Re: [dpdk-users] [dpdk-dev] Issue->Dpdk for arm cortex-a15 compilation

[Jimmy Carter <jimmycarter256@gmail.com>]

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
