ton*_*gko 4 c linux makefile gnu-make
由于未知原因,GNU Make不能为我完成这项工作.我有这个MAKE文件,我确实为每个食谱,我使用标签,而不是空间.但是我看着它,我无法发现会导致错误信息的任何地方.
操作系统:Ubuntu 17.10/GNU Make:4.1/GCC:交叉编译到i686-elf-gcc.
运行它:make(在同一目录中)给我
make: *** No rule to make target '%.o', needed by 'kernel.elf'. Stop.
我有一个bash脚本,完全相同的东西,它就像魅力一样.谁能说出我做错了什么？

问题在于以下规则:
kernel.elf : %.o
GNU Make实际上%.o是一种先决条件,而不是一种模式.
我建议你定义一个obj包含目标文件名称的变量,并将规则重写为:
kernel.elf: $(obj)
这种obj变量的定义可以是:
obj := $(patsubst %.c,%.o,$(wildcard *.c))
obj += $(patsubst %.asm,%.so,$(wildcard *.asm))
