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

[kim]

Have you tried running the project on the phone with the debugger, or from a 
command line ?

I have found that this behaviour normally stems from something missing, and 
that will be displayed in the debugger or on the commandline.

[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 
, added a Makefile and 
hello.bmp, and placed those onto GitHub: 
.


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
