i want to import openflow extension into veins, when i run openflow simulation it works correctly, but when start veins simulation I receive the error:我想将 openflow 扩展导入静脉，当我运行 openflow 模拟时它可以正常工作，但是当开始静脉模拟时我收到错误：

Class "Flow_Table" not found -- perhaps its code was not linked in, or the class wasn't registered with Register_Class(), or in the case of modules and channels, with Define_Module()/Define_Channel().

Your simulation will need to load the libraries (on Windows: .dll files, on Linux: .so files) which contain the simulation modules you are using.您的模拟将需要加载包含您正在使用的模拟模块的库（在 Windows 上： .dll文件，在 Linux 上： .so文件）。

Check the command line used to run your simulation (likely it starts with opp_run ).检查用于运行模拟的命令行（可能以opp_run ）。 If it does not contain a -l switch for the OpenFlow simulation library, you will not be able to create its modules in your simulation.如果它不包含 OpenFlow 模拟库的-l开关，您将无法在模拟中创建其模块。

If you use the OMNeT++ IDE to start your simulation, look at the very top of the Console window to see which command line parameters were used.如果您使用 OMNeT++ IDE 开始模拟，请查看控制台窗口的最顶部以查看使用了哪些命令行参数。 For example, in the following screenshot you can see that only -l ../../src/veins is specified;例如，在下面的屏幕截图中，您可以看到仅指定了-l ../../src/veins ； thus, only modules from libveins.so are loaded.因此，只加载来自libveins.so模块。
