ios - 生成SDK时链接错误

我正在尝试使用与音频相关的框架来生成SDK，当编译代码低于链接错误时。解决这些问题的任何帮助。

Undefined symbols for architecture armv7:
  "_vDSP_ztoc", referenced from:
      FFTRealCalculator::InverseFFT_A(ComplexSplit*, float*, int) in libEywaSDK.a(FFTRealCalculator.o)
  "_vDSP_ctoz", referenced from:
      FFTRealCalculator::ForwardFFT_A(float const*, unsigned long, ComplexSplit*) in libEywaSDK.a(FFTRealCalculator.o)
  "_vDSP_fft_zrip", referenced from:
      FFTRealCalculator::ForwardFFT_A(float const*, unsigned long, ComplexSplit*) in libEywaSDK.a(FFTRealCalculator.o)
      FFTRealCalculator::InverseFFT_A(ComplexSplit*, float*, int) in libEywaSDK.a(FFTRealCalculator.o)
  "_vDSP_create_fftsetup", referenced from:
      FFTRealCalculator::Initialize(unsigned char) in libEywaSDK.a(FFTRealCalculator.o)
  "_vDSP_destroy_fftsetup", referenced from:
      FFTRealCalculator::~FFTRealCalculator() in libEywaSDK.a(FFTRealCalculator.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

最佳答案

这些符号来自Accelerate Framework

我怀疑您需要将此添加到您的项目中。
