IQMATHE 某些函数调用出错

Other Parts Discussed in Thread: TMS320C6455

您好!

我最近在用TMS320C6455的定点DSP,我用的CCS版本是:CCS V3.3,编译器版本是:Compliesr 6.1.20;BIOS版本是5.41.11.38。我需要用到的_IQNpow(),_IQNlog(),_IQNtoF()三个函数无法正常使用,编译时会报一些引用未定义的错误,错误信息如下:undefined first referenced                                

 symbol       in file                                      

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

 __IQlog   F:\\6455CODE_DSP\\IQ_TEST2\\Debug\\iqtestmain.obj

__IQpow   F:\\6455CODE_DSP\\IQ_TEST2\\Debug\\iqtestmain.obj

__IQtoF   F:\\6455CODE_DSP\\IQ_TEST2\\Debug\\iqtestmain.obj

error: unresolved symbols remain

error: errors encountered during linking; "./Debug/IQ_TEST2.out" not built。

但是我看源代码中,没有出现过错误中所报的未引用的符号,这些函数的预处理开关已经打开。请赐教,谢谢!
