Jolla C and SDL2
asked 2016-11-11 15:00:25 +0300
I have created a game using SDL2, on my device (first version Jolla) the game works perfectly. It seams that under Jolla C it renders a black screen, that's why it was rejected on the market. I tested it under emulator in all modes (Jolla, JollaC, tablet) and there is no problem.
After sending a Dropbox link for the game to the developer mailing list it was verified that the game runs as sound plays correctly but the screen is black. So I prussume there is a bug on the actual JollaC device, either the SDL2_image library doesn't load correctly the images or the SDL2 doesn't create a full screen window. I use the SDL2_image library only for loading images and the SDL2 library to create the full screen window and handle touch events, all rendering is done with OpenGL ES calls.
Can anyone with JollaC (and maybe a tablet) verify the problem? If needed I could provide a dummy game that just renders a single image but saves a log of every SDL2 and OpenGL ES call and you could share it with us?
How about some debug logs first?

The log file will be created under the folder: /home/nemo/.local/share/harbour-dummy/Home/log.txt
In my Jolla device (first generation): As I didn't want to hard code dimension for screen I create a dummy window and query the dimensions later so that I can scale my images
=> 161111:16:59:57 dummy full screen window width 540, height 960
after doing some math for my game I create the actual window for rendering my scaled images
If you download my log you will see that my code is resilient, it works even if some images and/or sounds are missing
