0060 This configuration was tested with the RedHat 7.3 distribution,
0061 versions of Geant4 have also been compiled successfully on other
0062 Linux distributions, like Debian, Suse or more recent RedHat systems.
0063 The default RedHat compiler gcc-2.96 distributed in RedHat 7.X is NOT
0064 supported. It has been verified that it produces incorrect binaries,
0065 therefore is not reliable. See also <A HREF="#note-1">note below</A>.</LI>

0126 <LI><A NAME="note-1"><B>Linux Red Hat 7.X, gcc-2.96</B></A>.
0127 <UL>
0128 <LI>The default compiler distributed by Red Hat since release 7.0 is
0129 NOT supported and not considered reliable for running a Geant4-based
0130 application. In more than one test case, binaries produced by gcc-2.96
0131 have shown incorrect behavior, either due to wrong order of
0132 initialisation of static data in memory or to bugs in the system
0133 <TT>iostream</TT> classes, problems which apparently have all been
0134 solved in more recent versions of the compiler (3.X series).<BR>
0135 For information, gcc-2.96 is a compiler that has never been
0136 officially released, nor supported by the GNU team itself and is not
0137 considered reliable by the authors (for more information, see also

0192 <H2>7. Major items for migration of user code</H2>
0193
0194 There're not known migrations necessary if upgrading from release 6.1,
0195 other than recompilation and/or reinstallation of libraries and user
0196 applications.
0197 <P> </P>
0198 <B>Future migration for <TT>G4VParticleChange</TT> class</B>
0199 <P> </P>
0200 For the future releases, an interface change to the class
0201 <TT>G4VParticleChange</TT> is foreseen. The required changes are already
0202 implemented in this release while still keeping valid the old interface.<BR>
0203 The following methods will be removed in the future:
0204 <PRE>
0205 void SetTrueStepLength(G4double truePathLength);
0206 void SetLocalEnergyDeposit(G4double anEnergyPart);
0207 G4TrackStatus GetStatusChange() const;
0208 void SetStatusChange(G4TrackStatus status);
0209 void SetSteppingControl(G4SteppingControl StepControlFlag);
0210 void SetParentWeight(G4double);
0211 </PRE>
0212 They will have to be replaced by the following methods, respectively:
0213 <PRE>
0214 void ProposeTrueStepLength(G4double truePathLength);
0215 void ProposeLocalEnergyDeposit(G4double anEnergyPart);
0216 G4TrackStatus GetTrackStatus() const;
0217 void ProposeTrackStatus(G4TrackStatus status);
0218 void ProposeSteppingControl(G4SteppingControl StepControlFlag);
0219 void ProposeParentWeight(G4double);
0220 </PRE>
0221 <P> </P>
0222 <B>Future migration for <TT>G4GeneralParticleSource</TT> class</B>
0223 <P> </P>
0224 A 'tree-structured' command format is implemented in this release for
0225 <TT>G4GeneralParticleSource</TT>. The old UI commands have been kept
0226 for backward compatibility but will be removed in the future.<BR>

0373 transformations (true length to geometrical length and back) have

0376 scattering of low energy particles. It will affect the resolution
