From 25697773b529d80278679978b7416ca9c87e15e9 Mon Sep 17 00:00:00 2001 From: Martin Mares Date: Fri, 15 May 1998 07:56:13 +0000 Subject: [PATCH] The library is now glued together from generic and OS-dependent parts by the `mergedirs' script. Few more IP address manipulation functions and some fixes. --- Makefile | 19 ++++++++++++++----- Rules | 29 ++++++++++++++++++++++------- lib/Makefile | 9 --------- lib/Modules | 19 +++++++++++++++++++ lib/birdlib.h | 4 ++-- lib/ip.h | 6 ++++++ lib/ipv4.c | 4 ++++ lib/ipv4.h | 6 +++--- lib/ipv6.c | 4 ++++ lib/ipv6.h | 2 ++ sysdep/cf/linux-20.h | 4 ++++ sysdep/cf/linux-21.h | 4 ++++ sysdep/cf/linux-v6.h | 4 ++++ sysdep/linux/Makefile | 1 - sysdep/linux/Modules | 0 sysdep/unix/Makefile | 3 --- sysdep/unix/Modules | 3 +++ sysdep/unix/main.c | 25 +++++++++++++++++++++++++ {lib => sysdep/unix}/timer.h | 0 tools/mergedirs | 36 ++++++++++++++++++++++++++++++++++++ 20 files changed, 152 insertions(+), 30 deletions(-) delete mode 100644 lib/Makefile create mode 100644 lib/Modules delete mode 100644 sysdep/linux/Makefile create mode 100644 sysdep/linux/Modules delete mode 100644 sysdep/unix/Makefile create mode 100644 sysdep/unix/Modules create mode 100644 sysdep/unix/main.c rename {lib => sysdep/unix}/timer.h (100%) create mode 100755 tools/mergedirs diff --git a/Makefile b/Makefile index 45e69afa..3a74205b 100644 --- a/Makefile +++ b/Makefile @@ -2,32 +2,41 @@ # (c) 1998 Martin Mares TOPDIR=$(shell pwd) +OBJDIR=obj + CPPFLAGS=-I$(TOPDIR)/sysdep/linux -I$(TOPDIR) OPT=-O2 DEBUG=-g#gdb CFLAGS=$(OPT) $(DEBUG) -Wall -W -Wstrict-prototypes -Wno-unused -Wno-parentheses PROTOCOLS= -DIRS=nest $(PROTOCOLS) lib sysdep/linux sysdep/unix -ARCHS=$(join $(addsuffix /,$(DIRS)),$(subst /,_,$(addsuffix .a,$(DIRS)))) +LIBDIRS=sysdep/linux sysdep/unix lib +STDDIRS=nest $(PROTOCOLS) +DIRS=$(STDDIRS) $(OBJDIR)/lib +PARTOBJS=$(join $(addsuffix /,$(STDDIRS)),$(subst /,_,$(addsuffix .o,$(STDDIRS)))) +LIBS=$(OBJDIR)/lib/birdlib.a export all: .dep all-dirs bird all-dirs: - set -e ; for a in $(DIRS) ; do $(MAKE) -C $$a ; done + set -e ; for a in $(DIRS) ; do $(MAKE) -C $$a all ; done -bird: $(ARCHS) +bird: $(PARTOBJS) $(LIBS) $(CC) $(LDFLAGS) -o $@ $^ .dep: $(MAKE) dep - touch .dep dep: + mkdir -p $(OBJDIR) + tools/mergedirs $(OBJDIR) $(LIBDIRS) +# for a in $(STDDIRS) ; do mkdir -p $(OBJDIR)/$$a ; done set -e ; for a in $(DIRS) ; do $(MAKE) -C $$a dep ; done + touch .dep clean: + rm -rf obj rm -f `find . -name "*~" -or -name "*.[oa]" -or -name "\#*\#" -or -name TAGS -or -name core -or -name .depend -or -name .#*` rm -f bird .dep diff --git a/Rules b/Rules index a0a1418a..2d9c0a8a 100644 --- a/Rules +++ b/Rules @@ -3,17 +3,32 @@ THISDIR=$(shell pwd) RELDIR=$(subst $(TOPDIR)/,,$(THISDIR)) -ANAME=$(subst /,_,$(RELDIR)).a +ONAME=$(subst /,_,$(RELDIR)).o + +ifndef SRCS SRCS=$(subst .o,.c,$(OBJS)) - -all: $(ANAME) - -$(ANAME): $(OBJS) - rm -f $(ANAME) - ar rcs $(ANAME) $(OBJS) +endif ifdef OBJS +ifdef LIB + +all: $(LIB) + +$(LIB): $(OBJS) + rm -f $(LIB) + ar rcs $(LIB) $(OBJS) + ranlib $(LIB) + +else + +all: $(ONAME) + +$(ONAME): $(OBJS) + $(LD) -r -o $(ONAME) $(OBJS) + +endif + dep: $(SRCS) rm -f .depend for a in $(SRCS) ; do gcc $(CPPFLAGS) -MM $$a >>.depend ; done diff --git a/lib/Makefile b/lib/Makefile deleted file mode 100644 index 6eb14e1e..00000000 --- a/lib/Makefile +++ /dev/null @@ -1,9 +0,0 @@ -OBJS=lists.o bitops.o resource.o xmalloc.o mempool.o slab.o md5.o - -ifdef IPV6 -OBJS += ipv6.o -else -OBJS += ipv4.o -endif - -include $(TOPDIR)/Rules diff --git a/lib/Modules b/lib/Modules new file mode 100644 index 00000000..18447e1e --- /dev/null +++ b/lib/Modules @@ -0,0 +1,19 @@ +birdlib.h +bitops.c +bitops.h +ip.h +ipv4.c +ipv4.h +ipv6.c +ipv6.h +lists.c +lists.h +md5.c +md5.h +mempool.c +resource.c +resource.h +slab.c +socket.h +unaligned.h +xmalloc.c diff --git a/lib/birdlib.h b/lib/birdlib.h index 5e533b66..842fce86 100644 --- a/lib/birdlib.h +++ b/lib/birdlib.h @@ -21,8 +21,8 @@ /* Logging and dying */ -void log(char *msg, ...); -void die(char *msg, ...)
