【问题描述】：
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，但我不断收到相同的错误，我找不到解决方案。
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 coder 的应用版本以及命令：codegen -config:dll lbryTest -args {2.0, 5.0}
和构建日志，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，但事实证明这很困难。看起来我缺少一些目标文件或 matlab 找不到它，但我不知道该怎么办。
【问题讨论】：
-
也许你也应该发布你用来生成代码的命令。
-
发布整个构建日志也可能会有所帮助，包括编译 C 文件的行。是在
codegen目录下生成的文件lccstub.obj，默认codegen\dll\lbryTest？ -
还要检查一下，codegen 目录的完整路径是否包含任何“特殊”字符？众所周知，诸如 $、&、非英文字符之类的东西会导致 gmake 出现问题。在这种情况下，联系MathWorks technical support 可能会有所帮助。
-
谢谢。由于某种原因，文件
lccstub.c似乎没有被编译为生成lccstub.obj。为了快速解决问题，您可以考虑安装另一个 supported compiler。 This article 描述了安装和使用免费提供的 Microsoft Windows SDK 7.1 以与 MATLAB 一起使用。 -
lcstub.c 应该随 MATLAB 一起提供。但我仍然建议尝试使用 Windows SDK 来构建共享库。
