您好社区我想使用 open62541 lib 为 OPC UA 服务器编写 UI。输入关闭软件应该读取文本文件并将数据通过服务器投射到已经可用的客户端。
卡在需要编译 dll 文件以便在 windows 窗体项目中进一步使用它的阶段。
有一些信息提到 Davy Triponney 使用 Visual C++ 2013 https://github.com/open62541/open62541/wiki/Using-open62541-from-C%23编译它
但我对 VS 2017 没有运气。
我的进步顺序是:
- 已经从https://open62541.org/下载了 .h 和 .c windows 64 位文件
- 创建动态链接库(DLL)项目。
- 将.h和.c文件附加到项目中,选择64编译器:
在构建时收到很多警告和错误:

问题是我如何使用 Visual Studio 2017 编译 open62541 c 代码 dll 文件以在 Windows 窗体 C# 应用程序中将其用作服务器?
