编译 buildroot 错误录

编译 buildroot 错误录

为什么要记录编译过程的错误？

1. 问题定位和诊断
   明确错误来源：编译错误记录提供了错误发生的位置和性质，使工程师能够迅速定位到问题的源头。日志通常会包含文件名、行号以及错误消息，帮助工程师确定出错的代码段。
   历史追踪：记录的错误信息可以帮助追踪错误的历史，从而识别是否是由于最近的代码修改引入的问题。
2. 改进开发效率
   迅速修复：准确的错误记录可以减少调试时间，让开发人员更快地修复问题，而不必手动查找每个可能的错误点。
   减少重复错误：通过分析错误记录，开发人员可以识别出常见的错误模式，从而采取措施避免类似问题的再次出现。
3. 代码质量提高
   代码审查：编译错误记录可以用作代码审查的依据，帮助团队识别和改正代码中的缺陷。
   学习和改进：记录的错误信息为工程师提供了学习的机会，尤其是新手工程师可以通过分析这些错误，了解常见问题及其解决方法，从而提升编程技能。
4. 沟通和协作
   错误记录可以帮助其他人，有效的沟通。如果一个错误难以解决，别人可以将错误日志分享给需要寻求帮助的人。

提示: 编译日志信息提示比较全面，要耐心仔细查看。

1. 内核编译错 错误

错误一

检查 gcc 编译版本。开发环境 22.04，gcc version 11.4.0 符合要求。

gcc --version

根据提示 修改 scripts/dtc/dtc-lexer.lex.c 中错误位置进行屏蔽，或者增加外部变量引用。

-YYLTYPE yylloc;
+extern YYLTYPE yylloc;

builtroot 编译错误

错误一

摘取关键错误信息如下：

2022-07-17T11:31:32 Your PATH contains spaces, TABs, and/or newline (n) characters. 
2022-07-17T11:31:32 This doesn't work. Fix you PATH. 
2022-07-17T11:31:32 make: *** [support/dependencies/dependencies.mk:27: dependencies] Error 1

our PATH contains spaces, TABs, and/or newline (n) characters. 错误提示表明你的操作系统中的环境变量 PATH 包含了空格、制表符或换行符等非法字符，这可能导致编译时出现问题。
错误原因： WSL默认引入 windows 环境参量
修改方法：重置 PATH 环境变量。

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
make

错误二

warning: Python 3 support is currently experimental. YMMV.
Please use Python 2.6 - 2.7 instead.
rv1126/.repo/repo/main.py:19: DeprecationWarning: the imp module is deprecated in favour of importlib and slated for removal in Python 3.12; see the module's documentation for alternative uses

尝试将 repo 脚本解释器，修改 #!/usr/bin/env python 为 #!/usr/bin/env python2，经过测试问题解决。

vi .repo/repo/repo
-#!/usr/bin/env python
-#!/usr/bin/env python2

错误三

2022-07-24T13:34:41 g++: fatal error: Killed signal terminated program cc1plus
compilation terminated.

查阅相关信息后，认为是虚拟机内存不足造成。参照《Android 编译报错记录篇》增加服务器交换分区内存可以解决此问题。

错误四

2022-07-24T09:44:05 g++: fatal error: Killed signal terminated program cc1plus
2022-07-24T09:44:05 compilation terminated.
2022-07-24T09:44:05 make[1]: *** [Makefile:182: cmGeneratorTarget.o] Error 1

与错误三 原因相同，日志体现略有不同。解决方法嘛，就不用细说咯。

错误五

ERROR: Running build_buildroot failed!
ERROR: exit code 1 from line 556:
/usr/bin/time -f "you take %E to build builroot" $COMMON_DIR/mk-buildroot.sh $BOARD_CONFIG

问题原因：buildroot 环境变量发生变迁，无法正常执行。
解决方案：清除当前编译缓存 ./build.sh cleanall，然后重新编译 ./build.sh。

错误六

日志提示 rkisp_parser 命令无法正常执行，手动验证确实存在问题。

/home/1126/buildroot/output/rv1126/host/bin/rkisp_parser
No such file or directory

解决方法：更替 rkisp_parser 为当前系统可执行文件。

Tips

编译错误日志内容很详细。
