highest priority over-ride.

[PATCH 2/3] native.bbclass: drop _virtclass-native and _virtclass-nativesdk overrides

[Andre McCurdy]

The _virtclass-XXX over-rides are problematic in that they are higher
priority than _forcevariable, which is documented as being the
highest priority over-ride.

Since they are now obsolete (replaced by _class-native and
_class-nativesdk) drop them entirely rather than try to fix their
priority.

[PATCH 3/3] bitbake.conf: drop _build-${BUILD_OS} over-ride

[Andre McCurdy]

Building on a host OS other than a recent version of Linux is not
recommended or supported. Drop the historical _build-${BUILD_OS}
over-ride to avoid giving the impression that other host OS's might
be supported.

having .= appear was letting user know how it was being lined up in 
overrides, now it might raise question in new readers mind as to why ':' 
is prepended

so ideally it would be good to define LIBCOVERRIDE = "libc-<libc>" but 
that might add useless : in case of native recipes

Maybe bitbake should just eat consecutive separators without consequence 
but that seems less than ideal too.

if this is not causing issues, I would suggest to keep this in.

I'm with Khem. meta-darwin and meta-mingw are things, even if they
haven't been updated in years. If interest arises they shouldn't have
too many barriers to starting development again. I've also started to
attempt to build on a FreeBSD host.

meta-mingw builds Windows binaries from Linux and meta-darwin builds
Darwin binaries from Linux, so they're not relevant.

People *are* at least trying to use Windows Subsystem for Linux to
build Yocto on Windows, but I suspect as far as bitbake is concerned
that is Linux.  There's no practical way we can build on macOS right
now due to the recent security changes.

Builds on BSD would be interesting, I'm curious as to how much breaks
from GNU userland expectations and whether the build override is
actually useful.

Neat, I only took a quick look; I guess I misinterpreted their purposes.

When I tried, early in the WSL testing, bitbake wouldn't start due to
some missing syscalls. inotify related, IIRC.

The problem I'm running into right now is pseudo. FreeBSD uses a
different API for extended attributes, so all the various xattr_...
things don't work. I might need to make it depend on a port of the
xattr wrappers.

Outside of that, I've been using a FreeBSD hosted cross toolchain for
embedded Linux for years. It works well on its own. Hopefully the
build-* overrides will be helpful for the small differences I've
noticed.

Even if bitbake could run on WSL, it’d be horribly slow. I/O on WSL is
*terrible* right now, docker or a VM wipes the floor with it. I’m sure
it’ll be viable eventually, though :)

Yes, it's a shame LIBCOVERRIDE was defined with a leading : to begin
with, but now it's done that way I'm not sure it's worth redefining
(there could be classes or recipe in other layers which reference
LIBCOVERRIDE and expect the leading : to be there).

Bitbake already does eat consecutive separators (it needs to for
native recipes, since native recipes set MACHINEOVERRIDES to "").

oh in this case then please remove it, its not an ABI element that
we need to keep compatibility with and layers who use it should
change to new ways.

A patch removing the leading : was rejected about a month ago:

  http://lists.openembedded.org/pipermail/openembedded-core/2018-April/149742.html
  http://lists.openembedded.org/pipermail/openembedded-core/2018-April/149743.html

If you think RP was wrong then maybe reply to that thread and try to
get the original patch merged?
