o SUN Solaris 5.7, C++ 5.2 Patch 109508-03.
o Linux, gcc 2.95.2, egcs-2.91.66 (egcs 1.1.2).
This configuration was tested with the RedHat 6.1 distribution, but
versions of Geant4 have also been compiled successfully on more recent
RedHat, Debian and Suse distributions.
o NT 4.0 (Service Pack 4) or Windows-2000 and Cygnus Tools b20 with:
Visual C++ 6.0 Service Pack 5
Platforms also tested but giving rise to some problems - see below:
o DEC V4.0, cxx C++ V6.1-027.
Platforms configured but not tested and not supported:
o HP 10.20, aCC C++ B3910B A.01.23
o SGI V6.5.5, CC 7.2.1 with ObjectSpace
o AIX 4.3.2, xlC compiler with ObjectSpace
2. ANAPHE and CLHEP
-------------------
Geant4 4.0 requires the installation of CLHEP.
See <A href="http://wwwinfo.cern.ch/asd/lhc++/INSTALLATION/clhep.html">
CLHEP</A>. Tests have been performed with CLHEP 1.7.0.0.
By default, the CLHEP installation scripts will activate ISO/ANSI C++ features
if the compiler is capable. You need to explicitly disable CLHEP settings in
case you wish non-ISO/ANSI setup on specific compilers.
Geant4 4.0 coworks with ANAPHE 3.6.5 and components included therein:
Objectivity 6.1.3
HepODBMS 0.3.3.1
CLHEP 1.7.0.0
For more information about ANAPHE 3.6.5, see:
<A href="http://cern.ch/anaphe">ANAPHE</A>
3. The Standard Template Library
--------------------------------
Native versions of STL have been tested on the following platforms:
Windows/2000, Linux, DEC and SUN.
NOTES:
- Platform specific setup:
o DEC: Native STL is required for ISO/ANSI setup.
o SUN: Native STL is required for ISO/ANSI setup (CC 5.2 only).
o Linux: Native STL is required (non ISO/ANSI setup for egcs compiler only).
o W2000: Native STL and ISO/ANSI setup required (VC++ 6.0).
4. Persistency
--------------
Platform
--------
Persistency in Geant4 4.0 release is tested on the following
platforms:
G4SYSTEM OS C++ compiler HepODBMS Objectivity
--------- ----------- ------------ --------- -----------
SUN-CC SunOS 5.7 CC 5.2 0.3.3.1 6.1.3 (*)
Linux-g++ RedHat 6.1 gcc-2.95.2 0.3.3.1 6.1.3 (#)
(*) HepODBMS header files must be prepared with "ooddlx -noline"
option. See below.
(#) See g4odbms_setup[.sh.csh] in example PersistentEx01 in
'geant4/examples/extended/persistency' for example setup scripts.
Known Problems
--------------
- There are several warning messages on some platforms during the
installation of the libraries and the compilation of the examples.
Most of them can be safely ignored. It is annoying but hard to get
rid of them due to various reasons.
- If you are using Solaris7 CC compiler 5.2 (SUN-CC) with the original
release version, persistent header files has to be generated by
ooddlx with "-noline" option due to a bug in C++ compiler.
This workaround applies not only to Geant4 Persistency category but
also to HepODBMS, and the user defined ddl files as well.
This is the default for SUN-CC configuration for Geant4 GNUmakefiles.
When this option is turned on, it removes the "#line" directive of
the file name and the line number of the original .ddl file. As a
consequences, C++ compiler no longer "tells" the correct file name
and the line number of the .ddl file if compiler error occurs. When
you design a persistent object with Geant4 GNUmakefiles and get the
compiler errors, try to identify the problem by first looking into
the header file generated by ooddlx, and then locate the source of
the problem by looking into the .ddl file.
A patch to the compiler is released from SUN, and you may remove this
option by commenting out the line:
G4DDLX_FLAGS += -noline
in the file $G4INSTALL/config/sys/SUN-CC.gmk.
You can check the SUN-CC patch by the following command:
% what `which CC` | grep RELEASE
5. Compiler Specific Problems
-----------------------------
o DEC V4.0, cxx C++ V6.1-027.
- We have found cases of mis-compilation of min and max templates
on DEC. We have traced those which cause serious malfunction
but there is no guarantee that there are no other cases.
Detailed inspection of assembler output suggests that this
problem might not be confined to min and max. This has been
reported to DEC/Compaq. We understand a new version 6.2 of the
compiler is now available. However we cannot guarantee correct
execution of Geant4 on DEC with the current version of the
compiler.
- A bug in cin.getline() system function causes an anomalous
behavior when running in interactive-mode on DEC-cxx 6.1 in
ISO/ANSI mode. We tested the bug has been fixed in more recent
versions of the compiler.
6. 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
7. 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.
8. 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.
