1. for the last compilation, had to edit CMakeLists.txt and insert an add_subdirectory(DDG4) on line 156, and then change in DDG4/include/DDG4/IoStreams.h two things: boost/iostreams/detail/path.hpp to boost/filesystem/path.hpp and boost::iostreams::detail::path to boost::filesystem::path.

1. (source /afs/phas.gla.ac.uk/data/ilc/software/ilcsoft/v01-17/init_ilcsoft.sh)

1. source /afs/phas.gla.ac.uk/data/ilc/software/ilcsoft/v01-17/init_ilcsoft.sh

1. cmake -DBUILD_TESTING=On ..
2. make install

1. better to have a working ILCSoft installation, else, if trying to install from scratch it gets very complicated
2. Root older than 5.34 gives problems at compilation (mismatching function prototypes)

Testing:

[protopop@ppepc102 build]$ make test
Running tests...

100% tests passed, 0 tests failed out of 3

Total Test time (real) =   1.04 sec

First example

1. cd DD4hep
2. source ./bin/thisdd4hep.sh
3. cd examples/firstExample
4. mkdir build; cd build/

1. (comment out unnecessary packages in CMakeLists.txt)

1. ILCSoft installation

1. get DD4hep with 'svn co https://svnsrv.desy.de/public/aidasoft/DD4hep/trunk DD4hep'

1. comment out unnecessary packages in CMakeLists.txt

1. source /afs/phas.gla.ac.uk/data/ilc/software/ilcsoft/v01-14/init_ilcsoft.sh

1. cmake ..

1. source bin/thisdd4hep.sh

1. ./bin/Test_execute ../compact/Sensor_Test.xml

1. cmake -DCMAKE_INSTALL_PREFIX=~/DD4hep -DDD4HEP_WITH_GEANT4=on -DGeant4_DIR=~/Utils4DD4hep/packages/Geant4/lib64/Geant4-9.5.2 -DDD4HEP_USE_XERCESC=ON -DXERCESC_ROOT_DIR=~/Utils4DD4hep/packages/xercesc ../tags/v00-06
2. make -j install

First test

1. source /afs/phas.gla.ac.uk/data/ilc/software/ilcsoft/v01-14/init_ilcsoft.sh
2. cd examples/firstexample
3. mkdir build
4. cmake -DDD4hep_DIR=../../ ../
5. make -j

1. get DD4hep from https://svnsrv.desy.de/viewvc/aidasoft/DD4hep/?view=tar

1. cmake -DCMAKE_INSTALL_PREFIX=~/DD4hep -DDD4HEP_WITH_GEANT4=on -DGeant4_DIR=~/Utils4DD4hep/packages/Geant4/lib64/Geant4-9.5.2 -DDD4HEP_USE_XERCESC=ON -DXERCESC_ROOT_DIR=~/Utils4DD4hep/packages/xercesc ../trunk/
2. make -j install fails because of coding errors in DDRec/src/Surface.cpp

Building DD4hep on a linux box with ILCSoft already installed

Ingredients

1. CMake
2. Xerces-C
3. expat-devel
4. Geant4
5. DD4hep

Problems

1. Need CMake 2.8 or newer
2. Geant4 must be compiled with GDML and needs expat-devel
3. Downloaded root binary needs libpcre.dylib
4. DD4hep needs libssl.1.0.0.dylib

Installation Steps

Would be great if this could have been done simpler, but after a lot of frustrating trial and error I collected this list of must do’s:

CMake:

1. get cmake-2.8.12.2 from http://www.cmake.org
2. unpack
3. cd cmake-2.8.12.2/
4. ./bootstrap --prefix=~/Utils4DD4hep/packages/cmake
5. make
6. make install
7. export PATH=~/Utils4DD4hep/packages/cmake/bin:$PATH

Xerces-C:

1. get Xerces-C from http://xerces.apache.org/xerces-c
2. unpack
3. cd xerces-c-3.1.1/
4. set ac_default_prefix=~/Utils4DD4hep/packages/xercesc in the configure script
5. ./configure
6. make
7. make install

Expat:

1. install expat-devel on the machine via yum

Geant4:

1. get geant4.9.5.p02 source from http://geant4.web.cern.ch/geant4/support/source_archive.shtml
2. unpack
3. cd geant4.9.5.p02/
4. mkdir build
5. cd build
6. cmake -DCMAKE_INSTALL_PREFIX=~/Utils4DD4hep/packages/Geant4 -DGEANT4_USE_GDML=ON -DXERCESC_INCLUDE_DIR=~/Utils4DD4hep/packages/xercesc/include -DXERCESC_LIBRARY=~/Utils4DD4hep/packages/xercesc/lib/libxerces-c.so -DEXPAT_INCLUDE_DIR=/usr/include -DEXPAT_LIBRARY=/lib64/libexpat.so.0 ..
7. make
8. make install

DD4hep itself:

1. get DD4hep with svn co https://svnsrv.desy.de/public/aidasoft/DD4hep/trunk DD4hep
2. cd DD4hep
3. edit DDG4/src/Geant4UIManager.cpp and change line 55 to ui = new G4UIExecutive(1,(char**)args);//,m_sessionType.c_str());
4. mkdir build
5. cd build/
6. source /data/ppe01/sl5x/x86_64/root/5.34.07/bin/thisroot.sh
7. source ~/Utils4DD4hep/packages/Geant4/bin/geant4.sh
8. cmake -DCMAKE_INSTALL_PREFIX=~/DD4hep -DDD4HEP_WITH_GEANT4=on -DGeant4_DIR=~/Utils4DD4hep/packages/Geant4/lib64/Geant4-9.5.2 -DDD4HEP_USE_XERCESC=ON -DXERCESC_ROOT_DIR=~/Utils4DD4hep/packages/xercesc ..
9. make
10. make install
