# - Script for setting up backward compatibility with GNU make user toolchain
|
|
#
|
|
# The GNU make based buildsystem for Geant4 provides a toolchain for users
|
|
# building simple Geant4 applications. The old style build and install of
|
|
# Geant4 provides a customized set of non-standard install paths with use of
|
|
# the toolchain dependent on environment variables pointing to the install
|
|
# paths.
|
|
#
|
|
# This script processes information on the CMake install paths, system and
|
|
# compiler to determine the following variables for backward compatibility
|
|
#
|
|
# GEANT4_SYSTEM : Old style system name, e.g. 'Linux', 'Darwin' or 'WIN32'
|
|
#
|
|
# GEANT4_COMPILER: Old system compiler id, e.g. 'g++', 'VC'.
|
|
#
|
|
# G4INSTALL : Location of config subdirectory containing GNU make
|
|
# fragment files for toolchain.
|
|
#
|
|
# G4INCLUDE : Old style path to location of Geant4 headers
|
|
#
|
|
# G4LIB : Old style library directory path. Rather than
|
|
# containing the actual libraries, it is expected to
|
|
# contain subdirectories named
|
|
# GEANT4_SYSTEM-GEANT4_COMPILER
|
|
#
|
|
#
|
|
# These variables are used in CMake configuration files which generate shell
|
|
# scripts (C and Bourne flavour) the user can source to set up their
|
|
# environment. These replace the old style 'env.(c)sh' scripts to allow
|
|
# users to work with the new CMake built libraries transparently if
|
|
# their application relies on the old style toolchain.
|
|
#
|
|
# Compatibility with the library path style:
|
|
#
|
|
# <prefix>/lib/G4SYSTEM-G4COMPILER
|
|
#
|
|
# is provided by installing a directory 'geant4-<version>' in the actual
|
|
# library directory and creating a symbolic link inside this directory
|
|
# pointing up one directory level.
