Alex, All,

On 2015-10-01 00:12 +0300, Alex Suykov spake thusly:
> In case (PKG)_VERSION is empty, do not attempt to download sources
> for the package. Attempts to download (package)-undefined.tar.gz
> are pointless, the file is not likely to exist.
> 
> Also, output/build/(package) looks better and makes more sense than
> output/build/(package)-undefined for such packages.
> 
> Non-versioned packages within buildroot: skeleton and mke2img.

Wrong. We also have:
    googlefontdirectory
    gadgetfs-test
  * initscripts
 r+ * mcookie
    cache-calibrator

[*] like skeleton and mke2img, those are internal packages. so it's
normal they have no version.
[+] mcookie is now provided by util-linux, so we should probably get rid
of our internal copy.

Also, there has been a new package discussed on the list today that had
no version either (libsoil):
    http://lists.busybox.net/pipermail/buildroot/2015-September/140370.html
    http://lists.busybox.net/pipermail/buildroot/2015-September/140480.html
    http://lists.busybox.net/pipermail/buildroot/2015-September/140508.html

And yes, I would like to keep being able to have packages without a
version.Even if  upstream are not playing by the rules, it is perfectly
legit that we have support for that.

Yann E. MORIN.
