您好！

我在将F28P55x_rfft_fpu32历程迁移到自己的工程文件时编译出现如下所示问题：

例程中没有RFFT_f32_sincostabled的定义，fpu_rfft.h中定义了

extern void RFFT_f32_sincostable(RFFT_F32_STRUCT_Handle hndRFFT_F32);

程序引用了fpu_rfft.h，但还是报上述故障，请问是什么原因导致的？例程没有这个问题。

您好，

hongwei liu 说：
warning #10204-D: could not resolve index library "c28x_fpu_dsp_library.lib" to a compatible library

应该是兼容问题。

您工程中所有引用的库都是支持FPU的吗（floating-point libraries）？

我发现在F28P55x_rfft_fpu32例程中加入USB功能就会出现类似问题，如下：
