<div>Background: uninative is a class that downloads a
precompiled host glibc for use in the sysroot, thus isolating
the native sysroot from the host environment. This means
greater sstate reuse, as instead of native builds being
dependent on the host system they're able to be shared between
all hosts. There is a reference tarball hosted on <a
moz-do-not-send="true" href="http://www.yoctoproject.org">www.yoctoproject.org</a>,
and the URL can be overridden by distros if you would prefer
to build your own.</div>
<div><br>
</div>
<div>We enable this in Poky so that we get greater reuse on the
autobuilders, and due to some issues with the C++ ABI the eSDK
generation in master now requires uninative to be enabled.
The question is: do we now enable uninative by default in
oe-core's nodistro (pointing at the yoctoproject tarball), or
do we keep it disabled by default and require the user to
enable uninative if they wish to build an eSDK?</div>
</div>

If Poky wants the default to use a prebuilt uninative that is fine,
but it should be not be the default in OE. In the spirit of
Bitbake, uninative should be a build dependency for eSDK with the
option of using a prebuilt one.<br>

<div>Personally I'm torn: I don't like eSDK not working out of
the box, but I don't really like oe-core nodistro depending on
uninative. </div>

Well Bitbake does not work out of the box on every host either.
There are packages needing to exist on the host as a prerequisite. I
see this in the same light.<br>
Do we make "Buildtools" a requirement to use Bitbake? <br>

<div>Though enabling uninative globally does mean everything
works out of the box, so following the principle of Least
Surprise that's what we should do.</div>

I see there are multiple versions, which one works with which
release?<br>
