Hello All!
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 for known kernel headers versions, and with a new
choice for manually-specified kernel headers version;
- 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.
For example:
- BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2012R1 selects
BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_3
- dvb-apps depends on BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_3
Changes v1 -> v2:
- typo and asciidoc syntax in the manual (Samuel, Thomas DS)
- add choice for custom kernel headers (Arnout)
- add check to strictly enforce selection (Thomas, Arnout)
- add help to choice (Thomas DS)
Regards,
Yann E. MORIN.
