Subject: [dpdk-dev] [PATCH 2/2] Fix compile issue of eal with icc compile
Date: Wed, 10 Dec 2014 18:46:42 +0800
Message-ID: <1418208402-7597-3-git-send-email-michael.qiu@intel.com> (raw)
In-Reply-To: <1418208402-7597-1-git-send-email-michael.qiu@intel.com>

lib/librte_eal/linuxapp/eal/eal.c(461): error #2259: non-pointer
conversion from "long long" to "void *" may lose significant bits
   RTE_PTR_ALIGN_CEIL((uintptr_t)addr, RTE_PGSIZE_16M);

The root cause is that "RTE_PGSIZE_16M" is defined as unsigned long long.
But in i686 platform "void *" is 32-bit.
It is safe to cast to size_t and make it works in both 32 & 64-bit
platform.
