我目前正在使用Artery在自定义方案中模拟流量。懒惰，我只是在omnetpp.ini文件中更改了所需的sumo-files和launchd.xml以及引用，以便我可以使用run_example目标运行Artery。
到目前为止一切顺利。
Qtenv开始没有问题我得到一个对话，提示我选择ini配置（General，veins，inet或inet_rsu）。每当SimTime运行inet_rsu配置大约140秒时，程序崩溃产生以下错误消息：
CXX=/usr/local/opt/llvm/bin/clang++ \
LDFLAGS+='-L/usr/local/opt/llvm/lib \
-L/usr/local/Cellar/llvm/5.0.1/lib -lclang' \
CPPFLAGS=-I/usr/local/opt/llvm/include \
make myprog
完整的终端输出如下：
opp_run: /home/wiconlab/Car2x/artery-master/src/artery/application
/LocalDynamicMap.cc:24: void artery::LocalDynamicMap::updateAwareness(const CaObject&): Assertion `entry.expiry > omnetpp::simTime() && entry.expiry < omnetpp::simTime() + 2.0' failed
在Debug配置中运行后的Backtrace：

答案 0 :(得分：3)
LocalDynamicMap第24行中的断言尝试确保仅添加最近的CAM。在之前的行中，从截断的generationDeltaTime时间戳重建完整的CAM生成时间戳。也许出现了问题，但如果没有进一步的信息，我几乎无法分辨。您能否提供有关修改的详细信息？这可能有助于重现此错误。
另外，我建议通过调用debug_example目标来使用调试器运行模拟。请确保将CMAKE_BUILD_TYPE设置为＆＃34; Debug＆＃34;启用此目标。当断言失败时，你就有机会详细查看变量：什么是确切的OMNeT ++模拟时间，即＆＃34; print simTime（）。dbl（）＆＃34;用gdb？什么是CAM的一代DeltaTel？什么是重建的tai值？ LocalDynamicMap的计时器（mTimer）的时基（mTimebase）是什么？
附录1：如果您更喜欢图形用户界面，可以使用ccmake或cmake-gui从命令行轻松修改CMake变量。示例：转到您的Artery构建目录（通常简称为＃34; build＆＃34;）并调用＆＃34; ccmake。＆＃34;从那里。在随后打开的命令行界面中，将光标移动到CMAKE_BUILD_TYPE条目，按[Enter]并将此条目修改为＆＃34; Debug＆＃34;。按[c]运行CMake配置阶段，然后按[g]在生成目录中生成更新的Makefile。
