[Bug] UltimateMangaReader crash when opening any manga

[Firestorm7893]

As the title says, whenever i try to open a manga the screen blanks and on the bottom it says KFmon initialized. I tried using an older version but it didn't fix the issue.

My device is a Libre h2o

Wich FW version are you using ?

[Firestorm7893]

Right now I'm on firmware 4.32.19501

[Firestorm7893]

update: I downgraded the firmware to 4.28 and it still happens. I think the problem is due to the fact that I'm forced to use a different version of the qt library at this point.

You may need to manually delete / rename the cache folder, it can happen sometimes

i tried it but unfortunately still crashes. Right now I'm using kfmon 1.4.5 with the latest nickelmenu. Maybe i missed something during the installation?

I have another friend who have a libra h2o and he is facing a lot of problem too.. Hmm i don't have any solution at this moment sadly. I know there is some problem with the screen size detection. Please, post your log.txt inside the folder of the app.

Ok the log says it fails to save the thumbnail. And then looks like it fails when resizing the image? Kind of? log.txt

It's seem there is a lot of problem with a lot of people with the resize

void Simd::Neon::ResizeBilinear ../UltimateMangaReader-Qt5/thirdparty/simdimageresize.cpp:389: void Simd::Neon::ResizeBilinear(const uint8_t*, size_t, size_t, size_t, uint8_t*, size_t, size_t, size_t) [with unsigned int channelCount = 1; uint8_t = unsigned char; size_t = unsigned int]: AssertiondstWidth >= A' failed.`

I have some friend who have the same problem and error with h2o. However i do not have any problem with my kobo forma. i do not know how to fix that but i know that the screensize in the imageprocessingnative.cpp return a 0 pixel height wich result in simdimageresizer to crash.

What about just commenting out the assert ? i tried setting up all the tool chain put I got stuck unfortunately.

if I could I would try to just remove that

[AnnoyedDev]

It is not possible because it would make the image way too large or way too small, i have already done a temp fix for one user in my fork, but it does not solve the problem, instead it make the image sometimes too small, sometimes too big, and it is a per-user workaround wich is impraticable in real conditions.

I do not think i have enough knowledge to fix that, but what i can tell for the original dev is it happen on h2o, on clara hd but NOT on the kobo forma.

for some user, chaning the version of the qt folder (by downloading older version) fixe the problem but create another (no touch working, still crashing etc).

[Firestorm7893]

I understand. But I'd still like to give it a shot with the basic knowledge I have. Only issue I have is setting up the toolchain. Particularly the SYSROOT parameter. What should it be ?

Sorry for bothering you!

Having the app working is not a problem, it's a challenge now

[AnnoyedDev]

sysroot is the system root of the arm built system

[Firestorm7893]

Latest version fixes everything
