Subject: [dpdk-dev] [PATCH v2 2/4] examples/ip_pipeline: fix build for x86_64 without SSE4.2
Date: Tue, 16 Feb 2016 07:46:08 +0100 [thread overview]
Message-ID: <1455605170-16137-3-git-send-email-thomas.monjalon@6wind.com> (raw)
In-Reply-To: <1455605170-16137-1-git-send-email-thomas.monjalon@6wind.com>
The compiler cannot use _mm_crc32_u64:
examples/ip_pipeline/pipeline/hash_func.h:165:9:
error: implicit declaration of function '_mm_crc32_u64' is invalid in C99
