ubuntu14.04编译yocto源码环境配置篇

ubuntu 14.04 编译yocto源码

1. 环境安装

1. ubuntu 14.04

2. yocto依赖工具链

   sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping

3. 源码已经就位

   ./makall

2. 错误记录

2.1 bash or dash

在kernel编译的时候提示no such arch&＃xff1a;

这里就是shell脚本语言在做字符串匹配&＃xff0c;而且同样的code在服务器是编译通过的&＃xff0c;所以这里主要怀疑&＃xff1a;

1. gcc的lib库是否没有安装&＃xff1b;
2. sh是否没有安装&＃xff1b;

经确认主机上与服务器上sh有差异&＃xff0c;主机默认安装为dash&＃xff0c;替换后此错误通过&＃xff1a;

sudo dpkg-reconfigure dash&＃xff0c;选择no

2.2 JDK 1.8 安装

在编译到service阶段的时候出现编译错误&＃xff0c;提示语JDK相关&＃xff0c;在安装openjdk 1.8后可以正常编译通过&＃xff0c;这里记录openjdk 1.8的安装过程&＃xff1a;

1. 替换源&＃xff1a;

   1. 由于ubuntu中默认没有支持openjdk&＃xff0c;所以这里需要在source.list中加入&＃xff1b;
   2. ubuntu官网毕竟是外网&＃xff0c;访问如同龟速&＃xff0c;这里替换为aliyun的镜像网站&＃xff1b;

   sudo cp sources.list sources.list.bak
   sudo vim /etc/apt/sources.list

   具体内容&＃xff1a;

2. 更新并安装jdk

   sudo apt-get install update
   sudo apt install openjdk-8-jre-headless
   sudo apt install openjdk-8-jre
   sudo apt install openjdk-8-jdk

3. 验证&＃xff1a;

   java -version

3.2.3 libinput 编译meson失败

1. 出错环节&＃xff1a;

   gcc /code/20201016sumo/build/tmp/work/aarch64-poky-linux/libinput/1.9.4-r0/build/meson-private/sanitycheckc.c -o /code/20201016sumo/build/tmp/work/aarch64-poky-linux/libinput/1.9.4-r0/build/meson-private/sanitycheckc.exe

2. 错误信息&＃xff1a;

   /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.8/…/…/…/x86_64-linux-gnu/crti.o: unrecognized relocation (0x2a) in section &＃96;.init’
   /usr/bin/ld: final link failed: Bad value
   collect2: error: ld returned 1 exit status

   1. 这里提示在链接crti.o时出错&＃xff0c;地址不识别&＃xff0c;这里多半认为是版本问题
   2. 将已经编译过得环境中crti.o替换到主机中&＃xff0c;编译通过
   3. 说明是gnu lib库有差异
      1. gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3)
      2. gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.4)

3. 处理方案&＃xff1a;

   1. 在gnu lib中替换crti.o

3.2.4 打包ext4 image错误

1. 错误提示&＃xff1a;

   make_ext4fs执行时有库找不到

2. ldd 命令查看链接库&＃xff1a;

   20201016sumo/src/build/tools$ ldd make_ext4fs

   linux-gate.so.1 &＃61;> (0xf773b000)
   libstdc&＃43;&＃43;.so.6 &＃61;> not found

3. file命令查看make_ext4fs

   make_ext4fs: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, not stripped

   结合错误信息来看&＃xff0c;默认这个库安装时64bit的&＃xff0c;所以需要安装对应32bit的libstdc&＃43;&＃43;.so.6

4. 处理&＃xff1a;

   sudo apt-get install lib32stdc&＃43;&＃43;6

   搞定收工

3.3 总结

错误原因大多为&＃xff08;环境配置&＃xff09;&＃xff1a;

1. 缺少某些环境或者库&＃xff0c;例如JDK等
2. 某些环境的版本与code依赖版本不匹配&＃xff0c;例如openssl、libgnu等等
3. 某些工具配置不对&＃xff0c;例如bash等

在新的环境编译新的系统&＃xff0c;总会遇到各式各样的环境问题&＃xff0c;整体思路就是确认出错步骤&＃xff0c;单步执行打印提示&＃xff0c;逐步check即可
