    See Software/OACHousekeepingUpgrade#Software_Status for more detailed status.

This week:
  • Fix the ice issue between AOS UAO by simulators
  • Continue working on the power backplane
  • FLAO/ ARGOS TT LUT support


  • Try to rebuild the "mergelogs" tool based on standard default versions of the the Boost library (and other dependencies). This will involve modifications to source code as well. This will provide a path for an automated building/deploying process.
  • Instead of building the AO code on a new VM, I will try to build the existing AO VM with newer versions of GCC (GCC 4.8+). The plan is to install Redhat SCL on the AO VM and use it to switch to different GCC versions. If succeeded, this will pave the way for the AO code to use C++11 features, which will greatly expand the options available.
  • Investigating ways to implement custom special sink in the "spdlog" library that sorts multiple async logging entries according to the log entry timestamp, and then forward the sorted log entries to other standard sinks.
