</I>>><i> Hi All,
</I>>><i>
</I>>><i> Could someone kindly tell me that how to install a debug package with

</I>><i>
</I>><i> There is not dependencies between debug packages, in the sense of 'debug
</I>><i> package X need debug package Y to be used'.
</I>><i>
</I>><i>
</I>
Thanks for your explaination.
>><i> For example, I install the firefox-debug-10.0.7-1.mga2.x86_64 package
</I>>><i> for debugging the firefox. While gdb load the firefox core dump file,
</I>>><i> gdb cannot read debugging symbols from other debug packages as they
</I>>><i> are not installed at the same time. Although they are needed for
</I>>><i> debugging.
</I>><i>
</I>><i> I don't know if there an easy way to do it. Usually, tough, the name of the
</I>><i> function where the crash does occurs is enough to tell wich debug package is
</I>><i> needed exactly.
</I>><i>
</I>><i> That could be an interesting urpmi feature, tough, to be able to
</I>><i> automatically install all those packages at once.

Yes. Because while debugging a program in RHEL or Fedora, a command
named 'debuginfo-install' which is provided by yum-utils can be used
to automatically install all needed debug information packages. For
example, to install the debuginfo package of bash:
#debuginfo-install bash
Loaded plugins: fastestmirror, refresh-packagekit, remove-with-leaves
enabling epel-debuginfo
Loading mirror speeds from cached hostfile
* base: mirrors.btte.net
* epel: ftp.riken.jp
* epel-debuginfo: ftp.riken.jp
* extras: mirrors.btte.net
* nux-dextop: mirror.li.nux.ro
* updates: mirrors.163.com
Checking for new repos for mirrors

Is this ok [y/N]:
For developer and Testing Engineer, the easier to obtain full debug
information about a package, the easier to find out defects or bugs.
Besides the debuginfo package, I think the kexec package is important
to generate a vmcore if the kernel panic occurs. I repackage the
kexec-tools of Mandriva for Mageia and currently testing on my laptop.
BTW, the gdb in the mageia2 still cannot tell which debug packages
should be installed while debugging. And it seems that the work-around

does not works...
Should I recompile the latest gdb package on Mageia to make it work?
Many thanks!!
