please help me
raspberry p2 and SDL2

before i've installed
(advice in ttps://solarianprogrammer.com/2015/01/22/raspberry-pi-raspbian-getting-started-sdl-2/)

sudo apt-get install build-essential
libfreeimage-dev libopenal-dev libpango1.0-dev
libsndfile-dev libudev-dev libasound2-dev libjpeg8-dev
libtiff5-dev libwebp-dev automake

i've got SDL2-2.0.3.tar.gz
tar
cd SDL2-2.0.3 && mkdir build && cd build
../configure --disable-pulseaudio --disable-esd --disable-video-mir --disable-video-wayland --disable-video-x11 --disable-video-opengl
make
sudo make install
all above is ok
sudo ldconfig

now start my simple test.c

#include <SDL2/SDL.H>
#include <stdio.h>
#include <stdlib.h>

int main (){

if (SDL_Init(SDL_INIT_EVERYTHING) !=0) {
printf(
"\nUnable to initialize SDL: %s\n",
SDL_GetError()
);
return 1;
}
SDL_Delay(1000);

SDL_Quit();
return 0;
}

compile
gcc -Wall -o test test.c -lSDL2
or if you want is the same
gcc -Wall -o test test.c `sdl2-config --cflags --libs`

compile with no error

//execute
./test

Unable to initialize SDL:no available video device

is the same with
sudo ./test

or if start

with sudo startx ./test

please someone once for all could explain to a idiot child like me
how compile SDL2 for use in raspberry
with OpenGL ES and X server

i'm very frustrating
and hope someone clear my mind after days of compile and recompile
with same effect
best regards

You should give the binaries Buildbot generates a try...For example: https://buildbot.libsdl.org/sdl-builds/sdl-raspberrypi/sdl-raspberrypi-825.tar.xz (just uncompress to /)

thanks Gabriel for your reply
i will do your advice this night (for me)
just tar .tar.xz file in a root?
please could you explain me why my compilation fail to run if all
is done in a right way?
i've already run sdl2 with x server bat is very slow
i'hope this way is faster than previous
best regards

Hi, I'm getting the same exact problem. Did you manage to fix it?
It seems it's not possible to init video on Rapsberry Pi 2.

yes and no.
i'll try to explain
after a lot of trial, compile and recompile with advice above,
i was down.
the issue , i guess, were in dependencies installed and in configure
setting wrong .
i've followed all the advice above before used with success with b+ but with pi 2 doesn't .
no one ,also in raspberry forum enlightened me.
so it's better to get a precompiled build from
https://buildbot.libsdl.org/sdl-builds/sdl-raspberrypi/?C=M;O=D
unpack in root but be carefull because it overwrites previous installation and makes a mess
it works but i don't understand why i cannot build on my own sdl2 library with my raspberry pi 2.
i hope this help you.

I will be compiling SDL2 for raspberry pi2 this weekend, so if you aren't having any success still, I'll report my findings. On 26 Feb 2015 02:58, "Scap_Pato" wrote:

Thanks a lot .
works!

Yes that did the trick.

In the end that is what I used for compiling SDL 2 in Raspberry Pi 2:
