Missing separate debuginfos

Missing separate debuginfos

[Mahmood Naderan]

Hi
What is the meaning of this message I see in gdb?

Loaded symbols for /usr/lib64/libstdc++.so.6
0x00000037d6c0f3cb in raise () from /lib64/libpthread.so.0
Missing separate debuginfos, use: debuginfo-install bzip2-libs-1.0.5-7.el6_0.x86_64 compat-libstdc++-33-3.2.3-69.el6.x86_64 glibc-2.12-1.80.el6_3.5.x86_64 libICE-1.0.6-1.el6.x86_64 libSM-1.1.0-7.1.el6.x86_64 libX11-1.3-2.el6.x86_64 libXau-1.0.5-1.el6.x86_64 libXext-1.1-3.el6.x86_64 libXpm-3.5.8-2.el6.x86_64 libgcc-4.4.6-4.el6.x86_64 libstdc++-4.4.6-4.el6.x86_64 libuuid-2.17.2-12.7.el6.x86_64 libxcb-1.5-1.el6.x86_64 zlib-1.2.3-27.el6.x86_64


There are some pages on the web but I didn't find a clear answer. Indeed those packages are installed on my system. Is tat a critical message?

No, it is not critical.

It means you don't have the debug information for these specific
packages/versions.  Unless you want to debug them, you don't really need
to worry.  If you ever want to debug them, you can run the command
suggested.

A bit off topic for this list, but I've thought before that
message isn't as clear as it could be.

> Missing separate debuginfos, use: debuginfo-install

I think we could drop "separate", as it is an implementation
detail that shouldn't matter to the user.  "debuginfos" being
plural reads a bit weird to me.  I think this would be a bit
clearer:

Debug info for packages used by the program missing. Install with: debuginfo-install

But of course that may well just be me.

Maybe be even wordier, like

    Some debug info for packages used by the program is missing.  You can
    install this with:

       debuginfo-install package-1 \
           package-2 \
           package-3

    Once the packages are installed, you can use them in the current gdb
    with:

       nosharedlibrary
       sharedlibrary .*

    Future invocations of gdb will pick them up automatically.

Of course then you get into pagination, especially if you have a ton of
uninstalled debug packages.

We could trim this down the second time it is printed.

Maybe it would be nice if debuginfo-install were a gdb command.
Then it could do the sharedlibrary dance for the user, without needing
nosharedlibrary.


The "nosharedlibrary" thing is also hard to figure out.
See http://sourceware.org/bugzilla/show_bug.cgi?id=12794
and http://sourceware.org/bugzilla/show_bug.cgi?id=14479

This could definitely use an enhancement.

It should be a question installing it on its own if answered 'y', according to
some feedback in the meantime.

And it should run some PackageKit or even apt-get etc. depending on the OS.
