calculator segfaults on 2.7

[rbowen]

Context: Running 2.7 (updated this morning) on an RM2. I've never installed any third-party anything on this device before today.

Installed remux and calculator, and then attempted to launch calculator:

May 26 17:57:15 reMarkable remux[3034]: virtual void EPRenderContext::renderNextFrame(QSGRenderer*, uint) can't render without a renderer

Running directly from cli gives:

EPD platform plugin loaded!
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
Creating window
virtual void EPRenderContext::renderNextFrame(QSGRenderer*, uint) can't render without a renderer
Segmentation fault

(ie, same output, plus the segfault line.)

Please let me know if I can provide any other details.

Hi @rbowen, thanks for your report! I believe this is expected behavior, see #322. Most packages using the Qt framework will not work on ⩾2.6 unless they are compiled with the v2 branch of our toolchain. Some work towards migrating our packages to use toolchain v2 has been done on the support-2.6 branch, but it needs more testing before I can make it into a PR.

Ah right, I had forgotten that we hadn't pushed any of that into testing yet. We probably should do that soon as 2.7 is now out.

Ok, thank you for the confirmation and for the swift response. I'll wait a few weeks and try again, then, should I?
