0075 Notes:
0076
0077 o Geant4 1.1 is based on STL and the code has been upgraded to be
0078 ISO-ANSI C++ compliant. Code in this release include the ability to
0079 choose between using the 'std' namespace in ISO/ANSI mode or using
0080 traditional style programming in the global namespace (exceptions
0081 still apply concerning mathematical functions - <math.h> in global
0082 namespace is still in use, or standard C I/O functions).
0083
0084 The source code and some binary libraries are available through our "Source
0085 Code" Web page:
0086 - see our Geant4 Home Page (http://cern.ch/geant4).
0087
0088 Please refer to the Geant4 User Documentation
0089 (http://cern.ch/geant4/G4UsersDocuments/Overview/html)

0105
0106 1. Supported and Tested Platforms
0107 ---------------------------------
0108
0109 o SUN Solaris 5.6, C++ 4.2 patch 104631-04
0110 o HP 10.20, aCC C++ B3910B A.01.18 or A.01.21
0111 o Linux 2.2.5-22, gcc C++ egcs-2.91.66 (egcs 1.1.2).
0112 This configuration was tested in the RedHat 6.1 distribution, but
0113 versions of Geant4 have also been compiled successfully on, Debian
0114 and Suse distributions.
0115
0116 Platforms/compilers also tested but giving rise to some problems - see below:
0117
0118 o DEC V4.0, cxx C++ V6.1-027.
0119 o SUN Solaris 5.6, C++ 5.0 patches 107357-07, 107311-09
0120 o NT 4.0 with Service Pack 4 and Cygnus Tools b20 with:
0121 Visual C++ 6.0 Service Pack 2
0122
0123 Platforms configured but not tested and not supported:
0124 o SGI V6.5.5, CC 7.2.1 with ObjectSpace
0125 o AIX 4.3.2, xlC compiler with ObjectSpace
0126
0127 2. CLHEP 1.4
0128 ------------
0129
0130 Geant4 1.0 requires the installation of CLHEP 1.4.
0131
0132 See CLHEP 1.4 (http://cern.ch/clhep/INSTALLATION/clhep.html).
0133
0134 Be aware, for the platforms listed below, the standard CLHEP installation
0135 will use ISO-ANSI setup:
0136
0137 DEC: if using the compiler option "-std strict_ansi", it is required to
0138 compile Geant4 in ISO-ANSI mode and 'native' STL.
0139
0140 NT: if CLHEP has been installed with the line:
0141 #define HEP-USE-STD 1
0142 uncommented in file config/CLHEP-x86-cygnus-win32, it is required to
0143 compile Geant4 in ISO-ANSI mode and 'native' STL.
0144
0145
0146
0147 3. The Standard Template Library
0148 --------------------------------
0149
0150 The following versions of STL have been tested:
0151
0152 "Native" STL on: Linux, HP, DEC, SUN, NT.
0153
0154 ObjectSpace STL on
0155 DEC, HP, NT and SUN.
0156
0157 See ObjectSpace (http://www.objectspace.com).
0158
0159 This is selected at installation/compile time by the environment variable
0160 G4USE_OSPACE in the case of the latter - see documentation.
0161
0162 NOTES:
0163 - Be aware that by default, the installation scripts will expect to use
0164 the native STL implementation. You must set the G4USE_OSPACE variable
0165 in the environment in order to select the ObjectSpace implementation.
0166
0167 - Platforms specific setup:
0168 o DEC: - Default: 'native' STL and ISO-ANSI setup.
0169 - G4USE_OSPACE set: selects ObjectSpace STL (required)
0170 and no ISO-ANSI setup.
0171 o HP: - Default: 'native' STL and ISO-ANSI setup.
0172 - G4USE_OSPACE set: selects ObjectSpace STL (required)
0173 and no ISO-ANSI setup.
0174 - G4NO_STD_NAMESPACE set: either ObjectSpace or 'native' STL
0175 can be used.
0176 o SUN: - Default: 'native' STL and ISO-ANSI setup.
0177 This setup requires the CC compiler version 5.0.
0178 - G4USE_OSPACE set: selects ObjectSpace STL (required)
0179 and no ISO-ANSI setup.
