添加BIOS系统出现符号重定义



我在源程序中添加了下述部分

#include <log.h>

extern LOG_Obj trace;

LOG_printf(&trace,"Switest example started!\n");

 

编译之后在linking过程中出现的问题如下

undefined first referenced                                                

 symbol       in file                                                    

--------- ----------------                                                

_trace    D:\\workspace\\MuPro\\tests\\omapl138_main\\ccs\\Debug\\main.obj

error: unresolved symbols remain

error: errors encountered during linking; "./Debug/138_main.out" not built

>> Compilation failure

使用的开发平台是CCS3.3+OMAPL138平台+XDS560plus仿真器。BIOS版本5.41.02.14.

以上问题,不知道是不是BIOS版本问题,查找了CMD文件也找不到答案,希望得到指点。
