使用独立文件在omnet ++中运行模拟

我想在没有omnet ++的机器上运行我的模拟。有什么方法可以做到吗? 是否有可能以自给自足的方式构建我的项目?

OMNET项目需要opp_run文件(omnet-x.x / bin / opp_run)。基本上,opp_run允许启动链接为共享库的模拟模型。您可以使用

运行模拟
opp_run -r 0 -u Cmdenv -c yourConfigName -n . -l yourProgram params.ini

-r <runnumber> allows you to select runs
-u Cmdenv tells omnetpp to run under Cmdenv (command-line environment)
-c <configname> option is used to select a configuration
-n option is used to specify the NED path
-l option is used to load additional shared libraries

opp_run需要许多共享库才能正常运行。在Linux中,您可以使用ldd列出opp_run所需的所有共享库。例如在我的Ubuntu 14机器上:

enter image description here

正如您所看到的,opp_run需要许多共享库,您需要将它们全部安装在目标计算机上。

我也在Linux服务器(Ubuntu 14 Server)上运行OMNET模拟。但是我已经在我的主文件夹上安装了OMNET(不需要sudo访问)并且可以使用上面的命令运行模拟(假设你已经安装了所有必需的库)。检查OMNET安装guide以检查系统上需要哪些软件包。

您可以通过使用静态库选项编译OMNeT++来避免对原生liboppenvird.so库的依赖(例如liboppsimd.soOMNeT++等)。为此,请从主configure.user目录中打开OMNeT++并设置:
SHARED_LIBS=no
然后重建您的OMNeT ++(make clean./configuremake)。接下来重建您的项目。 tictoc示例:

cd samples/tictoc
opp_makemake -f --deep
make clean && make

然后ldd tictoc会显示:

此外,如果您不需要图形界面,则只能为命令行模式构建项目。它减少了依赖项的数量。为此,请使用命令:
opp_makemake -f --deep -u Cmdenv
(或使用OMNeT++中的项目属性设置它)。
