Description Nicola Mori 2014-07-22 14:42:20 CEST 
Configuring the build of g4py in Geant4 10.00.p02 with CMake leads to a failure due to the lack of inclusion of Xerces-C header folder. I configure with:

$ cmake -DXERCESC_ROOT_DIR=/wizard/04/mori/software/install/XERCESC_3.1.1/ -DBOOST_ROOT=/wizard/04/mori/software/install/BOOST_1.55.0/ -DPYTHON_LIBRARY=/wizard/04/mori/software/install/PYTHON_2.7.8/lib/ -DPYTHON_INCLUDE_DIR=/wizard/04/mori/software/install/PYTHON_2.7.8/include/python2.7/ ../

Then, building the target pyG4gdml gives this error:

compilation terminated.


It seems that the proper -I flag for Xerces-C headers folder is missing, even if during configuration no error/warning has come out. If I add the flag:

  -I/wizard/04/mori/software/install/XERCESC_3.1.1/include

the file is compiled without errors.
Comment 1 Koichi Murakami 2015-12-11 06:36:32 CET 
Fixed in the 10.1 release.

Add the following line  in CMakeLists.txt in source/gdml/

include_directories (${XERCESC_INCLUDE_DIRS})
