在 Windows 中使用 open62541 构建一个简单的服务器

【问题描述】：

我正在尝试通过参考page 提供的文档来使用 open62541 构建服务器。

通过参考webpage，我可以生成 open62541.c 和 open62541.h 文件。 如前所述，我使用 CMake 和 VisualStudio 生成了这些文件。当我尝试编译 myServer.c 文件时，出现以下错误。

大多数thr错误描述未定义某些变量。我发现在open62541.h或open62541.c文件中未定义UA_SOCKET，但在文档中写到这两个文件足以构建服务器文件.

有人成功编译服务器文件吗？谢谢。

错误
