlr3c-dev intltool
   git clone git://git.linphone.org/polarssl
   git clone git://git.linphone.org/belle-sip
   git clone git://git.linphone.org/linphone --recursive
   

2. Compile polarssl

   ./autogen.sh ./configure make -j2 && sudo make install

3. Install Java from Oracle (important, otherwise ANTLR won't compile correctly the SIP grammar)

   • Go here: http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html and download the JDK for linux (probably Hard Float)

   • Unpack in your HOME and setup the PATH and JAVA_HOME:

     # put this in your ~/.bashrc ideally
     export PATH="/home/user/jdk-x.y.z/bin:$PATH"
     export JAVA_HOME="/home/user/jdk-x.y.z"
     

   • Check that java -version outputs something like this (with the 'TM'):

       java version "1.7.0_51"
       Java(TM) SE Runtime Environment (build 1.7.0_51-b13) 
     

4. Install belle-sip and linphone dependencies

    sudo aptitude install libswscale-dev libavcodec-dev libv4l-dev libglew1.6-dev libxml2-dev libgsm1-dev libsqlite3-dev libupnp-dev libsdl1.2-dev
   

5. Get libvpx from Google and compile it yourself, so that you get the NEON and other optimizations

    git clone https://chromium.googlesource.com/webm/libvpx -b v1.3.0
    cd libvpx
    CC=cc AR=ar AS=as LD=gcc CXX=g++ ./configure --enable-vp8 --target=armv7-linux-gcc --disable-examples --disable-docs --enable-error-concealment --enable-realtime-only --enable-spatial-resampling --enable-multithread --disable-vp9 --enable-pic 
    make -j2
    sudo make install
   

6. Get speex from linphone and compile it with NEON optimizations

    git clone git://git.linphone.org/speex
    cd speex && ./autogen.sh
    ./configure --enable-armv7neon-asm --with-pic --enable-fixed-point --disable-oggtest CFLAGS="-march=armv7-a -mfloat-abi=hard -mfpu=neon -mtune=cortex-a8 -O3" --disable-ogg
    make -j2 &&	sudo make install
   

7. Compile and install belle-sip

    ./autogen.sh
    ./configure
    make && sudo make install
    # optional: perform belle-sip tests
    cd tester && ./belle_sip_tester
   

8. Compile and install linphone

    ./autogen.sh
    ./configure --disable-x11 --enable-gtk_ui=no --disable-xv --enable-sdl
    # Note: Wno-error is here because otherwise mediastreamer complains about not used functions
    make V=1 CFLAGS="-Wno-error" && sudo make install
   

9. Test that linphone passes the tests

    cd tester && ./liblinphone_tester
   

10. To enable video: install omapfb driver

    See http://blog.csdn.net/amd123linux/article/details/11738753 :

    sudo apt-get install xserver-xorg-video-omap3
    sudo reboot
    cat /var/log/Xorg.0.log | grep omapfb
    xvinfo -display :0.0 # should show "OMAP XV adaptor"
    

    Not supported by BBB....

11. Setup video output in linphonerc

    This will force the video display to use the SDL output

    #launch linphone once to create it
    linphonec
    # type quit
    
    #edit the linphonerc file
    nano ~/.linphonerc
    
    # find the [video] section and put or replace:
    displaytype=MSVideouOut
