[inho]

https://choccyhobnob.com/sdl2-2-0-8-on-raspberry-pi/
get rid of the default SDL2
$ sudo apt-get remove -y --force-yes libsdl2-dev
$ sudo apt-get autoremove -y
$ sudo apt-get install libasound2-dev libpulse-dev
Install SDL2 :
$ ./autogen
$ ./configure --disable-pulseaudio --disable-esd --disable-video-mir --disable-video-wayland --disable-video-opengl --host=arm-raspberry-linux-gnueabihf
# Another option ??? :
$ ./configure --disable-pulseaudio --disable-esd --disable-video-mir --disable-video-wayland --disable-video-x11 --disable-video-opengl
Try...
$ ./configure
$ make -j4 && sudo make install
$ sdl2-config –version
2.0.10 --> Great Success

Install SDL2_Image :
$ ./autogen.sh
$ ./configure
$ make -j4 && sudo make install
Install SDL2_ttf :
$ ./autogen.sh
$ ./configure
$ make -j4 && sudo make install
Install SDL2_mixer :
$ ./autogen.sh
$ ./configure
$ make -j4 && sudo make install
Install SDL2_net :
$ ./autogen.sh
$ ./configure
$ make -j4 && sudo make install

All done. Any program that uses SDL2 to draw to the framebuffer should now be doing it in hardware on the raspberry pis videocore4 using opengles2!
