多谢！
Eason Wang：
检查一下Rules.make中路径是否正确？
roger zhu：
回复 Eason Wang:
谢谢！指哪个路径？
rules.mk里的内容如下：
_depend: $(obj).depend
$(obj).depend: $(src)Makefile $(TOPDIR)/config.mk $(SRCS) $(HOSTSRCS)
@rm -f $@
@for f in $(SRCS); do \
g=`basename $$f | sed -e 's/\(.*\)\.\w/\1.o/'`; \
$(CC) -M $(CPPFLAGS) -MQ $(obj)$$g $$f >> $@ ; \ done
@for f in $(HOSTSRCS); do \
g=`basename $$f | sed -e 's/\(.*\)\.\w/\1.o/'`; \ $(HOSTCC) -M $(HOSTCPPFLAGS) -MQ $(obj)$$g $$f >> $@ ; \ done
$(HOSTOBJS): $(obj)%.o: %.c
$(HOSTCC) $(HOSTCFLAGS) $(HOSTCFLAGS_$(@F)) $(HOSTCFLAGS_$(BCURDIR)) -o $@ $< -c$(NOPEDOBJS): $(obj)%.o: %.c
$(HOSTCC) $(HOSTCFLAGS_NOPED) $(HOSTCFLAGS_$(@F)) $(HOSTCFLAGS_$(BCURDIR)) -o $@ $< -c
另外，我编译helloworld是正常的。谢谢！
roger zhu：
回复 Eason Wang:
只要关闭终端，再次开启，编译器的路径就从$PATH消失了。多谢！
