在R2018b中安装matconvnet 1.0-beta24文件

Question

我想在MATLAB中运行mex -setup，但首先我必须从MatConvNet版本的matconvnet-1.0-beta24运行vl_compilenn。当我运行vl_compilenn时，我得到以下错误：

C:/ProgramData/MATLAB/SupportPackages/R2018b_1/3P.instrset/mingw_w64.instrset/lib/gcc/x86_64-w64-mingw32/6.3.0/include/tmmintrin.h:

Error in vl_compilenn>mex_compile (line 529)
mex(mopts{:}) ;

Error in vl_compilenn (line 490)
    mex_compile(opts, srcs{i}, objfile, flags.mexcc) ;

对此我们能做些什么呢？

Answer 1

根据doc of gcc intrinsics，您必须使用'-mssse3‘标志进行编译。

我会尝试将此标志添加到编译标志集flags.mexcc中。我不能给你更多的细节，因为主控已经从你的版本进化而来，脚本vl_compilenn也进化了。
