1# 2# By default, flex will be configured to generate 8-bit scanners only if the 3# -8 flag is given. If you want it to always generate 8-bit scanners, add 4# "-DDEFAULT_CSIZE=256" to CFLAGS. Note that doing so will double the size 5# of all uncompressed scanners. 6# 7# Bootstrapping of lex is handled automatically. 8# Also note that flex.skel no longer gets installed. 9# 10 11PROG= lex 12LINKS+= ${BINDIR}/lex ${BINDIR}/lex++ 13LINKS+= ${BINDIR}/lex ${BINDIR}/flex 14LINKS+= ${BINDIR}/lex ${BINDIR}/flex++ 15 16FLEXDIR= ${SRCTOP}/contrib/flex/src 17 18.PATH: ${FLEXDIR} 19 20SRCS= buf.c ccl.c dfa.c ecs.c filter.c gen.c main.c misc.c \ 21 nfa.c options.c parse.y regex.c scan.c scanflags.c \ 22 scanopt.c skel.c sym.c tables.c tables_shared.c \ 23 tblcmp.c yylex.c 24LFLAGS+= -is 25CFLAGS+= -I. -I${.CURDIR} -I${FLEXDIR} -DHAVE_CONFIG_H 26INCS= FlexLexer.h 27INCSDIR= ${INCLUDEDIR} 28MLINKS+= lex.1 flex.1 29MLINKS+= lex.1 flex++.1 30MLINKS+= lex.1 lex++.1 31 32WARNS?= 3 33 34NO_WMISLEADING_INDENTATION= 35 36CLEANFILES= scan.c skel.c 37GENFILES= parse.c parse.h scan.c skel.c 38 39SUBDIR= lib 40 41FLEX_VERSION= `awk -f ${.CURDIR}/version.awk ${.CURDIR}/config.h` 42 43skel.c: config.h mkskel.sh flex.skl version.awk 44 sh ${FLEXDIR}/mkskel.sh ${FLEXDIR} m4 ${FLEX_VERSION} > ${.TARGET} 45 46bootstrap: ${GENFILES:S/^/init/g} 47.for _f in ${GENFILES} 48 @diff -I '^#line ' -I '\$$FreeBS[D]: .*\$$' -q \ 49 ${.CURDIR}/init${_f} ${_f} 2> /dev/null || { \ 50 echo "Bootstrapping ${_f}" ; \ 51 ${CP} ${.CURDIR}/init${_f} ${_f} ; \ 52 } 53.endfor 54 55test: check 56check: ${PROG} 57 ./${PROG} ${LFLAGS} -t ${COMPRESSION} ${FLEXDIR}/scan.l | \ 58 diff -I '^#line ' -I '\$$FreeBS[D]: .*\$$' ${.CURDIR}/initscan.c - 59 @echo "Check successful" 60 61.include <bsd.prog.mk> 62
