Description jakob.himmelman 2001-02-28 01:43:42 CET 
I have RedHat 7.0 full install right from the CD. CLHEP compiled just fine.
After setting the needed environmental variables in /etc/profile I tried to
install geant 4.3.0. The system is identified as Linux-g++ but when compiling I
get a number of parse and compile errors like :
-------------snip
src/G4ReactionDynamics.cc:3591:parse error before ':'
src/G4ReactionDynamics.cc:3784:internal error before #122
src/G4ReactionDynamics.cc:3584 compiler error

------------------snip
When I try to compile N01 this is not possible in the absence of libG4process.a
What to do?

Thank You

The Linux distribution we support on Geant4 3.0 is Red-Hat 6.1
with egcs-1.1.2 compiler installed.
We're currently working on porting the code on gcc 2.95.2, but
cannot reproduce the problem reported here.
One observation:
home/.../de_exitation/include/G4solver/template.cc
                                      ^
                                      should be '.'
As for the error in G4ReactionDynamics.cc:3591, try to modify
expressions adding parenthesis; problems of the parser installed
in your system ?

More info... (from a user: rob.pywell@usask.ca)
---------
Thought I would let you know...
The gcc-2.96-54 shipped with Red Hat 7.0 is flawed.
Even the update version gcc-2.96-69 doesn't work for c++.

I installed the last stable version gcc-2.95.3 from the
gcc site and all of GEANT4.3.1 compiles fine on Red Hat 7.0
