Hi, Just install the libxml2 library and its headers, recompile Gate and it will be ok, finally !

After the geant4 installation, I can find the env.sh script file in two paths in my system. /home/gary/GATE4.0/geant4.9.1.p03/.config/bin/Linux-g++ /home/gary/GATE4.0/geant4.9.1.p03/install/src/geant4/.config/bin/Linux-g++ when I type gary@polyu-gary:~/GATE4.0/geant4.9.1.p03$ source /home/gary/GATE4.0/geant4.9.1.p03/.config/bin/Linux-g++ or gary@polyu-gary:~/GATE4.0/geant4.9.1.p03$ source /home/gary/GATE4.0/geant4.9.1.p03/install/src/geant4/.config/bin/Linux-g++/env.sh I can get the following information: On this machine the G4SYSTEM=Linux-g++ On this machine the G4INSTALL=/home/gary/GATE4.0/geant4.9.1.p03/install/src/geant4 On this machine the G4LIB=/home/gary/GATE4.0/geant4.9.1.p03/install/lib/geant4 On this machine the G4LEVELGAMMADATA=/home/gary/GATE4.0/geant4.9.1.p03/data/PhotonEvaporation2.0 On this machine the G4RADIOACTIVEDATA=/home/gary/GATE4.0/geant4.9.1.p03/data/RadioactiveDecay3.2 On this machine the G4LEDATA=/home/gary/GATE4.0/geant4.9.1.p03/data/G4EMLOW5.1 On this machine the G4NEUTRONHPDATA=/home/gary/GATE4.0/geant4.9.1.p03/data/G4NDL3.12 On this machine the G4ABLADATA=/home/gary/GATE4.0/geant4.9.1.p03/data/G4ABLA3.0 On this machine the CLHEP_BASE_DIR=/home/gary/GATE4.0/CLHEP/install On this machine the CLHEP_INCLUDE_DIR=/home/gary/GATE4.0/CLHEP/install/include On this machine the CLHEP_LIB_DIR=/home/gary/GATE4.0/CLHEP/install/lib On this machine the CLHEP_LIB=CLHEP On this machine the G4VIS_BUILD_RAYTRACERX_DRIVER=1 On this machine the G4VIS_USE_RAYTRACERX=1 On this machine the XMFLAGS= On this machine the XMLIBS= On this machine the XMFLAGS= On this machine the XAWFLAGS= On this machine the XAWLIBS= On this machine the G4LIB_BUILD_SHARED=1 On this machine the G4LIB_USE_GRANULAR=1 On this machine the G4UI_USE_TCSH=1 LD_LIBRARY_PATH is set to include CLHEP and Geant4 libraries.

But for my gate4 installation, I follow the guide, gary@polyu-gary:~/GATE4.0/gate_v4.0.0$ exprot G4VERSION=9.1 then copy geant env.sh file into path G4INSTALL=/home/gary/GATE4.0/geant4.9.1.p03/install/src/geant4, then type gary@polyu-gary:~/GATE4.0/gate_v4.0.0$ source env_gate.sh I can get: G4WORKDIR set to .
