Missing separate debuginfos

I am debugging a coredump file from the production environment(two environment, not the same), I input "gdb [programe name] core.xxx then bt" but it hint like the title and pic below: enter image description here There are question masks at the top of the stack and I can't find where the Segmentation fault generated Kernel Version: enter image description here Linux Version: enter image description here

System compiled from executable file：enter image description here (Note :Source code and executable program are not in the same system)

I want to find a way to know where did the segment error occur, I'd appreciate it if you could help me !

I have installed some missing rpm libraries according to the prompts but still not work： glibc-debuginfo-2.17-326.el7_9.x86_64.rpm libgcc-4.8.5-44.el7.i686.rpm ncurses-libs-5.9-14.20130511.el7_4.i686.rpm libstdc++-4.8.5-44.el7.i686.rpm kernel-debug-debuginfo-3.10.0-1160.el7.x86_64.rpm kernel-debuginfo-common-x86_64-3.10.0-1160.el7.x86_64.rpm

Solution

  • My OS CentOS 7.9

    Missing separate debuginfos, use: debuginfo-install glibc-2.17-326.el7_9.x86_64 libconfig-1.4.9-5.el7.x86_64 libgcc-4.8.5-44.el7.x86_64 libstdc++-4.8.5-44.el7.x86_64

    1. You need to modify the enable=1 of the /etc/yum.repos.d/CentOS-Debuginfo.repo (CentOS 7) or the /etc/yum.repos.d/CentOS-Stream-Debuginfo.repo(CentOS 8)
    2. Use sudo yum install glibc to install
    3. yum install yum-utils
    4. Use yum debuginfo-install glibc-2.17-326.el7_9.x86_64 to install.

    Hope this help.
