wview Quick Start Guide for Macintosh

February 5, 2006

Purpose

Mac OSX Requirements

• xcode - development tools including gcc required to build source packages - see http://developer.apple.com/tools/xcode/ to download the dmg installer
  
  
• DarwinPorts - Darwin package management system - used to install the library prerequisites listed below - see http://darwinports.opendarwin.org/getdp/ to download the dmg installer - once installed, add /opt/local/bin to your path by adding the following line to your ~/.profile file: "export PATH=$PATH:/opt/local/bin" - then execute the following:
  
  sudo port -d selfupdate (this may take a while)
  sudo port install gd2 (this should install the zlib and libpng prerequisites automagically)
  
  Note: All wview binaries and scripts will be found at /opt/local/bin instead of /usr/local/bin, so all instructions in the User Manual should have "/usr/local" replaced with "/opt/local" for Mac installs
  
  
• radlib - rapid application development library - must be installed - http://www.radlib.teel.ws
  
  Note: Mac OSX installs will use a configure prefix of "/opt/local" for radlib and wview - use the "--prefix=/opt/local" argument to the configure script for both radlib and wview
  
  
• libcurl - "C" URL HTTP library - optional, required for Weather Underground - http://curl.haxx.se/libcurl/
  
  DarwinPorts Install: sudo port install curl

System Requirements

• Sufficient Kernel Share Memory - check the following line in the /etc/rc file, making sure the two sizes (shmmax and shmall) are similar in magnitude to this line:
  sysctl -w kern.sysv.shmmax=536870912 kern.sysv.shmmin=1 kern.sysv.shmmni=32 kern.sysv.shmseg=8 kern.sysv.shmall=131072
• ntp/xntp - Network Time Protocol - a configured and functional NTP daemon should be enabled on the host system to keep system and weather station time accurate
• apache - in order to serve your weather site to the world, an http server is required - other http servers will work too. If you are going to export your site to another server or to your ISP account site, then an http server is not required on the wview server
• Serial/Ethernet/USB port - an available interface port is required to connect to the weather station

Weather Station - one of the following:

• Vantage Pro or Vantage Pro2 Weather Station with Console
  
  • --enable-station-vpro
  • WeatherLink for Vantage Pro or Pro2, Macintosh Version - the java software is not required, but this is the only way to obtain the USB-to-Serial convertor, driver and serial data logger
    
    Optionally, you can use the windows version with the serial data logger if you obtain separately a USB-to-Serial convertor with a MacOSX compatible driver - the Prolific chipset PL-2303 and driver have been confirmed to work with wview on a Mac Mini - Note: USB data loggers are NOT supported by MacOSX (in particular, there is no CP2101 driver for Darwin/FreeBSD) - unless you have a serial port on your Mac, you must use a USB-to-Serial adapter connected to a Weatherlink serial data logger (or just use the adapter provided with the Macintosh version of Weatherlink)
• Vaisala WXT-510
  
  • --enable-station-wxt510
• Station Simulator (for demos and testing)
  
  • --enable-station-sim

Install Procedure

      Note: execute these commands in a terminal session while logged into an account 
            with administration privileges - the sudo command requires you to enter your 
            password before it will execute the command following it.
      
      1)  Extract the radlib distribution: 

          tar zxvf radlib-x.y.z.tar.gz
      
      2)  Configure the distribution: 

          cd radlib-x.y.z
          ./configure --prefix=/opt/local
      
      3)  Build/install radlib: 

          sudo make install
      
      4)  Extract the wview distribution: 

          tar zxvf wview-x.y.z.tar.gz
      
      5)  Configure the distribution: 

          cd wview-x.y.z
          ./configure --prefix=/opt/local --enable-station-[type]
      
      6)  Build/install wview: 

          sudo make install
      
      7)  If a first time wview install, copy the default run environment:

          sudo make install-env

      8)  If a new Vantage Pro station, use the on-screen console configuration 
          wizard
      
      9)  Configure wview: 

          sudo /opt/local/bin/wviewconfig
          
          Note: If you are using the USB-to-Serial convertor and driver supplied 
                with the Weatherlink for Mac package, your Physical Interface is 
                "serial". This is what you should specify for the first question, not 
                the actual device name (/dev/tty.SLAB_USBtoUART) - this should be 
                given in the second question after specifying "serial" for the first.
      
      10) If a first time wview install, copy the example startup directory for 
          wview to /Library/StartupItems:

          sudo cp -R ./examples/MacOSX/wview /Library/StartupItems
          sudo chmod -R 755 /Library/StartupItems/wview
          sudo chmod -x /Library/StartupItems/wview/StartupParameters.plist
          sudo chown -R root:wheel /Library/StartupItems/wview

          Now wview should be started when you boot your Mac.

      11) Run wview: 

          sudo /sbin/SystemStarter start "wview"
          
          Note: You can stop or restart wview as follows:
          sudo /sbin/SystemStarter stop "wview"
          sudo /sbin/SystemStarter restart "wview"
      
      12) See wview startup and run logs:

          sudo tail -n 100 -f /var/log/system.log
          
          Note: Unless you configured wview to include ftp, ssh, alarms or CWOP 
                support, these daemons will start up, complain about not finding 
                their config files, then exit. This is normal behavior. wviewconfig 
                disables these options by naming the config files to something 
                other than what the daemons are expecting so they will exit when 
                they try to initialize. Don't let this bother you.

      13) Confirm proper operation:

          sudo ps aux | grep wv
          (you should see at least "wviewd" - maybe others if you enabled them)

          sudo ps aux | grep htmlgend
          (you should see "htmlgend")

          You should see the log message "doing initial html generation now..." 
          at the end of the wview initialization log messages.

          ls -al /var/wview/img/index.html
          (you should see the file listed)

          Open /var/wview/img/index.html with your favorite browser - this is your 
          new wview homepage.
