Arch Linux User Repository

@jshholland Can you try a clean build? I can no longer reproduce the problem on 5.2.1, it's all good on my end.

$ makepkg --version
makepkg (pacman) 5.2.1

According to the pacman NEWS file, the gzip bug was fixed in 5.2.0, but I'm still seeing this same bug.

@UndeadKernel: Ah, figured it out! Eli Schwartz confirmed on IRC that it's a recently-introduced upstream bug: https://git.archlinux.org/pacman.git/commit/?id=99c5809bbf01725829ce67458565b46bce32eaa9

It's fixed in pacman-git but hasn't been released in pacman yet. Once it's released, it will restore the old auto-extraction behaviour.

Given that circumstance, I'm not gonna push a hotfix, since I'd have to just revert it soon once Pacman is updated

@UndeadKernel: Hmm, you're right, something has clearly changed in makepkg, this exact PKGBUILD (plus leela-zero-git's almost-identical one) definitely used to work as-is a few weeks ago.

I think makepkg used to implicitly extract *.gz resources and now it doesn't anymore. I'll try to get to the bottom of this before just pushing out a hotfix.

I'm observing an error while installing:

==> Starting package()...
install: cannot stat '/home/boy/.cache/yay/leela-zero/src/weights.txt': No such file or directory
==> ERROR: A failure occurred in package().
    Aborting...
Error making: leela-zero

I don't see anywhere in the PKGBUILD where the weights.txt.gz file is uncompressed. Am I missing something obvious?

@janwil You will have more luck posting your findings so far in the ticket linked by @Liso; it's likely this is just a bug with Leela-Zero itself, not this particular package of it.

(You might also want to give leela-zero-git a try, just in case whatever the problem is has already been fixed. Leela-Zero is very slow to tag actual releases, so this is not too unlikely)

Hope that helps!

@Liso, I can confirm that my results of 'coredump gdb' and 'where' are similar to yours. What does this mean now and what can I do to fix this? Is there anything I can do in the first place? I am unfortunately not very good at debugging and fixing C++ myself :(

Best regards, Jan

Now I found that it is same as this issue https://github.com/leela-zero/leela-zero/issues/2438

@janwil , it seems I have same problem (in my case AMD Radeon RX 550X).

If I do coredumpctl list I get

Sun 2019-07-28 17:00:46 CEST 19240 1000 1000 11 present /var/tmp/pamac-build-i/leela-zero/src/leela-zero/build/tests

Then you could use "exe" to investigate problem:

coredumpctl gdb /var/tmp/pamac-build-i/leela-zero/src/leela-zero/build/tests

then you could write where and see stack. I got this:

Do you have same problem?

@apetresc, did a boot and clean git clone, but makepkg still gives the same error.

How should I debug this?

Best, Jan
