Foreword

Verify that vsomeip can communicate between Host Linux and Guest Linux in LXC.

  1. Verify that vsomeip comes with helloworld routine
  2. Create helloworld Service and client configuration files
  3. Verify vsomeip communication in dual-machine situation
  4. Verify vsomeip communication between LXC internal and external systems

1. Verify that vsomeip comes with helloworld routine

The unicast address needs to be changed to 127.0.0.1, which means it is running inside the machine.

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

According to the instructions in the readme, directly copy the execution command to run. What needs to be explained is that
1. The configuration of vsomeip requires importing your own JSON file, otherwise the default configuration that comes with the system will be used;
2. During the first execution, you will encounter the problem that the configuration module cannot be loaded. This can be solved by executing sudo ldconfig.

1. Run the server APP first

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

The log will be printed as follows

2. Run the client APP again

Run vsompip client side:
will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world/build$ VSOMEIP_CONFIGURATION=../helloworld-local.json VSOMEIP_APPLICATION_NAME=hello_world_client ./hello_world_client

The corresponding log is as follows

2023-11-01 15:53:15.641830 [info] local_uds_client_endpoint_impl::receive_cbk Error: Operation canceled

There are some errors in the log backend, “local_uds_client_endpoint_impl::receive_cbk Error: Operation canceled”. After searching for a long time, I still can’t find the reason, but it should not affect the verification of vsomeip.

2. Create helloworld Service and client configuration files

1. Modify code

  1. hello_world_service.hpp
bool init(){<!-- -->
        
        setenv("VSOMEIP_CONFIGURATION", "../helloworld-service.json", 1);
        setenv("VSOMEIP_APPLICATION_NAME", "hello_world_service", 1);
  1. hello_world_client.hpp
bool init(){<!-- -->
        
        setenv("VSOMEIP_CONFIGURATION", "../helloworld-client.json", 1);
        setenv("VSOMEIP_APPLICATION_NAME", "hello_world_client", 1);

2. Run the test APP

4. Rebuild vsomeip source code and the run service side in advanced
will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world/build$ make clean
will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world/build$ make

5. Run client side app.

Summary

To learn vsomeip, I can only rely on myself to collect some information on the Internet. Since the configuration instructions are not detailed enough, or it is difficult to explain my confusion, I spent a lot of time researching and trying. Due to limited space, I decided to divide the learning process into two articles to share with everyone.
