前言

CommonAPI是本次学习的终极目的，vsomeip学习是前提

---

一、Ubuntu 20.04安装

1.Recommended Ubuntu system OS is 20.04, link is:
https://releases.ubuntu.com/20.04/ubuntu-20.04.6-desktop-amd64.iso.torrent

2.After download, the system OS file is .ISO format, which can’t be used for booting from USB, we should use anther tool to convert it. The tool name is one free tool rufus-4.3.exe.
https://github.com/pbatard/rufus/releases/download/v4.3/rufus-4.3.exe

3.Install Ubuntu system OS to PC.（略）

4.Modify the source.list ahead, tsinghua server is prefer and aliyun server has some bug.

二、vsomeip 源码下载

1.add your public key to gitee.com, if your PC is a new one and need below command to generate public key.

will@will-OptiPlex-7050:~/work$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/will/.ssh/id_rsa): 
Created directory '/home/will/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/will/.ssh/id_rsa
Your public key has been saved in /home/will/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:k4hdnffthtB0n3c96lnH/Thcex9hN5tFwWSHp80jgAc will@will-OptiPlex-7050
The key's randomart image is:
+---[RSA 3072]----+
|         Eo   o=.|
|         o +  o.+|
|        . + o .=o|

|    . o S   . +*X|s

|             o.*B|
|            . =+=|
|             o..=|
+----[SHA256]-----+
will@will-OptiPlex-7050:~/work$ cd ~/.ssh
will@will-OptiPlex-7050:~/.ssh$ cat id_rsa.pub

2.add the public key gitee.com to allow us download source code conveniently.

3. download vsomeip source code from gitee.com

will@will-OptiPlex-7050:~/work$ git clone git@gitee.com:mirrors/vsomeip.git

will@will-OptiPlex-7050:~/work$

4. Several libs need installed ahead

will@will-OptiPlex-7050:~/work$ sudo apt-get install libboost-system-dev libboost-thread-dev libboost-log-dev
will@will-OptiPlex-7050:~/work$ sudo apt-get install asciidoc source-highlight doxygen graphviz
will@will-OptiPlex-7050:~/work$ sudo apt-get install gcc g++ make

5. Build vsomeip source code using follow commands

will@will-OptiPlex-7050:~/work/vsomeip$ mkdir build
will@will-OptiPlex-7050:~/work/vsomeip$ cd build
will@will-OptiPlex-7050:~/work/vsomeip/build$ cmake ..

Command 'cmake' not found, but can be installed with:

sudo snap install cmake  # version 3.27.7, or
sudo apt  install cmake  # version 3.16.3-1ubuntu1.20.04.1

See 'snap info cmake' for additional versions.

will@will-OptiPlex-7050:~/work/vsomeip/build$ sudo apt install cmake=3.16.3-1ubuntu1.20.04.1
will@will-OptiPlex-7050:~/work/vsomeip/build$ cmake ..
will@will-OptiPlex-7050:~/work/vsomeip/build$ make
will@will-OptiPlex-7050:~/work/vsomeip/build$ sudo make install

三、vsomeip example source code build

will@will-OptiPlex-7050:~/work/vsomeip/build$ cd ..
will@will-OptiPlex-7050:~/work/vsomeip$ cd examples/hello_world/
will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world$ mkdir build
will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world$ cd build/
will@will-OptiPlex-7050:~/work/vsomeip/examples/hello_world/build$ cmake ..

总结

Ubuntu 版本太多，但是网上大多资源都是基于20.04的，建议用这个版本。
Source list建议用清华的镜像，阿里云的会有问题，光解决错误就麻烦大了。
vsomeip编译没什么难的，但是那些libraries都需要安装正确先。
