linux - 谁能给我解释一下这个 makefile 示例吗？

Question

# Makefile to compare sorting routines

BASE = /home/blufox/base
CC = gcc
CFLAGS = -O –Wall
EFILE = $(BASE)/bin/compare_sorts
INCLS = -I$(LOC)/include
LIBS = $(LOC)/lib/g_lib.a \
$(LOC)/lib/h_lib.a
LOC = /usr/local
OBJS = main.o another_qsort.o chk_order.o \
compare.o quicksort.o

$(EFILE): $(OBJS)
    @echo “linking …”
    @$(CC) $(CFLAGS) –o $@ $(OBJS) $(LIBS)

$(OBJS): compare_sorts.h
    $(CC) $(CFLAGS) $(INCLS) –c $*.c

# Clean intermediate files
clean:
    rm *~ $(OBJS)

Answer 1

变量替代形式，gcc -O –Wall -o/home/blufox/base/bin/compare_sorts main.o another_qsort.o chk_order.o 比较.o 快速排序.o main.c another_qsort.c chk_order.c 比较.c例如:$(OBJS) = main.o another_qsort.o chk_order.o 比较.o 快速排序.o
