新人，遇到一个问题，一直找不出原因，求解答undefined symbol in debug/*.obj
DSP/BIOS中测试log程序，一个简单的LOG_printf（）函数输出程序，BIOS配置没有问题，并且将一系列源文件和头文件已添加，编译通过，连接时出现以下错误："C:\CCStudio_v3.3\C6000\cgtools\bin\cl6x" -@"Debug.lkf"

一直搞不明白出错的原因，求各位大神指导！ 在.cmd文件里加上
-lbios.a64P /* DSP/BIOS support */
根据不同CPU选择不同的后缀 先试试楼上建议的方法

你好！我按你说的在.cmd文件中加上-lbios.a64e,编译通过，连接时出现以下错误：

出现这个问题的原因是，工程中的cmd文件时自己写的，将自己写的cmd文件替换成BIOS配置时自动生成的*cfg.cmd文件后，连接出现：
"C:\CCStudio_v3.3\C6000\cgtools\bin\cl6x" -@"Debug.lkf"

请教各位大神，这是什么原因？按理来说，link自动生成的cmd文件，链接应该没问题的 出现问题的原因是：cmd文件不完善等各种原因，还在探索。 myduanning 发表于 2014-3-24 20:58 static/image/common/back.gif

不行先找个例程跑跑然后用哪个cmd再慢慢修改 先按版主的试试，这个问题我也遇到过。
1.先把LIB文件加入
2.程序有语法错误，一个个排查了。
