#       GEANT 4 - Architecture configuration script for GNU Make
#
#       First implementation: July 7th 1995
#
# Description
# -----------
# to override variables defined in this script, use "gmake -e", this will
# cause environment variables to take precedence. In this case watch for
# inadvertant overrides!
#
# List of the supported architectures/compilers and related flavors for
# the environment variable G4SYSTEM:
#
#          Linux-g++   Linux (Red Hat Enterprise/SCL5), gcc-4.1.2 (default)
#
#          Darwin-g++  MacOSX 10.6, gcc-4.2.1
#
#          WIN32-VC    Windows/XP and Microsoft Visual C++ 9.0
#                      Adding CYGWIN32 tools

# The user can define his own values of OGLFLAGS and OGLLIBS.
# OGLFLAGS gives the directory containing include files.

# to specify the path in OGLFLAGS, since added already by default by the
# compiler.  OGLHOME can also point to a special installation.
# If the user does not set his/her own values, system-dependent values
# are set below.  Most system-dependent code assumes OGLHOME is set.
