Subject: [dpdk-dev] [PATCH v2 5/5] build: add libatomic dependency for 32-bit clang compile
Date: Tue, 28 May 2019 12:07:48 +0100	[thread overview]
Message-ID: <20190528110748.10772-6-bruce.richardson@intel.com> (raw)
In-Reply-To: <20190528110748.10772-1-bruce.richardson@intel.com>

When compiling with clang on 32-bit platforms, we are missing copies
of 64-bit atomic functions. We can solve this by linking against
libatomic for the drivers and libs which need those atomic ops.
