Install notes

Based on http://prjemian.github.io/epicspi/
This assumes you have a clean install of raspbian (I'm using 2015-05-05)

EPICS Base

• Boot into raspbian and make sure you have a network connections

• Log in as user: pi

• Set up the date (if it's wrong!)

  sudo dpkg-reconfigure tzdata
  

• Make a new user: enge (make whatever you want for the password)

  sudo adduser --home /home/enge enge
  

• Add that user to the sudoers list

  sudo adduser enge sudo
  sudo adduser enge dialout
  

• Log out and then in as that user

• Make the file structure

  mkdir bin
  mkdir extensions
  mkdir project
  mkdir synApps
  

• Download and untar the EPICS base package

  wget http://www.aps.anl.gov/epics/download/base/base-3.15.3.tar.gz 
  tar -xzvf base-3.15.3.tar.gz
  ln -s base-3.15.3 base
  

• Paste the following into .bashrc

  ######################################################################
  ##  EPICS
  ######################################################################
  
  ## Base
  export EPICS_ROOT=/home/enge
  export EPICS_BASE=${EPICS_ROOT}/base/
  export EPICS_HOST_ARCH=`${EPICS_BASE}/startup/EpicsHostArch`
  export EPICS_BASE_BIN=${EPICS_BASE}/bin/${EPICS_HOST_ARCH}
  export EPICS_BASE_LIB=${EPICS_BASE}/lib/${EPICS_HOST_ARCH}
  if [ "" = "${LD_LIBRARY_PATH}" ]; then
      export LD_LIBRARY_PATH=${EPICS_BASE_LIB}
  else
      export LD_LIBRARY_PATH=${EPICS_BASE_LIB}:${LD_LIBRARY_PATH}
  fi
  export PATH=${PATH}:${EPICS_BASE_BIN}
  
  ## EPICS Extensions
  export EPICS_EXT=${EPICS_ROOT}/extensions
  export EPICS_EXT_BIN=${EPICS_EXT}/bin/${EPICS_HOST_ARCH}
  export EPICS_EXT_LIB=${EPICS_EXT}/lib/${EPICS_HOST_ARCH}
  if [ "" = "${LD_LIBRARY_PATH}" ]; then
      export LD_LIBRARY_PATH=${EPICS_EXT_LIB}
  else
      export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${EPICS_BASE_LIB}
  fi
  export EPICS_SYNAPPS_BASE=${EPICS_ROOT}/synApps
  export EPICS_SYNAPPS_BIN=${EPICS_SYNAPPS_BASE}/support/utils
  export PATH=${PATH}:${EPICS_EXT_BIN}:${EPICS_SYNAPPS_BIN}
  

• Load it

  source ~/.bashrc
  

• Compile EPICS

  cd base
  make -j3
  

• Buy and drink some coffee

• Once finished, check that it works

  softIoc
  

• Epics should have started. Now run the IOC

  iocInit
  

• You should see something that looks like

  epics> iocInit  
  Starting iocInit

synApps (needed for streamdevice and serial connections)

• Get the extensions and msi first

  cd ~
  wget http://www.aps.anl.gov/epics/download/extensions/extensionsTop_20120904.tar.gz
  tar -xzvf extensionsTop_20120904.tar.gz
  wget http://www.aps.anl.gov/epics/download/extensions/msi1-7.tar.gz
  cd extensions/src
  tar -xzvf ../../msi1-7.tar.gz
  cd msi1-7
  make
  

• Install re2c (I don't know what it's for)

  sudo apt-get install re2c
  

• Download and unzip synApps

  cd ~
  wget http://www.aps.anl.gov/bcda/synApps/tar/synApps_5_8.tar.gz
  tar -xzvf synApps_5_8.tar.gz
  ln -s synApps_5_8 synApps
  

• We don't need all the junk included

  cd synApps/support/configure
  emacs RELEASE
  

• Edit the SUPPORT line

  SUPPORT=/home/enge/synApps/support