0180 o Linux: native STL is required. No ISO-ANSI setup.
0181 o NT: - Default: 'native' STL and ISO-ANSI setup.
0182 - G4USE_OSPACE set: selects ObjectSpace STL (required)
0183 and no ISO-ANSI setup.
0184
0185 Geant4 1.1 requires the Standard Template Library.
0186 In the interest of stability, a significant part of the code still makes use
0187 of the "STL Interface" wrapper classes. For these the emphasis has remained
0188 on correct behaviour, rather than performance.
0189
0190
0191 4. Persistency
0192 --------------
0193
0194 - See release notes for Geant4 1.0.
0195
0196
0197 5. Compiler Specific Problems
0198 -----------------------------
0199
0200 o DEC V4.0, cxx C++ V6.1-027.
0201
0202 We have found cases of mis-compilation of min and max templates
0203 on DEC. We have traced those which cause serious malfunction
0204 but there is no guarantee that there are no other cases.
0205 Detailed inspection of assembler output suggests that this
0206 problem might not be confined to min and max. This has been
0207 reported to DEC/Compaq. We understand a new version 6.2 of the
0208 compiler is now available. However we cannot guarantee correct
0209 execution of Geant4 on DEC with the current version of the
0210 compiler.
0211
0212 o SUN Solaris 5.6, CC 5.0 patches 107357-07, 107311-09
0213
0214 The listed patches are required in order to fix a bug in the
0215 system Standard I/O libraries for streams.
0216 Part of the Geant4 code can be compiled only in debug mode (G4DEBUG
0217 set). A bug in the compiler optimiser causes the compiler to run in
0218 an infinite loop during compilation. Also, the inclusion of debug
0219 symbols causes the generation of abnormally huge binary objects.
0220 A bug report is being filed to SUN Support.
0221
0222 o NT
0223
0224 - Due to limitations of the VC++ optimiser, testing was done using
0225 the debuggable version only.
0226 - g3tog4 has not been ported to NT.
0227 - During the making of dependency files during compilation there
0228 are repeated warnings ("Strstrea.h not found") - this is an
0229 artifact of using g++ for this purpose.
0230 - Ignore linker warnings: "conflicts with use of other libs".
0231 - Ignore linker errors: "unresolved external symbol
0232 __imp__MessageBoxA@16".
0233
0234 6. Known Run-Time Problems
0235 --------------------------
0236
0237 o Reading STEP files on DEC with optimised libraries causes a Memory
0238 fault - but see notes on DEC above.
0239 o In rare cases heavy ions appear not to be properly stopped and killed
0240 in tracking, therefore Geant4 sticks making many small steps. This
0241 behaviour has been observed on SUN and is under investigation.
0242 o On WindowsNT and DEC (ISO-ANSI setup), a problem can occur reading the data
0243 files associated with the environment variable $NeutronHPCrossSections.
0244 The problem is being investigated.
0245
0246
0247 7. Compilation Warnings
0248 -----------------------
0249
0250 There are compilation warnings on some platforms. We do not believe
0251 that any will lead to incorrect run-time behaviour, however a parallel
0252 Q/A activity is on going to reduce them.
0253
0254
0255 8. Known Run-Time Warnings
0256 --------------------------
0257
0258 The following messages can be written to error output while tracking. We
0259 believe none give rise to incorrect behaviour.
0260
0261 o G4PropagatorInField::LocateIntersectionPoint: Warning: Integration
0262 inaccuracy requires an adjustment in the step's endpoint Two
0263 mid-points are further apart than their curve length difference:
0264 Dist = xxx curve length = yyy
0265 o Warning in G4Navigator::ComputeStep: The Step's starting point has
0266 moved...
0267 o G4PropagateInField: Warning: Particle is looping
0268 - tracking in field will be stopped.
0269 It has performed 10000 steps in Field while a maximum of 10000
0270 are allowed.
0271
0272 For very high energy muons (ex. 1 TeV) warnings of this kind might be
0273 generated:
0274
0275 o G4ParticleChange::CheckIt : the Momentum Change is not unit vector !!
0276 Difference: 1e-09
0277 G4ParticleChange::CheckIt
