2. AIDA and CLHEP
3. The Standard Template Library (STL)
4. Compiler Specific Problems
5. Known Run-Time Problems
6. Compilation Warnings
7. Known Run-Time Warnings
8. Features at Run-Time
9. Items for migration of user code
1. Supported and Tested Platforms
---------------------------------
o SUN Solaris 5.8, C++ 5.4 Patch 111715-02.
o Linux, gcc 2.95.2, gcc 3.2.
This configuration was tested with the RedHat 7.3 distribution,
versions of Geant4 have also been compiled successfully on other
Linux distributions, like Debian or Suse.
The default RedHat compiler gcc-2.96 ditributed in RedHat 7.X is NOT
supported. It has been verified that it produces incorrect binaries,
therefore is not reliable. See also note below.
o Windows-2000/XP and CygWin Tools with: Visual C++ 6.0 Service Pack 5
Platforms configured but not tested and not supported:
o DEC V4.0, cxx C++ V6.1-027
o HP 10.20, aCC C++ B3910B A.01.23
o SGI V6.5.5, CC 7.2.1
o AIX 4.3.2, xlC 6.0
o MacOS 10.2, gcc 2.95.2 / gcc-3.2
2. AIDA and CLHEP
-----------------
Geant4 5.1 requires the installation of CLHEP
(href="http://cern.ch/clhep/INSTALLATION/clhep.html).
Tests have been performed with CLHEP 1.8.0.0.
Geant4 5.1 examples with histogramming cowork with AIDA 3.0 implementations.
These include:
- ANAPHE and components included therein
(see: ANAPHE - http://cern.ch/anaphe)
- JAS (Java Analysis Studio)
(see: JAS - http://jas.freehep.org)
- Open Scientist
(see: Open Scientist - http://www.lal.in2p3.fr/OpenScientist)
AIDA headers can be downloaded from:
http://aida.freehep.org
3. The Standard Template Library
--------------------------------
Native versions of STL have been tested on the following platforms:
Windows/2000, Linux, and SUN.
NOTES:
- Platform specific setup:
o SUN: Native STL is required for ISO/ANSI setup.
o Linux: Native STL is required (non ISO/ANSI setup for egcs compiler only).
o Windows: Native STL and ISO/ANSI setup required (VC++ 6.0).
4. Compiler Specific Problems
-----------------------------
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. Features at Run-Time
-----------------------
o In this release, the implementation of the G4RunManager has been
substantially modified. The calculation of the physics cross-section
tables takes place -after- the "BeamOn" command is issued. Thus, the
initialisation of the run-manager (either through the initialize()
method or the UI command "run/initialize") is noticeably faster
compared to the previous version. On the other hand, more time is
required to get the event loop starting, once issued the "BeamOn"
command.
o Production thresholds are now adopted only for gammas, electrons and
positrons. Other particles do not use the concept of production threshold;
setting cut values for particles rather than the cited three will have no
effect in the application, but will result in a warning message.
9. Items for migration of user code
-----------------------------------
o User applications having user-defined production cuts will work with
no required transition to the new interface, as long as regions are
not used. The new interface for setting production cuts will be
required for using the 'cuts-by-region' feature (see the User's
Guide for Application Developers).
The old interface for setting/controlling production cuts (methods
and UI commands) will be made obsolete in the next public release and
later-on removed.
An example showing the utilisation of the 'cut-by-region' technique is
available in examples/novice/N07.
o The file format of storing physics tables has been changed. Thus all
the stored physics tables must be rebuilt.
o Advanced applications making use of a sub-classed run-manager will have
to migrate to the new initialization scheme and interface defined in
G4RunManager. Particularly, users must be aware of the change in the
sequence of building the physics tables. G4RunManager::BuildPhysicsTable()
must be invoked from G4RunManager::RunInitialization().
G4VUserPhysicsList::SetCuts() does not trigger the construction of the
physics tables, it is just aimed to set the production thresholds (cuts).
All other user mandatory initialization classes are kept as before.
o Applications making use of the prototype STD EM processes and messenger
will have to migrate according to the design iteration implemented in
this new release, examples showing the usage of these processes can be
found in examples/extended/electromagnetic: TestEm2, TestEm3.
o The new data sets for low-energy EM processes G4EMLOW2.1 is required
for applications making use of such processes.
