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](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. <s>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"
	</s>
	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
