问一个关于Makefile 的问题

970361 2003-08-21 03:10:00

我写了一个makefile文件，但是我想把把 *.c放在src目录，把*.o放在 obj/目录里面请问该如何写啊？

#makefile 如下，请各位知道的大虾指点一下
PROJS =myprog

OBJS := $(patsubst %.c, %.o,$(wildcard *.c))

CFLAGS += -c -O -O2 -g -D__LINUX__ -I/usr/include/mysql -I./include
CFLAGS += -DGS_DEBUG
LFLAGS = -lmysqlclient

all: $(PROJS)

$(PROJS): $(OBJS)
$(CC) -o $(PROJS) $(LIBS) $(OBJS) $(LDFLAGS) $(LFLAGS)

.c.o:
$(CC) $(INCLUDE) $(CFLAGS) -o $*.o $<

clean:
rm -f *.o *.BAK core $(PROJS) $(PROJS).res

depend:
$(CC) -E -M $(INCLUDE) *.c >.depend

ifeq (.depend, $(wildcat .depend))
include .depend
endif

为了表示对各位的感谢，
我把修改好的Makefile 贴出来

# This is new version of make
# you need only copy you *.c file to ./src/
# and copy *.h to ./include/
# makefile is so smart that he can find all *.c file to compile
#
# But notice!!! PLEASE REMOVE c file FROM ./src that you NEEDN'T compile

OBJDir = $(TOPDIR)/obj
