Directory restrictions

[LibrEars]

Hi all,

can you assist me in sorting out access problems from the flatpack installation (Arduino IDE 1.8.13 - Debian 10 GNU/Linux)? The IDE tries to use the critical file 'crtatmega328pb.o' located in /home/user/.arduino15/packages/uStepper/hardware/avr/2.2.1/tools/lib but has no access.
The file is also located in /var/lib/flatpak/app/cc.arduino.arduinoide/x86_64/stable/275e[... long number...]ac/files/Arduino/hardware/tools/avr/avr/lib/avr5/crtatmega328pb.o but I do not now how to tell the compiler to use this directory instead...

For the error log see the issue asked to the uStepperS developers (they recommended me to use the direct install of the IDE...): uStepper/uStepperS#26

I double checked on a virtual windows machine where the access to the stepper works.

Thank you and Greetings

So the problem is the following, by default a flatpak app does not have access to home and if it needs to use ~/.somedir it would use ~/.var/app/APP-ID/.somedir instead. This flatpak in particular by default has home access so it should use ~/somedir instead of the local ~/.var/.../.somedir dir.

If you followed the advice at #25 for example, you blocked access to the dir ~/.somedir in favour of the one inside ~/.var, which only means you need to copy or move its contents from ~/.somedir to their ~/.var/app/... counterpart.

This is not precisely what you asked, as you are talking about /var which is more involved and should not be touched, but it might be related to whats causing the issue.
