GDML is switched off in NuWa ¶

libG4gdml.so is built with geant4 if the switch is ON NuWa-trunk/lcgcmt/LCG_Builders/geant4/cmt/requirements:

90 set G4LIB_BUILD_GDML "1" \
91     dayabay ""
92
93 set G4LIB_USE_GDML "1" \
94     dayabay ""

Geant4 level manual GDML build ¶

Subsequent Geant4Py build misses libG4persistency ¶

Need to invoke the global target to make that:

GDML Manual Install lib and includes ¶

[blyth@belle7 gdml]$  cp ../../../lib/Linux-g++/libG4gdml.so $DYB/NuWa-trunk/../external/geant4/4.9.2.p01/i686-slc5-gcc41-dbg/lib/libG4gdml.so

[blyth@belle7 gdml]$ cp include/* $DYB/external/geant4/4.9.2.p01/i686-slc5-gcc41-dbg/include/

GDML via GiGa ¶

google:geant4 giga gdml
- http://svn.cern.ch/guest/lhcb/Gauss/trunk/Sim/LbGDML/options/GDMLWriter.opts
- http://svn.cern.ch/guest/lhcb/packages/trunk/Sim/GDMLG4Writer/src/GDMLRunAction.cpp

Find something relevant. API has changed, but principal is the same. Mostly GiGa glue code.

[blyth@belle7 NuWa-trunk]$ find . -name '*.cpp' -exec grep -l RunAction {} \;
./lhcb/Sim/GaussTools/src/Components/GiGaRunActionCommand.cpp
./lhcb/Sim/GaussTools/src/Components/TrCutsRunAction.cpp

./lhcb/Sim/GiGa/src/component/GiGaIGiGaSetUpSvc.cpp
./lhcb/Sim/GiGa/src/component/GiGaRunManager.cpp
[blyth@belle7 NuWa-trunk]$

Identify something similar lhcb/Sim/GaussTools/src/Components/GiGaRunActionCommand.cpp to base GiGaRunActionGDML upon and piggyback the CMT controlled build, from:

[blyth@belle7 cmt]$ pwd
/data1/env/local/dyb/NuWa-trunk/lhcb/Sim/GaussTools/cmt

Manually install G4DAE includes into NuWa/G4 location ¶

perhaps a G4 dybinst patch is the eay to go for G4DAE, rather than this manual juggling

blyth@belle7 cmt]$ t dae-install-inc
dae-install-inc is a function
dae-install-inc ()
{
    nuwa-;
    local blib=$(env-home)/geant4/geometry/DAE/include;
    local ilib=$(nuwa-g4-idir)/include;
    ls --color=tty -l $blib;
    local cmd="cp $blib/G4DAE*.{hh,icc} $ilib/";
    echo "$cmd";
    eval $cmd;
    ls --color=tty -l $ilib/G4DAE*
}

Build modified GaussTools ¶

With G4GDML and G4DAE switched on:

[blyth@belle7 cmt]$ svn diff

Perform Export creating 3.2M file ¶

# --- GDML geometry export ---------------------------------
#

grag = GiGaRunActionGDML("GiGa.GiGaRunActionGDML")

Perform the export:

[blyth@belle7 gdml]$ cd ~/e/geant4/geometry/gdml

NuWa integration GDML export functionality ¶

GiGaRunActionGDML is floating in working copy on N, as expect it will not compile/link with standard NuWa with GDML switched OFF.:

[blyth@belle7 Components]$ st
A  +    GiGaRunActionGDML.cpp
A  +    GiGaRunActionGDML.h
[blyth@belle7 Components]$ pwd
/data1/env/local/dyb/NuWa-trunk/lhcb/Sim/GaussTools/src/Components

Rejig the code so it will compile and do nothing when HAVE_G4DAE and HAVE_G4GDML are not set.

The headers and lib are present on C (I dont recall tampering there, but it seems I must have):

[blyth@cms01 include]$ l G4GDML*

How to preprocessor protect entire classes with NuWa/cmt ?¶

It would be good to avoid branching just for a few extra classes, if can avoid interference.

Example of private test code NuWa-trunk/dybgaudi/RootIO/RootIOSvc/cmt/requirements:

28 # Below is for test code
29
30 private
31
32 pattern  public_include include_dirs ${<package>_cmtpath}/include
33 pattern private_include include_dirs ../include
34 pattern test_application \
35         public ; \
36         apply_pattern executable_path ; \
37         private ; \
38         apply_pattern public_include ; \
39         application <name> -group=test <files>
40
41
42
43 use CLHEP v* LCG_Interfaces         # in lcgcmt
44 use CLHEPRflx v* Dictionaries           # in relax
45
46 macro_append ROOT_linkopts " -lCLHEPRflx -lCintex "
47 test_application name=RootIOTest files=../test-bin/RootIOTest.cc
48 macro_append RootIOTestlinkopts " -L$(RootIODir) -lRootIO "
49

Example pre-processor setting NuWa-trunk/dybgaudi/DaqFormat/RawRecordPool/cmt/requirements:

1 package RawRecordPool
2
3 use DybPolicy
4
5 library RawRecordPool  *.cc
6
7 macro_append RawRecordPool_cppflags " -DRPC_ERROR_DEBUG=10 "
8
9 apply_pattern install_more_includes more=RawRecordPool

Annoying physvol name truncation + uniqing ¶

physvol names are trucated to 99 chars
names are sometimes but not always uniqued by appending pointer address

30017       <physvol name="/dd/Geometry/Pool/lvNearPoolOWS#pvNearUnistruts#pvNearHalfUnistruts:2#pvNearQuadCornerUnistrus:1#pv">
