Installation and setup of an Intel Edison with Ubilinux + MRAA + UMP + Java (November 2015)

edison-ubilinux-mraa-java

The MRAA/UMP Java libs come prebuilt with the default distro that Intel provides. 
But if you wanna do ubilinux, the following may work.

1) Download Ubilinux and flash to Edison (2 decent guides below)

  http://www.emutexlabs.com/ubilinux/29-ubilinux/218-ubilinux-installation-instructions-for-intel-edison
  * Once you have the image loaded with wifi and ssh working, go to step 2 *
  
2) Manually install Java
  a) http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
  b) grab jdk-8xxx-linux-i586 (xxx being latest stable version)
  c) move it to the edison
    using sftp: 
      sftp root@192.168.0.[edisonip]
      cd /root
      put jdk-8xxx-linux-i586.gz
      exit
    using sdcard (this was using sparkfun microsd shield)
      put downloaded java archive on sdcard
      reboot edison with sdcard inserted
      ssh root@192.168.0.[edisonip]
      mount /dev/mmcblk1p1 /mnt
      mv /mnt/jdk-8xxx-linux-i586.gz /root/jdk-8xxx-linux-i586.gz
  d) extract goodies
    ssh root@192.168.0.[edisonip]
    cd /root
    umask 0
    tar xvf jdk-8xxx-linux-i586.gz
  e) move goodies to standard place
    mv jdk1.8.0_xx /usr/lib/jvm/oracle_jdk8
  f) create environment vars
    vi /etc/profile.d/oraclejdk.sh
    (add the following)
    export J2REDIR=/usr/lib/jvm/oracle_jdk8/jre
	  export PATH=$PATH:/usr/lib/jvm/oracle_jdk8/bin:/usr/lib/jvm/oracle_jdk8/db/bin:/usr/lib/jvm/oracle_jdk8/jre/bin
	  export JAVA_HOME=/usr/lib/jvm/oracle_jdk8
	  export DERBY_HOME=/usr/lib/jvm/oracle_jdk8/db
	  (exit vi :wq<enter>)
	  source /etc/profile.d/oraclejdk.sh
	g) test java
	  java -version

3) Install/Build MRAA/UMP
  a) install reqs
    apt-get install git (and any other prereqs, swig was pre-installed on lates ubilinux)
    apt-get install cmake-data=2.8.11.1-1~bpo70+1 (ump requires this specific version)
    apt-get install cmake=2.8.11.1-1~bpo70+1
  c) install MRAA (board lib)
    cd /root
    git clone https://github.com/intel-iot-devkit/mraa.git
    mkdir mraa/build
    cd mraa/build
    cmake -DBUILDSWIGNODE=OFF -DBUILDSWIGJAVA=ON -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
    make
    make install
  d) install UMP (sensor libs)
    cd /root
    git clone https://github.com/intel-iot-devkit/upm.git
    export PKG_CONFIG_PATH=/usr/lib/i386-linux-gnu/pkgconfig
    export CPLUS_INCLUDE_PATH=/usr/include
    export LIBRARY_PATH=/usr/lib
    apt-get install cmake-data=2.8.11.1-1~bpo70+1
    apt-get install cmake=2.8.11.1-1~bpo70+1
    cmake -DBUILDSWIGNODE=OFF -DBUILDSWIGJAVA=ON -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
    make (this takes ~1hr)
  e) test MRAA
    export LD_LIBRARY_PATH=/usr/lib/java
    cd /usr/share/mraa/examples/java
    javac -cp /usr/lib/java/mraa.jar:. Example.java
    java -cp /usr/lib/java/mraa.jar:. Example
