[SailfishDevel] QML creates a Segfault

[Jonni Rainisto]

Maybe you just didn't notice the restrictions part (ie script cannot access properties, methods or other attributes of the qml item etc).
Hard to say without seeing your workerscript implementation.

OK, its just a bit weird that the same program works without a WorkerScript.
The WorkerScript is just to make the gui more repsonsive it has no relevance to the function.

Thanks.

Hi,

when trying to download data in a WorkerScript thread I got this:


bash: line 1: 1459 Segmentation fault QT_NO_JOURNALD_LOG=1 DISPLAY=:0.0 /usr/bin/CalDav

Can somebody explain if I can avoid this or what the reason is ?


That script part is  how Qt Creator runs your application in the device/emulator. So it just means that /usr/bin/CalDav crashed to a SEGFAULT and you'll need to figure out why.

Qt Creator launches the application in the device/emulator almost like this:

ssh nemo at device_address "QT_NO_JOURNALD_LOG=1 DISPLAY=:0.0 /usr/bin/applicationname"

It does not use ssh command, but an ssh library, which is part of Qt Creator.

The QT_NO_JOURNALD_LOG =1 is there to make the application not put its output to journald, but to stdout/stderr instead so that Qt Creator can display it.

Best regards,
 Juha
