cd $HOME/packages
git clone https://github.com/epics-base/epics-base
cd epics-base
git checkout R7.0.8
make -j
ls -l bin/linux-x86_64/

• build MIDAS with EPICS:
  • set MIDASSYS to $HOME/packages/midas
  • set EPICSSYS to $HOME/packages/epics-base
  • cd $MIDASSYS
  • make cmake
  • check that build/examples/eventbuilder/mevb and build/examples/epics/fe_epics were built

• build ROOTANA
  • make sure ROOTSYS is set and points to a working version of ROOT
  • cd $HOME/packages/rootana
  • make clean; make
  • there should be no errors

• build iris-daqtools
  • cd $HOME/packages/iris-daqtools
  • rm -rf build; mkdir build; cd build; cmake ..; make
  • there should be no errors

• build VME frontends and event builder
  • cd online/src
  • make
  • feairis.exe, fetiris.exe and eb_iris.exe should be built
  • event builder should be run: eb_iris.exe -b BUF

• build DT5740 frontend
  • install CAEN drivers and libraries
  • cd online/dt5740
  • make
  • fedt5740.exe should be built

• build analyzer
