After the changes to the OpenGrok shell script the guide to run OpenGrok on OS X would be as follows:

• download OpenGrok (binary distribution) and unpack it to e.g. /Library/opengrok/

• create install base for OpenGrok

  mkdir -p /var/tmp/base/{src,data,log}
  cp OpenGrok-0.12/logging.properties /var/tmp/base
  

• store your source code /var/tmp/base/src

• download (from http://ctags.sourceforge.net/) install Exuberant ctags

  tar xfz ctags-5.8.tar.gz
  cd ctags-5.8
  ./configure
  make
  sudo make install
  

• download Tomcat 7 (from http://tomcat.apache.org/download-70.cgi) and unpack it to e.g. /Library

  sudo mv apache-tomcat-7.0.52 /Library/

• deploy the war file

  OPENGROK_APP_SERVER=Tomcat \
      EXUBERANT_CTAGS=/usr/local/bin/ctags \
      OPENGROK_TOMCAT_BASE=/Library/apache-tomcat-7.0.52 \
      /Library/opengrok/bin/OpenGrok deploy
  

• start Tomcat
  cd apache-tomcat-7.0.52/bin; ./startup.sh

• index

  EXUBERANT_CTAGS=/usr/local/bin/ctags \
       OPENGROK_DISTRIBUTION_BASE=/Library/opengrok/lib \
       OPENGROK_INSTANCE_BASE=/var/tmp/base \
        /Library/opengrok/bin/OpenGrok index
  

• go to http://localhost:8080/source/ and search the code !
