Seg Fault under 2.6.1.71

[ademasi]

Hi,

Thank you for your apps, it's super useful.
I have updated to the last version available of the RM system, reenable entware and remux to start zshelf, but if I try to start the app the screen stays white. By command line, I can see this error:

root@reMarkable:~# zshelf
EPD platform plugin loaded!

Maybe it does need a recompile? Did RM change their QT version?

In any case, I am available for testing if needed.

Regards, Alex.

Yes, rM 2.6 breaks all QT software packages on toltec. And reMarkable team does not provide development toolchain anymore so I can't rebuild it. Toltec dev team is developing solution, please be patient for a week or two.

[ademasi]

Thank you for your reply. It's too bad they did not share the toolchain...

PS: I really enjoy your work, spicetify is amazing, it's like I am using a different app.

I don't know if you've seen but apparently the toolchain has been updated to fix crashes with qt apps

[ard0gg]

I have rebuilt with the v2.0.1 toolchain and Zshelf does appear to work when launched from the command line. I am having issues when launched from remux (rmkit-dev/rmkit#122)

[Jab2870]

Anybody know if there is an update on this?

[ard0gg]

There is a PR (toltec-dev/toltec#338) to pull a fix into the Testing branch.

[matteodelabre]

This PR is for making launchers automatically preload rm2fb into launched apps. Unfortunately, this will not resolve this crash. To make Qt apps compatible with 2.6, they need to be rebuilt with toolchain v2, as mentioned above.

[matteodelabre]

FYI: Toltec testing now provides a version of Zshelf that is compatible with releases ⩾2.6.

@matteodelabre , how do I switch to toltec testing? Can't see anything in the documentation

Thanks in advance

@Jab2870 Please see the following comment: toltec-dev/toltec#341 (comment). We’re working on making this process easier and better documented soon.
