C6713调用DSPF_sp_lms库函数出错



您好:

 我在做音频信号的LMS滤波的工程中,使用的是6713的芯片,在调用库函数DSPF_sp_lms的时候,编译出现错误:_DSPF_sp_lms                     D:\\project_mgy\\dsp_project\\Audio_LMS\\Audio_LMS\\Debug\\mainfilter.obj
>>   error: symbol referencing errors - './Debug/iir.out' not built

我的头文件包含了这个函数的定义文件,也加进去库了,请问是什么原因导致出现此种报错?谢谢
