这是更动过之后的makefile
ARFLAGS := rcv
AR := ar
default: lib //这行是多加的
$(OBJ_FILES)
@$(CXX) $(CXXFLAGS) $(OBJ_FILES) -o $(TARGET)
@echo " LD $(TARGET)"
lib: libcircuit.a
libcircuit.a: $(OBJ_FILES)
$(AR) $(ARFLAGS) libcircuit.a $(OBJ_FILES)
厄..不知道问题出在哪边,麻烦助教了～"～

这个是我执行完make的画面～

你冒号后面有用tab吗?执行的log?

冒号后是指libcircuit.a:下面那一行吗?那边有tab像lib:旁边是用空白再加上libcircuit.a

你没灌lex和yacc .... comamnd not found..*command

我有把flex跟bison这两个东西载下来但一直不知道怎么用...

sudo apt-get install这两样就OK了

看这一串讨论就觉得幸好我没去改lib

不过不是建议即使没改还是要写makefile一起compile吗？
