Summary: SDL_CreateWindow fails on systems without X11, if libEGL.so is not linked manually or preloaded

Description Danilo Spinella 2019-05-26 21:18:11 UTC 
In a configuration with OpenGL ES v1/v2 and EGL enabled, a program linked with -lSDL2 fails to create a window.

I've also tested the bug against this simple application:
https://wiki.libsdl.org/SDL_GetWindowSurface


SDL_Error() report: "failed to create a window surface".

If I link the application with EGL ("-lEGL") it works flawlessy, the same if I use LD_PRELOAD=/usr/lib/libEGL.so.

Running a strace of the application, it loads /usr/lib/wayland-egl.so when it is isn't compiled with "-lEGL".

As an additional note, I am running a musl based system. It doens't seem to be related though.
