[结贴]gdb提示要安装debuginfo-install,可是相关的几个包我都已经装了啊

pppadr

我用的CentOS6。用gcc编了一个程序，没有优化选项，然后用gdb来运行，提示需要安装调试相关的几个库。

1. 
   
2. # gdb a.out
   
3. # gdb a.out

复制代码

可是问题是，这几个包我都已经安装了呀:

1. 
   
2. # yum install glibc-2.12-1.80.el6.i686 libgcc-4.4.6-4.el6.i686 libstdc++-4.4.6-4.el6.i686
   
3. Loaded plugins: fastestmirror, refresh-packagekit, security
   
4. Loading mirror speeds from cached hostfile
   
5. Setting up Install Process
   
6. Package glibc-2.12-1.80.el6.i686 already installed and latest version
   
7. Package libgcc-4.4.6-4.el6.i686 already installed and latest version
   
8. Package libstdc++-4.4.6-4.el6.i686 already installed and latest version
   
9. Nothing to do

不一样，yum install装的版本没有带调试符号debuginfo-install 会安装相应的调试符号。

我尝试运行debug-info install这个命令，得到一堆错误。我的yum源是用的光盘，已经挂载了，yum install是好用的

1. 
   
2. # debuginfo-install glibc-2.12-1.80.el6.i686
   
3. Loaded plugins: fastestmirror, refresh-packagekit
   
4. Loading mirror speeds from cached hostfile
   
5. Loading mirror speeds from cached hostfile
   
6. Could not find debuginfo for main pkg: glibc-2.12-1.80.el6.i686
   
7. Could not find debuginfo pkg for dependency package glibc-2.12-1.80.el6.i686
   
8. ....上面这行的内容会重复输出几十次
   
9. No debuginfo packages available to install
   

复制代码

这到底是怎么回事呢?

    如果/etc/yum.repos.d/CentOS-Debuginfo.repo中enable=0的话改为enable=1，如果还是不行试试yum --nogpgcheck --enablerepo=debug install glibc-debuginfo

pppadr

是这样，我在/etc/yum.repos.d下面现在有两个文件，Base和Debug，分别如下:

1. 
   
2. # ls
   
3. CentOS-Debuginfo.repo  CentOS-Media.repo  keep
   
4. # cat CentOS-Media.repo
   
5. [c6-media]
   
6. name=CentOS-$releasever - Media
   
7. baseurl=file:///media/CentOS_6.3_Final
   
8. gpgcheck=1
   
9. enabled=0
   
10. gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
    
11. # cat CentOS-Debuginfo.repo
    
12. [debug]
    
13. name=CentOS-6 - Debuginfo
    
14. baseurl=file:///media/CentOS_6.3_Final
    
15. gpgcheck=1
    
16. gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6
    
17. enabled=1
    

复制代码

可是不能安装glibc-debuginfo:

1. 
   
2. # yum --nogpgcheck --enablerepo=debug install glibc-debuginfo
   
3. Loaded plugins: fastestmirror, refresh-packagekit, security
   
4. Loading mirror speeds from cached hostfile
   
5. Setting up Install Process
   
6. No package glibc-debuginfo available.
   
7. Error: Nothing to do

    baseurl=file:///media/CentOS_6.3_Final　怎么是指向本地的？你本地自己有源吗？如果没有就改一下：baseurl=http://debuginfo.centos.org/6/$basearch/

哦，是这样，我的系统是在VM里面，挂载了本地的CentOS6.3的安装光盘作为yum源。yum install一般的软件是没有问题的。
要按照你说的，安装debuginfo的话，可以继续用这个光盘作为源吗? 还是一定要指定你给的这个网址作为源才行呢?

谢了

    如果系统是在外网环境中的话那么就使用网络的地址，否则只好用本地了。不能保证本地的源有多全。
