The default compilation mode for Sun compilers that support the 46# C99 standard is -xc99=all,no_lib. CSTD= is equivalent to -xc99=all,no_lib. 47# This translates to C99 semantics without the C99 library specific behaviors 48# and dependencies. 49# 50# For pre-5.7 compilers (unless patched with 117551-04 or 117552-05), in the 51# default compilation mode, __STDC_VERSION__ was defined to be 199901L. For 52# 5.7 and on compilers, __STDC_VERSION__ defaults to 199409L in order to 53# maintain source compatibility. Neither of these cases results in the 54# importing of /usr/lib/values-xpg6.o, so we need to either manually import 55# it via linking with a local version of the object, or set -xc99=%all which 56# by default imports /usr/lib/values-xpg6.o. CSTD=CSTD_GNU99 is equivalent 57# to -xc99=all. If CSTD_GNU99 is defined and we also attempt to link with a 58# local version of values-xpg6.o, an error will occur due to multiple 59# definitions for __xpg4 and __xpg6. Because /usr/lib/values-xpg6.o was 60# delivered in Solaris 10 and is a stable interface, there is no need to 61# build and link with a local version of the object. 62# 63# The gcc compiler behaves differently and requires -std=gnu99. 64# 65# For XPG4, we need to link with a local version of values-xpg4.o because 66# the compiler only imports this by default (from /usr/lib/values-xpg4.o) 67# if we use the c89 utility as opposed to cc. 68 69XPG6MODE = $(CSTD_GNU99) 70$(XPG6) := CSTD = $(XPG6MODE) 71$(XPG6) := CFLAGS += -D_XOPEN_SOURCE=600 -I$(SRC)/lib/libc/inc 72 73.KEEP_STATE: 74 75all: $(PROG) $(XPG4) $(XPG6) 76 77$(PROG): $(OBJS) 78 $(LINK.c) -o $@ $(OBJS) $(LDLIBS) 79 $(POST_PROCESS) 80 81$(XPG4): $(X4) $(XPG4EXOBJS) 82 $(LINK.c) -o $@ $(XPG4EXOBJS) $(LDLIBS) 83 $(POST_PROCESS) 84 85$(XPG6): $(X6) $(XPG6EXOBJS) 86 $(LINK.c) -o $@ $(XPG6EXOBJS) $(LDLIBS) 87 $(POST_PROCESS) 88 89 90$(XPG4EXOBJS): $(X4) 91 92 93$(X4)/%.o: %.c 94 $(COMPILE.c) -o $@ $< 95 96 97$(X4): 98 -@mkdir -p $@ 99 100 101$(XPG6EXOBJS): $(X6) 102 103 104$(X6)/%.o: %.c 105 $(COMPILE.c) -o $@ $< 106 107 108$(X6): 109 -@mkdir -p $@ 110 111 112install: all $(ROOTPROG) $(ROOTXPG4PROG) $(ROOTXPG6PROG) 113 114values-xpg4.o: ../../lib/crt/common/values-xpg4.c 115 $(COMPILE.c) -o $@ ../../lib/crt/common/values-xpg4.c 116 117clean: 118 -@rm -rf $(OBJS) $(XPG4EXOBJS) $(XPG6EXOBJS) $(X4) $(X6) \ 119 $(PROG) $(XPG4) $(XPG6) 120 121lint: lint_PROG 122 123include ../Makefile.targ 124
