Matlab mex“缺少依赖的共享库" [英] Matlab mex "Missing dependent shared libraries"

问题描述

我在Matlab 2017a中创建了几个mex文件.当我使用Visual Studio C ++ 2017编译它们时，它们在我的计算机上运行良好.但是，当我尝试在另一台计算机上使用它们时，出现错误消息

I have a couple mex files I'm creating in Matlab 2017a. When I compile them with Visual Studio C++ 2017, they run fine on my computer. However, when I attempt to use them on another computer, I get an error that says

Error using mfss_mex.filter_uni
Invalid MEX-file  
'path_to_mex_file\mexfile.mexw64':
Missing dependent shared libraries:
'MSVCP140.dll' required by
'path_to_mex_file\mexfile.mexw64'
'VCRUNTIME140.dll' required by
'path_to_mex_file\mexfile.mexw64'

我想我可以通过在将要运行的每台计算机上安装Visual Studio运行时来解决此问题，但我想避免这种情况.有没有办法使用Visual Studio C ++编译器来编译这些mex文件并避免这些依赖关系?

I think I could resolve this by installing the Visual Studio runtime on every computer this will get run on but I'd like to avoid that. Is there a way to compile these mex files and avoid these dependencies with the Visual Studio C++ compiler?

推荐答案

Mathworks

The Mathworks solution to this is to install the C++ compiler runtime on any computer that has this issue.

我发现我只需要将有问题的.dll文件(MSVCP140.dll和VCRUNTIME140.dll)复制到与我的.mexw64文件相同的文件夹中，一切就不会有问题.

I found that I simply needed to copy the offending .dll files (MSVCP140.dll and VCRUNTIME140.dll) into the same folder with my .mexw64 files and everything ran without a problem.
