Modern equivalent of --with-egl-window-system=rpi ?

[Michael Tyson]

Cheers for the reply Sebastian!

Alas, nope - here’s what it says ("Failed to bind OpenGL API: EGL_BAD_PARAMETER”):

Previously, this could be accomplished by appending --with-egl-window-system=rpi to the configure flags, and adding some environment variables. In 1.4.1, configure doesn’t seem to recognise this flag any more.

Attempting to rebuild with --disable-wayland, but I’m not hopeful.
