[Gate-users] Installing Gate v6.2 and Geant4 on OSX 10.8.3, problems with CLHEP

[Jenny Nilsson]

Hello all.
I’ve been trying to install Geant4.9.5.p02 and using external CLHEP on Mac OS X 10.8.3, Mountain Lion. There seems to be some problems with Cmake finding the CLHEP installation.

I’ve installed CLHEP 2.1.1.0, which seems to have worked fine. CLHEP is in directory /Applications/2.1.1.0 and the variable paths are updated

export PATH=$Applications/2.1.1.0/CLHEP/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/Applications/2.1.1.0/CLHEP/lib

When installing Geant4 using ccmake I get the following for CLHEP:

CLHEP_CONFIG_EXECUTABLE    /Applications/2.1.1.0/CLHEP
CLHEP_INCLUDE_DIR          /Applications/2.1.1.0
CLHEP_LIBRARY              /Applications/2.1.1.0/lib

And when configuring I get the following message:

CMake Error at cmake/Modules/FindCLHEP.cmake:179 (file):
   file Internal CMake error when trying to open file:
   /Applications/2.1.1.0/CLHEP/Units/defs.h for reading.
 Call Stack (most recent call first):
   cmake/Modules/Geant4OptionalComponents.cmake:41 (find_package)
   CMakeLists.txt:79 (include)

 CMake Error at /Applications/CMake
 2.8-10.app/Contents/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmak
 e:97 (message):
   Could NOT find CLHEP:

   Incompatible versions, (found) < 2.1.0.1(required)

    (missing:  CLHEP_VERSION_COMPATIBLE) (Required is at least version
 "2.1.0.1")


Any suggestion on what has gone wrong?
Does it matter, with respect to Gate 6.2 if I use Geant4.9.5p01 or Geant4.9.5.p02

Also, the manual mention CLHEP_ROOT_DIR, but I can’t seem to find this when using ccmake. Is this something of concern?
Regards,
Jenny
