gdb调试C++程序出现Missing separate debuginfos_gdb 程序 missing-优快云博客

文章描述了在使用GNUGDB调试RedHatEnterpriseLinux7程序时遇到Segmentationfault的问题。解决方案是安装缺失的debuginfo包，特别是glibc的相关版本。然而，glibc-2.17-324.el7_9.x86_64无法安装，提示没有可用的debuginfo包。通过编辑/etc/yum.repos.d/CentOS-Debuginfo.repo启用debuginfo仓库并尝试重新安装glibc-2.17-326.el7_9.x86_64的debuginfo包。

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

debuginfo-install glibc-2.17-326.el7_9.x86_64 libgcc-4.8.5-44.el7.x86_64 libstdc++-4.8.5-44.el7.x86_64

然后glibc-2.17-324.el7_9.x86_64总是装不上

打开配置文件 vim /etc/yum.repos.d/CentOS-Debuginfo.repo

# CentOS-Debug.repo

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#

# All debug packages from all the various CentOS-7 releases
# are merged into a single repo, split by BaseArch
#
# Note: packages in the debuginfo repo are currently not signed

把enabled=0改成enabled=1即可
再执行
debuginfo-install glibc-2.17-326.el7_9.x86_64
即可
