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

[Jimmy Carter]

Hi All

I am using dpdk16.11.1 and want to use openwrt external toolchain so that I
can cross compile for arm cortex 15
neon.(arm_cortex-a15+neon-vfpv4_gcc-5.4.0_musl_eabi)
My target board is Tp link archer C2600.
I am have assigned these env variables but still getting compilation error

export
STAGING_DIR=/home/xav-101000739/ovslede/source/staging_dir/toolchain-arm_cortex-a15+neon-vfpv4_gcc-5.4.0_musl_eabi
export
PATH=$PATH:/home/xav-101000739/ovslede/source/staging_dir/toolchain-arm_cortex-a15+neon-vfpv4_gcc-5.4.0_musl_eabi/bin


export CROSS=arm-openwrt-linux-
export DPDK_TARGET=arm-armv7a-linuxapp-gcc
export DPDK_DIR=$PWD
export DPDK_BUILD=$DPDK_DIR/$DPDK_TARGET
export
CFLAGS+=-I/home/xav-101000739/ovslede/source/staging_dir/toolchain-arm_cortex-a15+neon-vfpv4_gcc-5.4.0_musl_eabi
export RTE_SDK=$PWD
export RTE_TARGET=arm-armv7a-linuxapp-gcc
export DPDK_BUILD_DIR=arm-armv7a-linuxapp-gcc


Error:Attached file

Please advise
Does dpdk have support for openwrt (arm cortex a15)

Thanks
Akshay
