Problem 1726

in order to get started with using g4py, I try to follow the instructions given here:
https://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ForApplicationDeveloper/html/apas07.html
...but it fails. Seems to be something wrong with "boost"...
This is what I do:

source /afs/cern.ch/sw/lcg/external/geant4/10.0.p03/x86_64-slc6-gcc47-opt/bin/geant4.csh

cd /afs/cern.ch/sw/lcg/external/geant4/10.0.p03/share/environments/g4py

./configure linux64 --with-g4install-dir=/afs/cern.ch/sw/lcg/external/geant4/10.0.p03/x86_64-slc6-gcc47-opt/

boost version >= 1.32.00 is required.

Thanks for helping.

Hello Massi,

This is a hopefully small documentation bug. Obviously, you cannot write into the Geant4 installation on afs. So please copy g4py to a local directory, and then re-run:
cd (some local directory)
cp -R /afs/cern.ch/sw/lcg/external/geant4/10.0.p03/share/environments/g4py g4py
cd g4py

and then re-run

OK, now goes further down, but problem with xercesc... see below.
Where is it ?

thanks Massi

            /usr/include/xercesc does not exist.
            Try --with-xercesc-incdir option.

Please try the following, this got me past th econfigure step, but fails in compilation:
./configure linux64 --with-g4install-dir=/afs/cern.ch/sw/lcg/external/geant4/10.0.p03/x86_64-slc6-gcc47-opt/ --with-xercesc-incdir=/afs/cern.ch/sw/lcg/external/XercesC/3.1.1p2/x86_64-slc6-gcc47-opt/include --with-xercesc-libdir=/afs/cern.ch/sw/lcg/external/XercesC/3.1.1p2/x86_64-slc6-gcc47-opt/lib/

Dear Gunter
yes, indeed, I tried and I passed the configure. Then, both make and make install generate about 10'000 error messages.
(so many that I decided not to post them here...). Is g4py still supposed to work after that ?
