---+ Building DD4hep on a linux box with ILCSoft already installed

%TOC%

---++ Ingredients

   1. CMake
   1. Xerces-C
   1. expat-devel
   1. Geant4
   1. DD4hep

---++ Problems

   1. Need CMake 2.8 or newer
   1. Geant4 must be compiled with *GDML* and needs *expat-devel*
   1. Downloaded root binary needs libpcre.dylib
   1. 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
   1. unpack
   1. cd cmake-2.8.12.2/
   1. ./bootstrap --prefix=~/Utils4DD4hep/packages/cmake
   1. make
   1. make install
   1. export PATH=~/Utils4DD4hep/packages/cmake/bin:$PATH

Xerces-C:

   1. get Xerces-C from http://xerces.apache.org/xerces-c
   1. unpack 
   1. cd  xerces-c-3.1.1/
   1. set ac_default_prefix=~/Utils4DD4hep/packages/xercesc in the configure script
   1. ./configure
   1. make
   1. 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
   1. unpack
   1. cd geant4.9.5.p02/
   1. mkdir build 
   1. cd build
   1. 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 ..
   1. make 
   1. make install

DD4hep itself:

   1. get DD4hep from https://svnsrv.desy.de/viewvc/aidasoft/DD4hep/?view=tar 
   1. cd DD4hep
   1. edit DDG4/src/Geant4UIManager.cpp and change line 55 to ui = new !G4UIExecutive(1,(char**)args);//,m_sessionType.c_str());
   1. mkdir build
   1. cd build/
   1. source /data/ppe01/sl5x/x86_64/root/5.34.07/bin/thisroot.sh
   1. source ~/Utils4DD4hep/packages/Geant4/bin/geant4.sh
   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/
   1. make -j install fails because of coding errors in DDRec/src/Surface.cpp
