makefile

从网上下载的一个自己编写的简单的操作系统源代码,对底层了解很有好处的

#
#
#
#
#  负责编译 引导记录 和 setup.bin
#
#
#


setupo = setup.o  setup/detectmem.o setup/setupvga.o setup/8259.o



# 此makefile的最终任务
boot:fsector.bin setup.bin
	$(CP) fsector.bin  ..\build
	partcopy setup.bin 0 1  setup.bin 7ff  
	$(CP) setup.bin    ..\build


# 编译引导记录
fsector.bin: fsector.s
	$(AS) -o $@ $<


# 编译setup.bin, 有点特殊
setup.bin: $(setupo)
	$(LD) $(LDFLG) $(setupo) -Ttext 0x0 -e setup_entry -O binary -o setup.binary 
	objcopy -R .comment -R .note -S -O binary  setup.binary  $@
	


# 默认规则
%.o:%.s
	$(AS) -f aout -o $@ $<

#
#
#
clean:
	$(RM) *.o
	$(RM) *.binary
	$(RM) setup\*.o
	$(RM) fsector.bin 
	$(RM) setup.bin
