This was just recently flagged to us and discussed on this email thread on
the dpdk dev list.
http://inbox.dpdk.org/dev/20201029091638.26646-1-getelson@nvidia.com/
At the end of the discussion the follow was noted in our docs as a known
issue for DPDK.
"pkg-config v0.27 supplied with RHEL-7 does not process correctly libdpdk.pc Libs.private section."
If you have any suggestions as to how we could work around this issue, I'd
be very keen to hear them, though unfortunately it does seem to be a bug
in pkg-config that is outside of our control.
Regards,
/Bruce
