Question

我在Windows中使用Matlab（2018a）困扰Armadillo（armadillo-8.500.1）中的armaMex_demo_cpp。

到目前为止，我正在尝试命令：

>> mex -LC:\Users\Test\Documents\Armadillo\armadillo-8.500.1-mod_for_windows\include\armadillo -LC:\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin\gfortran -IC:\Users\Test\Documents\Armadillo\armadillo-8.500.1-mod_for_windows\include armaMex_demo.cpp

并获取错误消息（被截断）：

有人对我在这里做错什么有任何想法吗？

有人能在Windows中为armaMex_demo.cpp构建mex文件吗？

Answer 1

似乎与我包含/引用BLAS的方式有关。我以前在config.hpp中没有注释“ #define ARMA_USE_BLAS”行。通过此mex命令，将其注释为I：

mex -LC：\ Users \ Test \ Documents \ Armadillo \ armadillo-8.500.1-mod_for_windows \ include \ armadillo -LC：\ mingw-w64 \ i686-8.1.0-posix-dwarf-rt_v6-rev0 \ mingw32 \ bin \ gfortran -IC：\ Users \ Test \ Documents \ Armadillo \ armadillo-8.500.1-mod_for_windows \ include armaMex_demo.cpp

我只会收到此错误：

使用“ Microsoft Visual C ++ 2017”构建。

使用mex时出错 armaMex_demo.cpp C：\ Users \ Test \ Documents \ Armadillo \ armadillo-8.500.1-mod_for_windows \ mex_interface \ armaMex_demo.cpp（44）：错误C2668：'arma :: size'：歧义调用重载功能

c：\ users \ test \ documents \ armadillo \ armadillo-8.500.1-mod_for_windows \ include \ armadillo_bits / fn_size.hpp（38）：注意：可能是'const

Answer 2

并通过更改行

如果（size（X）！= size（Y））

到

if（X.size（）！= Y.size（））

在armaMex_demo.cpp中

混合（和mex调用）可在Windows中从Matlab运行。

Matlab mex命令在Windows的Armadillo中构建armaMex_demo.cpp
