[Halld-offline] Calibration exception -- missing file for magnetic field?

Thu Mar 6 12:44:20 EST 2014

Hi David,

So I finally got around to trying to get this code running for my student but still no luck...

We upgraded to jana_0.7.1p1 and ccdb_0.09 then tried to build the sim-recon-dc-2.2 tagged release.  

(By the way is there anything special about the dc releases?  Are the just like ordinary tagged releases with a different naming scheme?  I noticed in the RELEASE that the last dated tag version uses older jana and ccdb.)

First we got caught by the fact that the installation scheme for JANA is now different.  I remember now this was announced.  We read the directions and ran the setenv script in the JANA install.

There also seems to be some collisions between the gluex env setup that is in build_scripts and the JANA setup.  It is not clear what to set where.  I tried for example to set the JANA_CALIB_URL based on CCDB_CONNECTION to point to the sqlite file downloaded from the link on Wiki, but found it was overwritten by one of the scripts.  (This may be due to the fact that we didn't svn update in build_scripts.)  So I had to set it at the very end of .tcshrc.

Anyway... after about 50 minutes we finally got everything compiled.  (The compile itself went well thanks to scons and a 12-core machine).

However, trying to run hdview2 on a file then generated a segfault.  The stack trace and environment is attached.  Do you have any ideas on how to debug further?

Matt

You now have to get the constants from the CCDB either via SQLite file (recommended for your current use case) or MySQL. An SQLite file is generated every night now from the MySQL database. These can be found on the JLab CUE here:
