kodi crash, and gdb not found

kodi crash, and gdb not found

[Marco van Hulten]

Hi,

I have `kodi' and `gdb' installed.  When I start kodi, it crashes:

https://paste.debian.net/996313/

An excerpt of the `kodi' output:
> gdb not installed, can't get stack trace.

but I installed gdb, under the same user:

    kodi@watson ~$ gdb --version | head -1
    GNU gdb (GDB) 8.0.1

Interesting, `man gdb` does not gives an empty or unreadable man page:
at the bottom of the terminal is:
> Manual page gdb(1) line ?/? (END) (press h for help or q to quit)

I have never before tried (to let a program) use gdb on GuixSD.

Last Sunday, the program `kodi' worked fine.  Shortly after that
(according to lastlog(8) the same day), I did a package upgrade, but
did not test kodi hereafter (according to `history`).  Today, I tested
kodi and it crashes.  I upgraded packages, but then it still crashes.

Can you try rolling back to the generation that worked, to verify that
it's not something in your environment that has changed?  Maybe also try
to temporarily move away the ".kodi" folder in the users home directory.

I'm currently testing the latest git snapshot of Kodi regardless, the
alpha version in Guix is pretty old already.  Originally Kodi 18 was
slated for July, but the release was pushed back to January[0], so the
version in Guix is probably pretty buggy.

Removing ~/.kodi/ did not solve the issue.

Rolling back sufficiently far did help.  My generations:

4 — kodi 18.0-ALPHA1 Git:20171106-nogitfound — works
5 — kodi 18.0-ALPHA1 Git:20171113-nogitfound — crashes

Fantastic feature this rolling back!

Sidenote: I see that the guix-profile symlink in
/var/guix/profiles/per-user/*/ is absolute; why no relative links?

I installed GuixSD 0.13.0.  Hereafter, I have done a `guix pull` and
`guix package -u`, which resulted recently in

9 — kodi 18.0-ALPHA1 Git:20171113-nogitfound — crashes

That's six days ago; that's not that old, right?

It's pretty nice :-)

I assume "18.0-ALPHA1" here is actually "18.0_alpha-6-f22d62d".

I have updated the snapshot in Guix to point to the latest upstream
commit as of today, can you try updating to it and see if that works for
you?  It starts here on an up-to-date profile, at least.

I did this, but it did not solve the issue:

$ kodi --version
18.0-ALPHA1 Git:20171120-nogitfound Media Center Kodi
Copyright (C) 2005-2013 Team Kodi - http://kodi.tv
$ kodi

Crash report available at /home/kodi/kodi_crashlog-20171121_051607.log

[1]: https://paste.debian.net/996798/

I installed libvdpau-1.1.1, but that did not resolve the problem either.

It seems that these things are not found in one way or another:

- gdb (see [1])
- git (`kodi --version`)
- vdpau (`kodi`)

Could there be a common cause?

Hi,

Marco van Hulten <marco@hulten.org> skribis:

> $ kodi

Guix’s ‘mesa’ package does not provide this specific shared object under
lib/vdpau, so there might be some interference with the host distro.

What happens if you run:

  guix environment --pure --ad-hoc kodi -- kodi

or:

  guix environment -C --ad-hoc kodi -- kodi

?

That looks bad.

Do let me know if you need the backtrace and/or memory map and/or the
crash log of the Kodi crash.

I am installed GuixSD 0.13.0, and upgraded it (pull & package -u).

I wonder why this only started happening recently.  Can you post the
output of `guix package -l` so we can see what changed between the
working and non-working profile?

Which graphics hardware are you on?  Does video acceleration work in
other programs such as "mpv" or IceCat?

`mplayer` worked fine, the video played fluently.  I couldn't find so
quickly a youtube-like website that is out of the box compatible with
IceCat.  I may try tonight (CEST) if it is useful.

Hi,

Concerning my kodi crash happening on my system but not on other's [1],
maybe by system got broken and I should reinstall.

I understand that the state of a GuixSD installation is defined by one's
`config.scm`.  Thus I can very easily reproduce an exact copy of the
functional system.

However, there are also packages installed per user.  What would
define, excluding data files in the home directories, the complete
state of a system, including both the core OS and packages (as
available per user), if there such a thing in GuixSD?

Indeed.  This property makes it essentially useless to reinstall, since
the system is stateless (or “mostly” stateless.)

If you use declarative profiles with ‘guix package -m’, then all you
need is to keep both the system config.scm and the user profile
manifests.

Otherwise there’s no fully automated way to capture the whole system
state.  It would be a useful addition!

Besides, if your concern is to allow others to reproduce the Kodi crash
you experienced, my suggestions would be to try and see if you can
reproduce it in a VM created with ‘guix system vm’.  If you can do that,
then others will be able to reproduce it as well and to investigate.

HTH!

Ludo’.
