编译错误：undefined reference to

bobodu

编译的时候出现很多这样的错误：
undefined reference to 'strcpy'
undefined reference to 'readcontrol'
......................................
edu$(TARGET).bin : $(DIAGS_SOBJ) $(DIAGS_COBJ) $(HFILES) $(CFILES) $() $(LIBS)$(TCAM_OBJS)

        objcopyarm -O binary edu$(TARGET).tmp edu$(TARGET).bin     [/color]#####error in this line

makefile文件中上面蓝色的那行出错，各模块单独编译均能通过，请各位指点一下，谢谢

#include <string.h>
有这个头吗

这个应该是正解
objcopyarm -O binary edu$(TARGET).tmp edu$(TARGET).bin
上面这一句应该只是把tmp文件专为二进制的文件，方便烧写而已

感谢各位的回复
string.h肯定有的，因为在tornado2.0上编译都能通过的，上面的结果是在tornado2.2环境下编译的，错误就是一堆undefined reference to ...

上面的分析没有错，我看makefile的时候，到这句就开始出现undefined reference to 。。。错误，我不知道是哪出错了

是你没有链接C库造成的

web_serf,你好，能说得具体一点吗？要链接什么样的C库？

在ld时，加上-lc试试
