Core Minutes 5/25/2010

• FSSC: (John) Nothing to report this week.

• Pass 7: (Tom G.) Nothing to report concerning reprocessing.

• Core talk:

  • Yet Another Platform (Heather) Snow leopard has been installed on bldmac02. Kim is building externals. He will consult Eric Winter's notes for help with the more difficult ones, in particular Xerces.

  • Windows RM builds (Heather) are back! There were two problems:

    • Navid determined one right away: the last successful windows CMT build had been a branch tag. The code handling LATEST didn't know how to deal with that and went into an infinite loop. Navid has put in a fix for this condition.
    • Somehow the ssh key file got deleted; we have no idea how or by whom. It has since been reinstalled.

  • ROOT 5.26 and L1 (Heather) wonders whether we could move L1proc to ROOT v5.26 now that monitoring apps are happy. (Warren) thinks we could move pretty soon.

  • u09 (Heather) Tom G. found a Gbyte which can readily be reclaimed.

  • SCons topics (Joanne) has brought SCons workbook pages up to date. The first two (SCons: An Introduction and making Builds with SCons) were completed before Chuck left on vacation, hence are now visible from the workbook. The third page, SCons fro Developers, is fully updated in CVS but only a fraction of those updates were done before Chuck left. Much of the workbook version is misleading or just plain wrong. Anyone wishing to get at the up-to-date CVS version before Chuck's return should ask me for instructions. I also updated the GoGui instructions. The contents are now correct, but incomplete. The instructions say nothing about how to use Studio from GoGui.

    (Joanne) One of the issues Toby raised, now that we're coming down to the wire, is the creation of .pyc files, the compiled version of python source. For typical python applications it would be created the first time the code is imported. However, users wishing to run against our RM builds at SLAC do not usually have write access to the build area. They can still use the build, but the .py files run significantly more slowly than the corresponding .pyc. One way around this would be to create the .pyc files as part of the build process.

    (Joanne) Nicola Omodei uncovered two problems with our method of generating ostensibly dynamically loadable root libraries with SCons:

    • If the package include files reference includes from one of our externals, the rootcint command fails. We need to find a way to add include paths for the externals to that command.
    • When he tried loading librootIrfLoader.so (SCons build) from ROOT, the load failed. The same library as built by CMT loads successfully. (Heather) volunteers to look at this one.

    (Tom) has been looking into creating distributions as part of Windows builds, as is already the case for Linux.

    (Tom) Automatic RM HEAD and tagged release builds are now enabled for rhel5 64-bit builds (Optimized and Debug for Release tags; debug only for HEAD).

    (Tom) Other projects include updating the deleteBuild script (which may involve modifications to the eraseBuild script it calls, as well) and investigating email notifications from RM. According to Navid they should be turned on (in fact, there is no way to turn them off), so the first thing to find out is whether they are being sent and, if not, why not.

    (David) is trying out the the SCons ST build. He believes he can make necessary adaptations within the next few days.
