我正在omnet ++和静脉（v2.0-rc1）下进行网络仿真，为此目的，我对4个场景进行了实验，两个场景都有20次重复。
在第3和第4种场景的仿真过程中，我遇到了一些错误（我想这是内存分配错误），它们共享一个共同的功能（ack）。
对于相关的模拟，它可以正常启动并执行几次重复，但是此后失败（例如，它在第四种情况的第五次重复中失败），这是输出：

为了调试错误，我在此命令中使用了valgrind：
valgrind --tool=memecheck ./veins (with veins is the current binary of my simulation)
但似乎所有返回的错误都与我的代码无关（因为我对以前工作正常的代码做了同样的操作，并且得到相同的输出）
编辑这里是Valgrind的输出

RUNTIME ERROR. A cRuntimeError exception is about to be thrown, and you requested (by setting debug-on-errors=true in the ini file) that errors abort execution and break into the debugger.
You should now probably be running the simulation under gdb or another debugger. The simulation kernel will now raise a SIGABRT signal which will get you into the debugger. If you are not running under a debugger, you can still use the core dump for post-mortem debugging. Once in the debugger, view the call stack (in gdb: "bt" command) to see the context of the runtime error.
<!> Error in module (cCompoundModule) scenario (id=1) during network setup: Class "ObstacleControl" 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().
TRAPPING on the exception above, due to a debug-on-errors=true configuration option. Is your debugger ready?

我也尝试激活转储文件并使用gdb对其进行分析，得到以下输出：

有人可以帮助您识别错误吗？
注意：错误的代码引入了一个特定的数据结构，它是一个std :: map，其中包含一个std :: set作为值
最佳答案
您将需要使用相同的命令行参数启动仿真的调试（或内存检查）运行；否则，将不会加载任何模型库，并且模拟将不会执行。
请注意，与如何启动模拟的调试或内存检查运行无关，您应确保在Cmdenv（命令行环境）而不是Tkenv中运行它。不仅可以更快地执行模拟，还可以确保所有警告都与模拟模型相关，而不是与GUI和各种GUI库相关。您可以通过将-u Cmdenv附加到命令行，或者（在IDE中）通过编辑模拟的运行配置并选择“用户界面：命令行”来实现。
如果从命令行运行模拟，只需在通常执行opp_run或模拟二进制文件（例如./veins）的前面加上gdb --args（运行调试器）或valgrind --tool=memcheck（运行内存）即可检查器）。命令行示例可能是/usr/bin/valgrind --tool=memcheck opp_run -l../../src/veins -n../../src/veins;. -u Cmdenv（其中添加了粗体文本）。
如果要从命令行运行模拟，但是当前正在使用OMNeT ++ IDE，则可以快速检查正在使用哪些命令行参数来运行模拟。运行模拟时，请在控制台视图中观察输出。输出可能以OMNeT++ Discrete Event Simulation开头。在输出的开始附近，您还会发现以$开头的两行。这些是IDE用于运行模拟的确切命令。
如果要从OMNeT ++ IDE运行模拟，请注意，它还具有内置功能，可通过调试器或内存检查器运行模拟。要在其中任一模式下运行模拟，请右键单击.ini文件（例如，模拟的omnetpp.ini，然后选择Debug As（对于gdb）或Profile As（对于valgrind），然后选择OMNeT ++ Simulation。可以在新的Valgrind视图中找到valgrind的输出。
