【问题描述】：

我在关注this tutorial 时遇到此错误：

ld: warning: ignoring file /project/lib/libdlib.a, file was built for archive which is not the architecture being linked (arm64): /project/lib/libdlib.a
Undefined symbols for architecture arm64:
  "_cblas_dgemm", referenced from:
      dlib::blas_bindings::cblas_gemm(dlib::blas_bindings::CBLAS_ORDER, dlib::blas_bindings::CBLAS_TRANSPOSE, dlib::blas_bindings::CBLAS_TRANSPOSE, int, int, int, double, double const*, int, double const*, int, double, double*, int) in DlibWrapper.o

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我能做什么？

【问题讨论】：

添加构建设置 -> 架构到标准架构（armv7、armv7s、arm64）。

@Anbu.Karthik 在 dlib 项目中还是在我的项目中？

检查两个.....

请参阅此参考：***.com/questions/20926632/…

@Anbu.Karthik 没有帮助，同样的错误:(

【参考方案1】：

添加加速框架

对于 ios 和 macOS 平台，框架包含符号。
