Again, silly questions from someone not familiar with wpewebkit: what is "WPE backend" in this context, and how does "WPE backend" map to what we have (or don't have) in Buildroot? In Buildroot as far as I can see, wpewebkit always depends on wpebackend-fdo, which depends on libwpe. Does this mean that we are so far only using "libwpe" and never "WPE backend"? > In 2.50 it is only enabled by default in developer > mode, so add an option for it, with sub-options for the DRM and > Wayland platforms.

So far, so good. > The Wayland platform selects wayland and wayland-protocols even though > wpewebkit itself selects them today: that is only for wpebackend-fdo, > and the Wayland platform needs them on its own. But if wayland/wayland-protocols are only for wpebackend-fdo, why isn't wpebackend-fdo selecting them, instead of wpewebkit? > Every WPE Platform display compiles an XKB keymap with libxkbcommon. > Without the xkeyboard-config data this fails and the application > crashes, so select xkeyboard-config. > > Pass ENABLE_WPE_PLATFORM explicitly in both cases, as upstream > enables it by default starting with 2.54. > > Signed-off-by: Joseph Telaak Otherwise, looks good to me. Probably no need to resend, just provide a little bit more details on the questions asked on PATCH 1/2 and 2/2 and that should be good. Adrian: here as well, your review would be appreciated :-) Thanks a lot!
