# make file for "flex" tool (modified to work with Lattice 5.05)

# @(#) $Header: /usr/fsys/odin/a/vern/flex/RCS/Makefile,v 2.9 90/05/26 17:28:44 vern Exp $ (LBL)

# Porting considerations:
#
#    For System V Unix machines, add -DUSG to CFLAGS (if it's not
#         automatically defined)
#    For Vax/VMS, add "-DVMS -DUSG" to CFLAGS.
#    For MS-DOS, add "-DMS_DOS -DUSG" to CFLAGS.  Create \tmp if not present.
#         You will also want to rename flex.skel to something with a three
#         character extension, change SKELETON_FILE below appropriately,
#	  See MSDOS.notes for more info.
#    For Amiga, add "-DAMIGA -DUSG" to CFLAGS.
#    For SCO Unix, add "-DSCO_UNIX" to CFLAGS.
#
#    For C compilers which don't know about "void", add -Dvoid=int to CFLAGS.
#
#    If your C compiler is ANSI standard but does not include the <stdlib.h>
#    header file (some installations of gcc have this problem), then add
#    -DDONT_HAVE_STDLIB_H to CFLAGS.
#
# By default, flex will be configured to generate 8-bit scanners only
# if the -8 flag is given.  If you want it to always generate 8-bit
# scanners, add "-DDEFAULT_CSIZE=256" to CFLAGS.  Note that doing
# so will double the size of all uncompressed scanners.
# 
# If on your system you have trouble building flex due to 8-bit
# character problems, remove the -8 from FLEX_FLAGS and the
# "#define FLEX_8_BIT_CHARS" from the beginning of flexdef.h.


# the first time around use "make first_flex"


# Installation targeting.  Files will be installed under the tree rooted
# at DESTDIR.  User commands will be installed in BINDIR, library files
# in LIBDIR (which will be created if necessary), auxiliary files in
# AUXDIR, manual pages will be installed in MANDIR with extension MANEXT.
# Raw, unformatted troff source will be installed if INSTALLMAN=man, nroff
# preformatted versions will be installed if INSTALLMAN=cat.
