Subject: [Buildroot] [PATCH] [RFC] package/boost: Boost.Atomic needs atomic intrinsics
Date: Mon,  5 Dec 2022 13:54:22 +0100	[thread overview]
Message-ID: <20221205125423.13983-1-buildroot@heine.tech> (raw)

From: Michael <buildroot@heine.tech>

similar to previous problems with nios2 and not-available atomic ints
the build for Boost.Atomics also fails for ARC Targets which don't
have the ATOMICS_EXT flag set.

according to [0] "Boost.Atomic has a hard requirement of the native
atomic operations on bytes". The same tests mentioned there fail for
ARC.

so introduce a dependency on BR2_ARC_ATOMIC_EXT for BR2_arc.

Fixes:

I'm not 100% sure if BR2_ARC_ATOMIC_EXT is the correct
flag to use. I'm open to suggestions for better ways and what to
propagate to dependent packages.
