Subject: Re: [dpdk-users] [dpdk-dev] Issue->Dpdk for arm cortex-a15 compilation
Date: Tue, 16 May 2017 17:25:20 +0530 [thread overview]

Hi All
Attached is the complete env variables file
I have added RTE_KERNELDIR too
Also I am now using gnu-eabi version 5.4.0
[arm-openwrt-linux-muslgnueabi-gcc (LEDE GCC 5.4.0 r3909-6411a12) 5.4.0]
But I am still getting the same error
Currently I am not using buildroot
Is there any step by step available guide for cross compiling dpdk using
buildroot for target arm cortex-a15 using some external toolchain.
I found this http://dpdk.org/ml/archives/announce/2015-October/000066.html
Please advise
Thanks
