Segfault on PocketBook Inkpad X

[KucharczykL]

• KOReader version: v2020.02-12-g611c423_2020-02-18
• Device: PocketBook InkPad X

Issue

After installation the application didn't launch. I have added a new device entry to the device file but then it crashes with a different error message. Before it crashes, two message boxes are displayed on top of each other. One saying which file is being loaded, the one underneath says something about color and memory usage.

Steps to reproduce

Install on InkPad X and add these entries to the koreader\frontend\device\pocketbook file:

-- PocketBook Inkpad X
local PocketBook1040 = PocketBook:new{
    model = "PB1040",
    isTouchDevice = yes,
    hasKeys = yes,
    hasFrontlight = yes,
    hasColorScreen = yes,
    isAlwaysPortrait = yes,
    display_dpi = 227,
    emu_events_dev = "/var/dev/shm/emu_events",
}

and

elseif codename == "PB1040" then
    return PocketBook1040

Then open the application via the bottom slide-up menu.

crash.log (if applicable)

Not actually a color screen, so, that can go away at the very least ^^.

(i.e., start from an Inkpad Pro 3 instead of the Color Lux. Quick maths says your dpi should be correct, though).

[NiLuJe]

It might also not need isAlwaysPortrait either, but that's for once it no longer faceplants on startup, since it should only affect touch input.

[NiLuJe]

Other than that, it, err, eerily sounds like InkView is once again doign some nasty crap behind our back.

Ideally, a core dump and/or a strace would be mightily helpful, like it was in #5861...

Also, that appears to be a new FW release, so I wouldn't mind having a look at a copy of your /usr/lib/libinkview.so to double-check that theory...

[KucharczykL]

Just removing the color and portrait options didn't solve it. As for your last comment, I don't know how to do it. I tried to search for an answer but in vain. Could you give me some advice?

[Frenzie]

As for strace, I understand you might be able to run something like strace -o log.txt -f koreader.app on the device itself without any mods. Not sure though.

As for /usr/lib/libinkview.so, that should be a file on the device itself.

[NiLuJe]

You'll need shell access to the device for all of those things. There ought to be some somewhat current info about how to achieve that buried in the PocketBook forum on MobileRead, but since I've never held a PB device myself, I can't really say much more.

Thanks for the pointers! Managed to get root ssh access. These are the spoils of my endeavor:

log.txt

libinkview.zip

Ah.

Good news: No new InkView shenanigans \o/.

Best news: You're using a build affected by #5861 (for... some reason? Did you move an existing installation?).

TL;DR: A clean install from >= 2020.02-11 should do the trick ;).

(Well, with the new device block ^^).

(Alternatively, make sure you have a libcurl_ko.so.4 file in koreader's libs folder, and delete the libcurl.so.4 you'll find in the same place).

[KucharczykL]

You are right. During testing different builds I probably forgot to replace the .app file as well. It works now! Thank you for your help.
