缺少单独的debuginfos,请使用:debuginfo-install glibc-2.12-1.47.el6_2.9.i686 libgcc-4.4.6-3.el6.i686 libstdc ++ - 4.4.6-3.el6.i686

Question

CentOS 6.2 + GNU gdb(GDB)红帽企业Linux(7.2-50.el6)

当我用GDB调试一个简单的c ++代码时,我看到了以下警告:

Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.47.el6_2.9.i686 libgcc-4.4.6-3.el6.i686 libstdc++-4.4.6-3.el6.i686

我尝试了以下方法,但没有一个能解决问题:

1. 搜索SO

2. yum install glibc

3. debuginfo-install glibc-2.12-1.47.el6_2.9.i686 libgcc-4.4.6-3.el6.i686 libstdc++-4.4.6-3.el6.i686

事实上,当我逐个安装这些RPM时,我才意识到它们已经安装好了.

[root@localhost Excluded]# rpm -ivh glibc-2.12-1.47.el6_2.9.i686.rpm 
Preparing...                ########################################### [100%]

为什么GDB找不到它？

问题:我是否要担心这个问题？如果没有,如何将其关闭？如果是的话,如何解决？

谢谢

debuginfo-install是命令yum-utils,所以

1. yum install yum-utils
2. debuginfo-install glibc
3. 如果警告仍在那里,编辑/etc/yum.repos.d/CentOS-Debuginfo.repo,设置enabled=1
