I don't think that your issue is related but just note that my builds have always been done with gnueabi. > 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 > There is a patch to Buildroot that can help you with the setup.

I build DPDK via Buildroot but this is unsupported by the DPDK upstream. I could build DPDK for Cortex-A7, Cortex-A9 and Cortex-A15 in the past. I run regular builds of the master branch and I can see no breakage for the arm-armv7a-linuxapp-gcc configuration. Regards Jan > > Thanks > Akshay
