尝试执行核心转储分析时缺少库符号

  • 772

我正在尝试分析 systemd 进程的核心转储文件，但由于缺少符号而遇到错误。

有人可以建议需要安装哪些调试符号才能成功分析这些核心转储吗？

    发布版本（--releasever=8.9）很重要，因为当前版本是 8.10，并且dnf将默认使用此版本。

    运行 dnf 列出提供符号的内容

    sudo dnf --releasever=8.9 --enablerepo='*debug*' provides /usr/lib/debug/.build-id/d0/43572678e11cfb56aecb4ec534bc016de8d0d5.debug /usr/lib/debug/.build-id/94/5e15d6b231fc346823186cd70e886dede771ca.debug

Repo        : baseos-debuginfo
Matched from:
Filename    : /usr/lib/debug/.build-id/d0/43572678e11cfb56aecb4ec534bc016de8d0d5.debug

    然后安装所需的包：

    sudo dnf --releasever=8.9 install libuuid-debuginfo-2.32.1-44.el8_9.1.x86_64
