# Descrip.MMS -- Makefile for building GNU Awk on VMS with VAXC and MMS.
#
# usage:
# $ MMS /Description=[.vms]Descrip.MMS gawk
#
# gawk.exe :
# You'll need to modify this Makefile to use gcc or vaxc v2.x rather
# than vaxc v3.x. Change the CFLAGS macro definition (move '#' from
# beginning of 2nd alternative to beginning of 1st), and also perhaps
# enable the following ".first" rule and its associated action. For
# GNU C, change the LIBS macro definition.
#
# awktab.c :
# If you don't have bison but do have VMS POSIX or DEC/Shell,
# change the PARSER and PASERINIT macros to use yacc. If you don't
# have either yacc or bison, you'll have to make sure that the
# distributed version of "awktab.c" has its modification date later
# than the date of "awk.y", so that MMS won't try to build that
# target. If you use bison and it is already defined system-wide,
# comment out the PARSERINIT definition.
#
# install.help :
# You can make the target 'install.help' to load the VMS help text
# into a help library. Modify the HELPLIB macro if you don't want
# to put entry into the regular VMS library. (If you use an alternate
# help library, it must already exist; this target won't create it.)
#
# gawk.dvi :
# If you have TeX, you can make the target 'gawk.dvi' to process
# _The_GAWK_Manual_ from gawk.texi. You'll need to use a device
# specific post-processor on gawk.dvi in order to get printable data.
#
# location of the VMS-specific files, relative to the 'main' directory

MAKEFILE = $(VMSDIR)Descrip.MMS

# beta VAX/VMS -> Alpha/VMS cross-compiler
#CC = gemcc/Standard=VAXC/G_Float
# Alpha/VMS

# uncomment these two lines for GNU C _if_ it's not installed system-wide
#.first !compiler init, needed if there's no system-wide setup
# set command gnu_cc:[000000]gcc
# uncomment these three lines for VAX C V2.x
#.first !compiler init, find all #include files
# define/nolog vaxc$library sys$library:,sys$disk:$(VMSDIR)
# define/nolog c$library [],$(VMSDIR)
#!(it appears that if vaxc$library is defined, then the /Include
#! qualifier is ignored, making a c$library definition essential)
