Hi,
I am trying to run VPP on an arm64 processor. I am using DPDK v16.11.
My board is having a non-pci ethernet interface I have added a PMD for that
in DPDK.
This PMD makes calls to an external library libxal which is platform
specific. All DPDK
apps. including testpmd work fine.
Using this DPDK I built vpp on my board:
# make V=1 build-release vpp_uses_external_dpdk=yes
vpp_dpdk_inc_dir=/root/work/vector/dpdk-v16.11/_install/include/dpdk
vpp_dpdk_lib_dir=/root/work/vector/dpdk-v16.11/_install/lib
My VPP startup.conf file:
unix {
interactive
log /tmp/vpp.log
cli-listen localhost:5002
}
api-trace {
on
}
dpdk {
coremask 0xff
vdev uio_xal_enet0 #dpdk vdev device
}
On staring VPP:

xal_init
---------
linking to libxal is not done, hence it is unable to find xal_init()
function def. This is visible from the ldd command output
for dpdk_plugin.so and lt-vpp. setting LD_LIBRARY_PATH is not helping too.

How can I link external libs to dpdk_plugin.so ? libxal is placed in
/usr/local/lib.
Thanks,
Devendra
