# Note: this is a modified version of Makefile, for ACK installation. The # original flex makefile has a capital M (Makefile). EMHOME = ../.. # 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 # 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.
