Thomas, All,
On 2016-01-25 00:07 +0100, Thomas Petazzoni spake thusly:
> libtorrent uses 1 bytes and 4 bytes __sync built-ins, so let's use the
> appropriate BR2_TOOLCHAIN_HAS_SYNC_x symbols instead of
> BR2_ARCH_HAS_ATOMICS. The rtorrent package, which is a reverse
> dependency of libtorrent, gets fixed as well.

The original build failure that prompted adding the atomics dependency
only reported errors about the __sunc_*_4() functions, but libtorrent
has been bumped sinc ethen.
I was not able to easily reproduce a failure so far, but I will try with
an arc toolchain (which is lacking __sync_*_1() functions...

Yann E. MORIN.
