== tdaq-common ==
The AtlasCore Offline project depends on the tdaq-common TDAQ project.
The latter can be found, e.g., on AFS

{{{/afs/cern.ch/atlas/project/tdaq/cmt/tdaq-common/}}}

An example setup for the x86_64-slc6-gcc46-opt platform build on an SL6 machine can be:

{{{
$ . /afs/cern.ch/sw/contrib/CMT/v1r25/mgr/setup.sh
$ export CMTCONFIG=x86_64-slc6-gcc46-opt
$ export CMTSITE=CERN
$ . /afs/cern.ch/sw/lcg/contrib/gcc/4.6.2/x86_64-slc6-gcc46-opt/setup.sh
}}}

Then, assuming that the source code is available in the current directory:

{{{
$ cd tdaq-common/tdaq-common-01-20-04/TDAQCRelease/cmt
$ { \time cmt br "make VERBOSE=1 && make inst VERBOSE=1"; } >& cmt-br-make-make-inst.log&
$ { \time cmt br -make -j1 -k check VERBOSE=1; } >& cmt-br-make-j1-k-check.log&
}}}

Another Make target is rpm.

I have installed tdaq-common into /exp/si/cmtng/tdaq/tdaq-common/tdaq-common-01-20-04

I have created a setup script /exp/si/cmtng/tdaq/setup.csh which contains:

{{{
source /afs/cern.ch/sw/contrib/CMT/v1r25/mgr/setup.csh
setenv CMTCONFIG x86_64-slc6-gcc46-opt
setenv CMTSITE CERN
source /afs/cern.ch/sw/lcg/contrib/gcc/4.6.2/x86_64-slc6-gcc46-opt/setup.csh
}}}

My session:

{{{
cd /exp/si/cmtng/tdaq/tdaq-common/tdaq-common-01-20-04/TDAQCRelease/cmt
setenv CMTPATH /exp/si/cmtng/tdaq/tdaq-common/tdaq-common-01-20-04
cmt config
cmt show uses
cmt br cmt show uses
cmt br "make VERBOSE=1" > & cmt-br-make-make.log
}}}

Somme immediate comments on requirements of tdaq (made with Antoine & Sébastien)

Indeed packages are either:

  1. simple packages with mainly libraries & applications
  1. of non standard Policy packages

=== Comments: ===
  * Simple packages should be converted into Yaml easily
  * Policy packages require manual construction of hwaf "functions"
  * Remains the question of "tags"
    * what is the replacement concept? ("variant"?)
    * there are "automatic" variants (deduced from the platform/hardware/... introspection) - how to express them 
    * and non automatic variants (eg with or without graphic)
    * how to implement in hwaf
    * how to express in yaml (or more generally in declarative language)
    * how to express the different forms of macro/set values?
    
  * Questions:
    * how to express the Yaml form of path/path_append/path_prepend/path_remove

=== Conversion from requirements to xml ===
