求教Makefile高手一个问题?

程序目录结构: ./main/main.c ./src/sub.c

E,p8jl u 输出:                 ./out/his/    ./out/main/

E.@3e1P ---------------------------------------------------------------------------------
E0m] n@ 使用下面两行:

h!E8gi
$(eval $(call one-compile-rule,./out/src/sub.o,./src/sub.c)).D(s/so'Zi
一切正常,生成.o文件(./out/his/    ./out/main/下),生成可执行程序$(program).hI&jYn+D
---------------------------------------------------------------------------------8US"n%^-v{m6i
上面两行不使用换成下面:\4CF~D

怪哉怪哉,高手们指点指点,到底哪错了?万分感谢E&YNP-l_X
