丢失分隔符问题

Question

在此文件中获取此错误makefile:4: *** missing separator. Stop.

PROC=findcrypt
O1=consts
O2=sparse
!include ..\plugin.mak
# MAKEDEP dependency list ------------------
$(F)consts$(O)  : $(I)llong.hpp $(I)pro.h consts.cpp findcrypt.hpp

          $(I)help.h $(I)ida.hpp $(I)idp.hpp $(I)kernwin.hpp        \

$(F)sparse$(O)  : $(I)llong.hpp $(I)pro.h findcrypt.hpp sparse.cpp

我已尝试使用cat -e -t -v makefile来识别不良标签，但从我能说的内容看起来一切正常。
