Hello, I hope you can help me. The following is the error message for trying to compile example N04. I've encountered the same error when trying to compile my own application. mjmchugh:~$ pwd /home/mjmchugh/Geant4/geant4.9.5.p01/examples/novice/N04 mjmchugh:~$ make Making dependency for file exampleN04.cc ... /home/mjmchugh/Geant4/geant4.9.5.p01/source/interfaces/basic/include/G4UIQt.hh:40:21: fatal error: qobject.h: No such file or directory compilation terminated.

I just upgraded to Ubuntu 12.10 and when I attempted to compile applications that had previously been working similar errors occurred. Best, Marty
Could you rebuild with make CPPVERBOSE=1 and report the output here please? We need to see what include paths and links are being used. Could you also confirm the location of the QtCore, QtGui and QtOpenGL libraries please?
My OS is Ubuntu. I try to fix the problem by setting the below environment variables. export QTMOC="/usr/bin/moc-qt4" export QTFLAGS="-I/usr/include/qt4 -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtOpenGL" export QTLIBS="-L/usr/lib -lQtCore -lQtGui" export GLQTLIBS="-L/usr/lib -lQtCore -lQtGui -lQtOpenGL"
Release 10.0 will include a fix to export environment variables needed by Geant4Make to locate non-standard installs of Qt. Note however that Geant4Make is deprecated.
