Description schiefer 2001-11-10 06:22:55 CET 
When I run Configure -install and set all necesary parameters appropriatly, I
get several compile time errors, starting at G4PhysicsFreeVeector.cc:

Compiling G4PhysicsFreeVector.cc ...

Error 1

I cannot figure out what casues the problem and if I somwhow configured wrongly
or if it indeed is a bug.

I am using RedHat Linux 7.0, g++ 2.96

Thank you for your support,

Comment 1 Gabriele Cosmo 2001-11-10 11:02:59 CET 
Geant4 3.2 is not supported on gcc-2.96.XX.
Moreover, it is known that Red-Hat 7.0 is shipped with a flawed and
unofficial version of the gcc compiler, -never- released by GNU.
This compiler may require strict ISO/ANSI setup; if so, the following
may help, although we cannot guarantee...
In geant4/config/sys/Linux-g++.gmk modify the line:

  CXXFLAGS  := -pipe -fno-for-scope -DGNU_GCC

to

  CXXFLAGS  := -ansi -pedantic -pipe -fno-for-scope -DGNU_GCC

And the following lines:

  ifdef G4USE_OSPACE
    CPPFLAGS += -DOS_LINUX_2 -DOS_NEW_CHECK -DOS_STL_ASSERT
    CPPFLAGS += -DOS_NO_WSTRING -DOS_NO_ALLOCATORS
    CPPFLAGS += -I$(OSPACE_BASE_DIR)/ospace/std -I$(OSPACE_BASE_DIR)
#  else
#    G4USE_STD_NAMESPACE := yes
#    CPPFLAGS += -DG4USE_STD_NAMESPACE
  endif

to:

  G4USE_STD_NAMESPACE := yes
  CPPFLAGS += -DG4USE_STD_NAMESPACE

Rebuild from scratch:

  cd geant4/source
  gmake clean
  gmake

Regards.

Thanks, I installed gcc 2.95.3 and it seems to work fine.
