make[3]: *** [obj/armv4-le-elf/hal.mangle] Error 1

我将makefile中的"-o"删除掉，又报错说“没有文件obj/armv4-le-elf/t.o”，到底该怎样解决这个问题啊？

帮帮忙啊，兄弟们！

没用过这个东西，不太清楚

njlinuxer

在终端看看 file obj/armv4-le-elf/hal.o 的结果是？
make不是已经列出了supported targets

samon_fu

arm-elf-strip --strip-unneeded -o obj/armv4-le-elf/t.o obj/armv4-le-elf/hal.o

换成

arm-elf-strip --strip-unneeded obj/armv4-le-elf/hal.o -o obj/armv4-le-elf/t.o

这样试一下呢？你这个命令估计实现参数分析的时候没那么标准，呵呵

samon_fu

你这两个参数 obj/armv4-le-elf/t.o obj/armv4-le-elf/hal.o  是啥意思？

把hal.o文件strip成t.o文件还是？

T-bagwell

楼主是想strip多个文件还是把后者strip成前者啊?
