- # make file for "flex" tool
- # @(#) $Id$ (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.
