# make file for "flex" tool
|
|
|
|
# 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;
