Question

我正在尝试使用Matlab Coder工具将一些matlab代码转换为c动态库（.dll）。我正在尝试一些简单的示例代码，但我一直得到同样的错误，我无法找到解决方案。

我的代码是：

function y = lbryTest(x, z) %#codegen
%QUICKTEST Summary of this function goes here
%   Detailed explanation goes here
y = 1.0;
a = x + z;
b = x * a;
y = b/3 + y;
end

我尝试过使用应用程序版本的编码器以及命令：codegen -config:dll lbryTest -args {2.0, 5.0} 并且构建日志（包括错误）是：

我可以从这段代码中创建一个.lib，但我需要一个.dll，这很难实现。看起来我错过了一些目标文件或者matlab找不到它，但我不知道该怎么做。

向Ryan Livingston表示赞同这一建议，我将其转变为正式答案

文件lccstub.c（编译为lccstub.obj）不在你的机器上，应该是什么时候。要修复它，您应该为Matlab安装支持的编译器。
