Installation

Pre-requisite

Required packages for Midas, should be only a few.

• zlib

Standard layout of MIDAS experiment

This layout includes other packages needed for data analysis but not required for acquisition purpose only (noted as **). The online directory is given only as a suggested structure.

/home/exptuser/
  packages/
    root <---- ROOT (64-bit or 32-bit) (**)
    mxml  <---- from MIDAS repository
    midas <---- MIDAS
      linux/{lib,bin}  <---- binaries matching the selected 64-bit/32-bit flavour of ROOT
      linux-m32/{lib,bin}   <---- limited function 32-bit binaries for 32-bit frontend machines, build by "make linux32"
      linux-m64/{lib,bin}   <---- limited function 64-bit binaries (only needed if ROOT and linux/bin are 32-bit)
      linux-crosscompile/{lib,bin}  <---- cross-compiled limited function binaries for PPC and ARM frontends (see Makefile)
  online/
    exptab <---- experiment definition
    {.ODB,.SYSTEM,.SYSMSG,etc}.SHM <---- MIDAS shared memory save files
    src <---- experiment frontend sources
    bin,scripts 
    elog <---- MIDAS elog (**)
    history <---- MIDAS history
    data -> /data/exptname/current <---- symlink to the data directory (**)
/data/exptname/current <---- experiment data directory with ODB save files and MIDAS .mid/.mid.gz data files

Install MIDAS

• mkdir $HOME/packages
• Logout and login again, for .cshrc changes to take effect

• cd $HOME/packages
• git clone https://bitbucket.org/tmidas/midas
• git clone https://bitbucket.org/tmidas/mxml
• (IF BITBUCKET IS DOWN) git clone -v --progress http://daq.triumf.ca/~daqweb/git/mxml.git
• (IF BITBUCKET IS DOWN) git clone -v --progress http://daq.triumf.ca/~daqweb/git/midas.git
• cd midas
• make
• (only if needed) make linux32 ### build the 32-bit MIDAS libraries on 64-bit machine
• ls -l linux/bin/odbedit ### check that odbedit has been created (do not run it yet)

Valid OS list

Midas is compatible with:

* PPC405  
* OSF1
* ultrix
* freeBSD
* Cygwin
* linux
* solaris
* Darwin

external libraries/packages consideration

Midas requires the external library zlib

Environment consideration

(csh)

setenv LANG C
setenv GIT_EDITOR "emacs -nw"
setenv MIDASSYS $HOME/packages/midas
setenv ROOTSYS  $HOME/packages/root
setenv MIDAS_EXPTAB $HOME/online/exptab
setenv PATH .:$MIDASSYS/linux/bin:$PATH
setenv PATH .:$HOME/online/bin:$ROOTSYS/bin:$PATH

(bash)

export LANG=C
export MIDASSYS=$HOME/packages/midas
export PATH=$PATH:$MIDASSYS/linux/bin
export MIDAS_EXPTAB=/home/deap/exptab

# For default remote Midas server to myhost
export MIDAS_SERVER_HOST=myhost00:7071

# For default remote Midas server to a given port
export MIDAS_SERVER_HOST=myhost00:7071

# For no default on remote Midas server
export MIDAS_SERVER_HOST=

# For default Midas experiment
export MIDAS_EXPT_NAME=deap

Midas environment

• MIDASSYS Base directory of the MIDAS package, midas and mxml should be at the same level.
• MIDAS_EXPTAB Experiment definition file
• MIDAS_SERVER_HOST MIDAS host server name for remote midas connections.
