Cover letter [Buildroot] [PATCH 0/7] Introduce the _AVAILABLE mechanism
Quoted 2 lines · Yann E. MORIN

The most problematic issue I've encountered is with X11r7. The top-level config option is BR2_PACKAGE_XORG7, but it is*not* a package.

I don't see what is the problem with that. USE_WCHAR is also not a package.
Except maybe the name is inconvenient.

What I would suggest is something like (just out of my tired brain):

choice
prompt "X Window System server type"

config BR2_PACKAGE_XSERVER_none
bool "None"

config BR2_PACKAGE_XSERVER_xorg #<-- Note how it currently is lower-case
bool "Modular X.org" # 'xorg' in the repository...
depends on BR2_PACKAGE_XSERVER_xorg_AVAILABLE
select BR2_HAS_XORG7

Quoted 7 lines

comment 'X.org requires largefile and C++ support'
depends on !BR2_PACKAGE_XSERVER_xorg_AVAILABLE

config BR2_PACKAGE_XSERVER_tinyx #<-- Ditto lower-case 'tinyx'...
bool "TinyX"
depends on BR2_PACKAGE_XSERVER_tinyx_AVAILABLE select BR2_HAS_XORG7

Actually, the XSERVER_tinyx/xorg option is wrongly placed: it should be
a sub-option of BR2_PACKAGE_XSERVER_XORG_SERVER. The choice has no real effect unless BR2_PACKAGE_XSERVER_XORG_SERVER is also selected (and all the xorg-server modules select the xorg-server). But that's a wholly different story.

Regards,
Arnout
