Update OTS

2 of 5

There are two components to updating ots...

  1. Updating your source code
    1. This amounts to doing ‘git pull’ in each repository. There is a script shown on the slide 3 that can help with that.
  2. Updating your dependencies
    • Which software products ots depends on are defined by your qualifiers. Changing your qualifiers is shown on slide 4.

​

Note that if you can not setup ots, then you can not compile.

​

Main repository versions should always compile, and usually the develop repository version should compile together IF you select the latest qualifiers.

To update your ots installation...

  • Open up your terminal
    • In the ots Virtual Machine, the Konsole (terminal) icon is in the lower right hand corner of the Virtual Machine, or you right-click on the desktop to find Konsole.
  • Type these commands:
    1. cd [YOUR-DIRECTORY]
      1. [YOUR-DIRECTORY] refers to the path where your localProducts*/ and srcs/ are located.
      2. In the VM, the base folder is called otsdaq-mrb-base (/home/otsdaq/otsdaq-mrb-base)
    2. source setup_ots.sh
    3. UpdateOTS.sh --pullall
      • Note: at the end of the printouts, the available versions and compiler qualifiers are listed. If you want to change to a different version or qualifier, go to the next slide.
    4. Spack install

To change your ots version or compiler qualifiers…

  1. cd <otsdaq-base>
    • In the VM, the base folder is called otsdaq-mrb-base (/home/otsdaq/otsdaq-mrb-base)
  2. source setup_ots.sh
  3. UpdateOTS.sh --pullall
    • This updates your code to the latest develop branch (--fetchall would not change your code)
    • Note: at the end of the printouts, the available versions and compiler qualifiers are listed. If you want to change to a different version or qualifier
    • Choose a version (e.g. v2_05_02) and qualifier (e.g. s96:e19)
  4. mrb newDev -f -v <version> -q <qualifier>
    • e.g. mrb newDev -f -v v2_05_02 -q s96:e19:prof
    • The result will be a new localProducts folders in <otsdaq-base>/
      • e.g. localProducts_otsdaq_demo_v2_05_s96_e19_prof
  5. Delete or move any other localProducts* folders that you do not want to use
  6. Source setup_ots.sh #to re-setup with new dependencies
  7. mrb z; mrbsetenv; mrb b #clean build
  8. You are ready to go!
