"ERROR: No available video device" at calling SDL_Init(SDL_INIT_VIDEO) in SDL 2.0 is making me eat my hair

SDL Development
1

I’m currently attempting to build and use SDL under Ubuntu
installations. The only solutions I’ve come across ask me to download
and install a bunch of vague packages, which I did on test systems
(and it didn’t solve the problem I’m encountering at ALL). Been at
this for two days, about at my wit’s end here. I’ve tried setting
SDL_VIDEODRIVER to something specific like x11 or fbcon, and on one
test system I managed to get SDL to output something else than “ERROR:
No available video device” with such set to x11 (“ERROR: a bunch of
crap about missing symbols in X Window System labeled libraries”)
(can’t remember the steps or all the vague packages it took to get to
that point) (usually when custom setting such I just wind up with
"ERROR: (name here) not available."). I can’t see what else DISPLAY
could be set to other than :0, mainly because I don’t understand much
about the environment variable.

If an actual solution can be found that doesn’t leave a mess on a test
system, that would be wonderful. I’d really like to be able to move
on past initializing SDL so that I can try out the new video
functions.

After installing those package, do you rebuild SDL2?

Alright I rebuilt it using cmake and compiled my code using…

gcc -x c -ansi sdl2-config --cflags -o ./0026 ./0026.c sdl2-config --libs -ldl -lm -lpthread -L/usr/X11R6/lib -lX11 -lXmu -lXext -lXt

-and every time I rerun my code I get a ton of the following:

The code works anyway with those errors?

AFAIK you should not link X11 libraries directly:

-lX11 -lXmu -lXext -lXt should be dinamically linked by SDL, maybe that
forcing linking yourself you are screwing the dynamic extension loading SDL
does.On Wed, Nov 13, 2013 at 10:36 PM, Charles Swain wrote:

If an actual solution can be found that doesn’t leave a mess on a test

on past initializing SDL so that I can try out the new video
functions.
