[SailfishDevel] SDL2 without OpenGL, nothing but a black screen

[Lauri Nurmi]

Ahoy,

I was coding something simple with 2D-only graphics using SDL2, and 
noticed that drawing graphics that does work in the emulator, does not 
work on the actual phone.

To demonstrate that, I copied the example code from 
<https://wiki.libsdl.org/SDL_CreateRenderer>, added a Makefile and 
hello.bmp, and placed those onto GitHub: 
<https://github.com/lanurmi/sailfish-minimal-sdl>.

As also described in README.md, the sample runs fine in the emulator, 
but fails to show anything but a black screen on the actual phone. 
Additionally, if the |SDL_RENDERER_SOFTWARE ||flag is used instead of 
SDL_RENDERER_ACCELERATED, the sample still runs on the emulator, but 
causes a segmentation fault on the phone.

The phone is running 1.0.5.19.

Am I doing something wrong? (Can't imagine what that would be.)


Best Regards,
Lauri Nurmi
