Geant4 5.0 Release Notes
------------------------
13th December 2002
These are the main new features/fixes included in this release since the
last public release (for the detailed list of fixes/additions, please refer
to the related History files):
o Configuration:
-------------
- Specific setups:
o Linux-g++.gmk: added assignment 'CC := gcc' for default 'cc' compiler.
o SUN-CC.gmk: removed -L/usr/lib path specification from LOADLIBS
definition.
o AIX-xlC.gmk: updated for porting on AIX with xlC 6.0 (unsupported).
o WIN32-g++.gmk: updated setup to compile with -ansi and gcc-2.95.3
for most recent versions of CygWin (unsupported).
o Darwin-g++.gmk: updated setup to support MacOS 10.2 (unsupported).
- liblist.c:
o Enhanced script to provide the whole list of installed libraries
in the correct order, without requiring parsing of dependencies.
The functionality is achieved by invoking "liblist" with option '-m",
i.e. - liblist -m [libpath] < libname.map
where [libpath] is the path where libraries are placed
(i.e. $G4LIB/$G4SYSTEM).
- binmake.gmk:
o Use "liblist -m [libpath]" to retrieve the list of libraries to link
in case headers are installed in $G4INCLUDE, and granular libraries
are used.
- Adopt new dependency file algorithm to avoid leaving corrupt .d files
when #include's cannot be found.
- Removed ODBMS setup. Now library for persistency is built as part of the
kernel and specific implementations for persistency have been moved to
examples. Setup for ODBMS no more required. G4USE_HEPODBMS is no longer
used.
- Removed obsolete setup for ObjectSpace-STL (G4USE_OSPACE and related
variables). Removed obsolete variable G4USE_STL.

-----------------------------
o Linux Red Hat 7.X, gcc-2.96.
- The default compiler distributed by Red Hat since release 7.0 is
NOT supported and not considered reliable for running a Geant4-based
application. In more than one test case, binaries produced by gcc-2.96
have shown incorrect behavior, either due to wrong order of
initialisation of static data in memory or to bugs in the system
iostream classes, problems which apparently have all been solved in
more recent versions of the compiler (3.X series).
For information, gcc-2.96 is a compiler that has never been
officially released, nor supported by the GNU team itself and is not
considered reliable by the authors (for more information, see also
http://gcc.gnu.org/gcc-2.96.html).
5. Known Run-Time Problems and Limitations
------------------------------------------
For a complete list of outstanding run-time problems and to submit any
problem you may find running this version of Geant4, please refer to the
Geant4 Problem Reporting System, available on the Web at this address:
http://wwwinfo.cern.ch/asd/cgi-bin/geant4/problemreport
6. Compilation Warnings
-----------------------
There are compilation warnings on some platforms. We do not believe
that any will lead to incorrect run-time behaviour, but we are working
on reducing them.
7. Known Run-Time Warnings
--------------------------
The following messages can be written to error output while tracking.
We believe none give rise to incorrect behaviour.
o G4PropagateInField: Warning: Particle is looping
- tracking in field will be stopped.
It has performed 10000 steps in Field while a maximum of 10000
are allowed.
8. Items for migration of user code
-----------------------------------
o Compilation/installation of the 'g3tog4' module is now -optional- in
release 5.0 and can be triggered only if G4USE_G3TOG4 is set during
installation.
o The new data sets for photon-evaporation and radioactive-decay are
required, old data-sets are not compatible with this release.
o Definition of the state IDs in G4ApplicationState have changed to
prepend the "G4State_" prefix to the original state ID (i.e. "Idle"
becomes "G4State_Idle", "Init" becomes "G4State_Init", and so on...).
The user code (particularly, user defined messengers defining state
dependent commands) will need to migrate to this new convention.
o The interface for usage of the scintillation process has changed.
Refer to the user's manual to learn about how to migrate the user code
to use the new interface.
o Interfaces for importance biasing and scoring have substantially changed
and migration of the user code using these classes is required. Refer to
the user's manual to learn about how to migrate the user code
to use the new interfaces.
o User defined solids will need to implement a new method:
std::ostream& StreamInfo(std::ostream& os) const
to dump solid's contents to an output stream.
The method is now pure virtual in the base class G4VSolid.
o The base class G4VTrajectory has been enhanced and new pure virtual
functions have been introduced in G4VGraphicsScene:
void AddThis(const G4VTrajectory&)
void AddThis(const G4VHit&)
User inherited classes require concrete implementations of the methods
above, as well.
