The bi-weekly meeting of the LHC librarians and SPI group

Attendees: Emil, Andreas, Hubert, Stefan News === LCG 53d released - details at https://twiki.cern.ch/twiki/bin/view/SPI/LcgConfiguration53d - several problems - Rebuild needed for RELAX 1.1.9 -> 1.1.9a (because of CLHEP version contained in their library names) - COOL headers missing -> fixed now Round Table === LHCb --- - would like to use the dev, before doing that fixes in POOL will be needed to adapt to the new version of ROOT Atlas --- - Waiting for Gaudi v19r5 in order to test LCG 53d - Also wants to use ROOT > 5.17.xx from the nightlies CMS --- - ROOT 5.17.xx contains fixes for the file issues which were reported by CMS. Aob === - The question arose whether testing gcc 4.2.2 for performance issues is envisaged. For the time being this is not planned. - Together with a new LCG 54 configuration which will introduce a version change in ROOT, it might be good to also check versions of external packages e.g. - zlib -> speedup with latest version - expat 1.95 -> 2.x - qt 3.x -> 4.x ? - mysql 5.18 -> 5.20 - gsl -> new version ? - CMS is looking into effective-c++ flag for gcc, this might be also interesting for LCG/AA software to turn on, to see how compliant it was.
