Subject: [Buildroot] [PATCH] toolchain/toolchain-external: warn for untested GCC/kernel version
Date: Sun, 2 Feb 2020 09:02:34 +0100 [thread overview]
Message-ID: <20200202080234.GA23672@scaer> (raw)

Arnout, All,
On 2020-01-13 23:59 +0100, Arnout Vandecappelle (Essensium/Mind) spake thusly:
> The oldest toolchain we test in the autobuilders is the Sourcery ARM
> toolchain which is GCC 4.8 and kernel headers 3.13. Therefore, it is
> likely that we're missing the required _AT_LEAST dependencies to exclude
> packages that don't build with older GCC/headers.
>
> Add a comment to the custom external toolchain that warns when an
> untested GCC or kernel headers version is selected.

> Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
Applied to master, thanks.
Regards,
Yann E. MORIN.
