OMNET ++无法加载图像

Question

我是OMNET ++的新手，但是我为下面的错误感到疯狂，由于该错误，我无法根据该教程运行我的tic-toc模拟...我搜索了google，但没有其他人同样的问题。 错误消息是：

我以为我的omnet ++安装可能未完成，但是我尝试从官方页面重新安装OMNET ++，并且我最近更新了QT，但无法正常工作。 QT可以独立运行。错误代码所需的图像在目录中不存在，但是我没有在代码中调用它们，简单的tic-toc怎么需要这些图像？ 我现在应该怎么办？ 这个家伙有同样的问题，但仍然没有解决... unsolved google group problem

Answer 1

我通过在运行配置中将extension Shape { func modified() -> some View { self .foregroundColor(Color.secondary.opacity(0.5)) } } // Usage example struct ContentView: View { var body: some View { VStack { Rectangle().modified() Capsule().modified() } } } 明确设置为与omnet ++捆绑在一起的qt（YourOmnetppDirectory / tools / macosx / plugins /）来解决此问题。适用于macOS。

Answer 2

之所以发生这种情况，是因为与OMNeT ++捆绑在一起的QT安装找不到它的插件，因此无法在模拟器启动时加载默认的OMNeT ++映像。确保已正确遵循安装指南。捆绑的QT库是在OMNeT ++配置过程中设置的（即在您运行./configure时）。此时，configure脚本会自动设置插件的位置。简而言之，请确保：

从主目录中提取tgz文件

$ . setenv
$ ./configure
$ make -j=8 
$ cd samples/aloha
$ ./aloha

尝试在此处运行示例以查看Qtenv是否正常工作。

另一种解决方法：使用Tkenv（这是基于Tk的旧环境）。即通过以下方式开始仿真：

$ ./aloha -u Tkenv
