Hi Guix,

Dino segfaults.  I tried doing "guix install dino" again; it didn't
help.

I don't know if this is any help, but I just tried it in a Guix shell 
and it seems to start OK on my machine (Dell desktop, Intel graphics, 
X11, standard GUIX OS kernel). So, it's probably your machine / setup. 
I'm not the packager or even a user, though, I just gave it a try. 
Hopefully someone else will be more helpful.

Best Regards,

G.

Hi Caleb

while I am also neither user nor packager of Dino, I have a suggestion
— you'll perhaps learn more when you try running Dino in a virgin
environment inside a container?  You could try this command

guix shell --container --no-cwd --network \
    --share=/tmp --expose="$HOME"/.Xauthority \
    dino bash \
    -- bash -c "DISPLAY=:0 dino"

Also, you did a `guix pull` sometime recently to get up-to-date
packages, right?

Oh, sorry.  I pressed r instead of R when replying in Emacs.  We should
be back on the mailing list now.

Ahh, I forgot we also need to pass the XAUTHORITY variable to the
container.  How about this?

guix shell --container --no-cwd --network \
    --share=/tmp/.X11-unix --expose="$XAUTHORITY" \
    dino bash \
    -- bash -c "DISPLAY='$DISPLAY' XAUTHORITY='$XAUTHORITY' dino"

It launches!  But of course, it has no knowledge of my configuration,
and asks to set up an account.

Hi Caleb,

You're making progress.  Outside the container, does `dino --help' work? 
You can make the program print diagnostic messages. Option 
`--gst-debug-level=LEVEL' (where LEVEL=0..9) can print *a lot* of 
diagnostics for GStreamer.  Have you tried it? It may help you find the 
point at which the program segfaults.

Best Regards,

G.

Just for the record: I'm a dino user and it works well for me. The
version is 0.4.3. I'm not sure which info I can provide to compare our
configurations.

Re: Dino segfaults

Hi Caleb,

An application segfaulting at such an early stage got me curious. Now I 
see it's a Vala application, so it does quite some initialization before 
parsing the command line arguments.  Anyway, following the link at 
`which dino' shows that `dino' is a shell script.  It sets some 
variables then calls `.dino-real', which is the actual binary.  Does 
executing `.dino-real --version' segfault too?

Best Regards,

G.

What about to run it as `strace .dino-real --version`? I expect it
complains on something before a segfault.

It outputs a lot of stuff.  .dino-real --version outputs a version
number.  I wonder if "dino" will work?

It works!

I did a system upgrade yesterday.  Dino seems to be running now.

Interesting — I wonder whether it is thanks to the update or to logging
out and in again.

Anyway, good for you :)

Happy chatting

Re: Dino segfaults

[Georgios Athanasiou]

Hi Caleb,

You can run Valgrind on it, maybe it'll show where the crash happens:

     guix shell dino valgrind

     valgrind .dino-real --version

Best Regards,

G.
