[Buildroot] [PATCH 0/10] Add dependency on kernel headers

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

On 2014-02-16 18:27 +0100, Yann E. MORIN spake thusly:
> This series introduces infrastructure for packages to depend on the
> required version of kernel headers.
> 
> It follows the proposal made on the list:
>     http://lists.busybox.net/pipermail/buildroot/2014-February/088924.html
> 
> The basic idea is to add a symbol for each kernel header version, and
> have toolchains select the appropriate symbol, and packages depend on the
> appropriate symbol.
> 
> In this series:
> 
>   - such symbols are added for all kernel headers >= 3.0;
> 
>   - the internal toochain backend selects the appropriate symbol
>     without user-visible changes;
> 
>   - the predefined external toolchains select the appropriate symbols
>     without user-visible changes; those using kernel headers older than
>     3.0, select nothing, and a comment is added to state so;
> 
>   - for the custom external toolchain, a new choice is shown to the
>     user, to select the appropriate kernel headers version;
> 
>   - five packages are converted to take advantage of this.

There is one thing this series does not do: ensure the selection is
correct, by way of a new 'check_headers_version' herlper in
toolchain/helpers.mk.

This can be added later, or in a second iteration of the series, if need
be.

Yann E. MORIN.
