【vsomeip】如何让vsomeip在双系统运行起来----(一)

---

前言

验证vsomeip可以在Host Linux和LXC 里面的Guest Linux之间进行通信。

1. 验证vsomeip自带helloworld例程
2. 创建helloworld的Service和client的配置文件
3. 验证双机情况下vsomeip通信
4. 验证LXC 内外系统的vsomeip通信

一、验证vsomeip自带helloworld例程

{
   
    "unicast":"127.0.0.1",
    "logging":
    {
   
        "level":"debug",
        "console":"true"
    },

    "applications":
    [
        {
   
            "name":"hello_world_service",
            "id":"0x4444"
        },

        {
   
            "name":"hello_world_client",
            "id":"0x5555"
        }
    ],

    "services":
    [
        {
   
            "service":"0x1111",
            "instance":"0x2222",
            "unreliable":"30509"
        }
    ],

    "routing":"hello_world_service",
    "service-discovery":
    {
   
        "enable":"false"
    }
}

unicast的地址要更换成127.0.0.1，说明是在本机内部运行。

will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world/build$ VSOMEIP_CONFIGURATION=../helloworld-local.json \
> VSOMEIP_APPLICATION_NAME=hello_world_client \
> ./hello_world_client
1 Configuration module could not be loaded!


Error fix:
will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world/build$ sudo ldconfig

按照readme的说明，直接copy执行命令来运行，要说明的是
1.vsomeip的配置需要import自己的JSON文件，否则会用到系统自带的default配置；
2.第一执行的时候会遇到配置模块无法加载的问题，执行一下 sudo ldconfig就能解决

1. 先运行服务端的APP

Run vsompip server side first:
will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world/build$ VSOMEIP_CONFIGURATION=../helloworld-local.json \
> VSOMEIP_APPLICATION_NAME=hello_world_service \
> ./hello_world_service

log会有 如下打印
