=====================================================================
AR presented the status of the ongoing activities in the LCG Generator
Services subproject since the last planning meeting (28 November 2008),
and the plan of work for the next 6 months.
Comments to the slides
======================
The main proposal for the next 6 months (see slide #10), i.e.
to build all new versions in GENSER with autotools only, has
been approved.
We report below the few questions and comments on this subject.
1) DG commented that autotools have another major advantage
(besides portability in most platforms): they allow more
easily the packaging and distribution of code via standard
Linux tool like rpm and yum .
This is not necessarily a task for GENSER, but it allows
interested people to eventually work on it.
2) GC asked confirmation that the Mac OS X platform will be
supported (besides Window, for selected generators), as
required by LHCb (see slide #6, third (last) point).
AR agreed and emphasized that this is one of the benefit
of adopting autotools.
AB (via email after the meeting) reminded that autotools
doesn't always do everything right for Mac OS
(particular attention should be paid to the linker option
flags), but he would expect that for the Fortran generators
it'll be fine.
3) JK asked whether with autotools will be still possible to
build a single version of a generator, without anything
else.
GC also asked whether the libraries in GENSER will be
distributed on AFS in exactly the same way as now.
AR replied positively, commenting that the goal is that
users should not be affected at all by the transition
from the current building system to the new one based on
autotools.
