Workaround to run under MacOS about lv_port_pc_eclipse

[kisvegabor]

Hi,

Thank you for the reporting the issue and telling our solution.

I implemented SDL_Iinit in a thread because on Windows drawing was possible on in that "context" when the init was called. So the init was required to move to the thread where the drawing happens.

I will immerse in it as I will have time. Until that time your solution surely will help to others on OSX.

I ran into the same problem with SDL. I am using Eclipse Photon Release (4.8.0) and was having the exact issue you described. Waiting for hardware and wanted to get started understanding this UX library.
Much appreciate for the time you put into finding this thoughtful solution.

It works perfectly on my MacOS 10.14. I owe you a beer!

I've got the same issue.
Is there a patch or a fork/branch that I can access to get a a working copy of the source to compile ??
Thanks :)

Hi,

I have create two pull requests to make it work on OSX latest version. Tested locally:

#21
lvgl/lv_drivers#16

Thanks.

[kisvegabor]

Both merged! Thank you very much!

It should solve the majoraíty of the OSX issues, so close these issue.

I just tried building from the github master and running on my system (High Sierra, eclipse, sdl2 installed from Homebrew) and got the same crash. The only change I needed to make to get it to build was to remove the #define of USE_FBDEV in lv_drv_conf.h.

It looks like the SDL event pump is still running from the monitor thread.

It looks like this was broken in commit 5e42767 when SDL_PollEvent() was added to monitor_sdl_refr_core().

Yep, I see the same crash again.

It runs if you wrap the while(SDL_PollEvent(&event)) with an #ifndef MONITOR_APPLE
