<pre>Mesa builds started last night to fail to:
drivers/dri2/platform_wayland.c:48:33: fatal error: wayland-egl-backend.h: No
such file or directory
Apparently this file should be now provided by libwayland instead of being
included with Mesa. However, there was no configure error about pkgconfig not
finding wayland-egl-backend.pc file provided by libwayland, or it having too
old version.
Looking at the guilty commit 1db4ec05462914096b1f243e9b2af7e71cf38622, it seems
to be checking for wayland-egl instead, and requiring version 1.15 of it.
E.g. on Ubuntu 16.04, wayland-egl.pc content is:
--------------------------
prefix=/usr
exec_prefix=${prefix}
libdir=${prefix}/lib/x86_64-linux-gnu
includedir=${prefix}/include
Name: wayland-egl
Description: Mesa wayland-egl library
Version: 17.2.8
Requires: wayland-client
Libs: -L${libdir} -lwayland-egl
Cflags: -I${includedir}
--------------------------
Which is provided by libegl1-mesa-dev i.e. Mesa, and pc file version is
obviously large enough as its version comes from Mesa.
However, libegl1-mesa-dev package doesn't provide any Wayland headers, only EGL
ones.
Installing latest version of libwayland from git naturally fixes this, but Mesa
autoconfig (and Meson) check is clearly broken.</pre>
