# Commands to build GT.M downloaded from SourceForge
# 1. 'cd' to the GT.M directory where sr_* directories are copied to.
# 2. Define an environment variable gtm_curpro to point to the full
#    path of the prior GT.M installation.
#    (download and install GT.M binary distribution from SourceForge
#    if you do not have GT.M installed already).
# 3. To build debug version with no compiler optimzations -
# 	gmake -f sr_unix/comlist.mk -I./sr_unix -I./sr_linux buildtypes=dbg gtm_ver=$PWD
#    To build a version enabling optimizations -
#	gmake -f sr_unix/comlist.mk -I./sr_unix -I./sr_linux buildtypes=pro gtm_ver=$PWD
#
#    By default the build procedure will build 64 bit version of GT.M
#    on a x86_64 machine.
#    If you intend to build 32 bit version of GT.M on a x86_64 bit machine you
#    have to explicitly set the environment variable 'OBJECT_MODE' to '32'
#    Example:
#        OBJECT_MODE=32; export OBJECT_MODE #bourne shell
#        export OBJECT_MODE=32              #bash shell
#        setenv OBJECT_MODE 32              #tcsh shell
#
#   This procedure requires the tcsh shell to be installed.
