如果运行此代码，为什么会得到错误代码139? [英] Why I get an error code 139 if I run this code?

问题描述

我想知道为什么可以构建该项目，但是RSU收到该消息后，我会收到一条错误139.即使我尝试通过删除插入在onData函数中的代码来解决并再次运行该项目，不起作用.

I would like to know why I can build this project, but as soon as RSU receives the message I get an error 139. Even if I try to solve by removing the code inserted in onData function and run the project again, still doesn't work.

TraCIScenarioManager* manager;
TraCICommandInterface* traci;

TraCIDemoRSU11p.cc

void TraCIDemoRSU11p::initialize(int stage) 
{
    BaseWaveApplLayer::initialize(stage);
    if (stage == 0) {
        manager = TraCIScenarioManagerAccess().get();
        traci = manager->getCommandInterface();
        traci->trafficlight("0").setProgram("tram_is_not_passing");
    }
}


void TraCIDemoRSU11p::onData(WaveShortMessage* wsm) 
{
    traci->trafficlight("0").setProgram("tram_is_passing");
}

静脉版本是4.4，而omnet ++版本是5.我认为问题可能出在初始化函数中是如何获得traci接口的，请问谁能解释两个模块如何同时使用traci接口?

veins version is 4.4 and omnet++ version is 5. I think the problem might be how I got traci interface in the initialize function, can anyone please explain how two modules use traci interface at the same time?

根据要求，我要向问题添加更多信息.

As requested I am adding more information to the question.

推荐答案

据我所知，OMNeT ++的错误代码从128开始，然后添加了正常的系统错误代码.这意味着139 = 128 + 11和11是分段错误的错误代码.

As far as I know, OMNeT++ starts at 128 with its error codes and than adds the normal system error codes. This means that 139 = 128 + 11 and 11 is the error code for a segmentation fault.

因此，似乎您正在尝试使用未分配或不允许使用的内存空间.您应该使用./memcheck与Valgrind进行模拟，以查明是否存在内存泄漏.

Hence, it seems you are trying to use memory space which is not allocated or you are not allowed to use. You should run you simulation with Valgrind using ./memcheck to find out whether you have memory leaks.

编辑:在Veins 4.7.1之后，一个新的运行脚本是介绍.现在，您可以使用./run -t memcheck与Valgrind一起运行仿真.

EDIT: After Veins 4.7.1 a new run script was introduced. Now you can run your simulation with Valgrind using ./run -t memcheck.
