prereqs

The latest FlowVisor, which supports OpenFlow 1.0, is based on java, requiring the following packages:

• ant
• sun-java6-jdk

installation

1. install above-mentioned packages
2. pull from git repository:

    git checkout -b flowvisor-0.6 origin/flowvisor-0.6
   

   we need to take this step to make sure we have the right package.
3. choose the proper version of java with update-alternatives --config java

    root@internal2:/opt/flowvisor# update-alternatives --config java
   There are 2 choices for the alternative java (providing /usr/bin/java).
   
     Selection    Path                                      Priority   Status
   ------------------------------------------------------------
     0            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      auto mode
     1            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      manual mode
   * 2            /usr/lib/jvm/java-6-sun/jre/bin/java       63        manual mode
   

   make sure to have java-6-sun version of java chosen as the alternative as shown above.
4. cd to flowvisor directory; if ./configure doesn't exist, run ./boot.sh

   sh ./boot.sh
   

5. run ./configure
6. run make:

   sudo make CFLAGS="-I/usr/lib/jvm/java-6-sun-1.6.0.20/include -I/usr/lib/jvm/java-6-sun-1.6.0.20/include/linux"
   

   The paths for CFLAGS should be based on what you get if you do a locate jni.h:

   $ locate jni.h
   /usr/lib/jvm/java-6-sun-1.6.0.20/include/jni.h
   

7. run make install
