Hi,
Re SLC6 - this was reported at the ATLAS SIT meeting this afternoon:
Emil reported by email that formal certification has ended and Scientific Linux 6 CERN (SLC6) has been declared as a certified and supported Linux version for production use at CERN as of 1st of February 2012. The current release is Scientific Linux CERN 6.2 released on 1st of February 2012. That is mainly certification on IT side. The experiments still need to test and certify/validate their code on SLC6. Our LCG SLC6 nightly is still setup and running and recently switched to the gcc46 compiler. However there are still underlying problems coming from LCG-AA nightlies on SLC6 which prevents us from going further - currently they have problems building ROOT.
We are investigating how difficult it could be to build SLC5 binaries on the SLC6 platform. That's currently ongoing in the 17.X.0-EXP nightly where we are building i686-slc5-gcc43-opt (32bit OPT with gcc43). Two tags were added in the nightly GaudiPolicy-11-01-12 and DetCommonPolicy-00-00-22 with improvements proposed by Rolf Seuster "append to pp_cppflags -D__USE_XOPEN2K8" only for that kind of build mode (host SLC6 -> target SLC5). Actually most of the packages are now building fine and there are few compilation problems to be looked at more closely and understand and hopefully fixed.
Cheers Steve
