Bug ID: 356
Summary: Building dpdk with rte_vhost sometimes fails due to
missing rte_hash.h
Product: DPDK
Version: 19.05
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: minor
Priority: Normal
Component: vhost/virtio
Assignee: dev@dpdk.org
Reporter: jan.kryl@mayadata.io
Target Milestone: ---
This is because rte_vhost does not name rte_hash as its dependency in
lib/Makefile. Depending on -j and how knows what else the build either succeeds
or fails and is nondeterministic.

The fix is simple. DEPDIRS for librte_vhost in lib/Makefile needs to explicitly
mention librte_hash:
> DEPDIRS-librte_vhost := librte_eal librte_mempool librte_mbuf librte_ethdev \
> librte_net librte_hash

Patch fixing the issue merged in v19.11-rc3:

vhost: fix build dependency on hash lib
Compile librte_vhost/vhost_crypto.c needs the rte_hash.h
So we need the librte_hash to be compiled before vhost.
Add the DEPDIRs to make sure this.
