Subject: [dpdk-dev] [PATCH v3 2/4] examples/l2fwd-keepalive: skip build when no librt
Date: Wed, 11 Nov 2020 17:48:43 +0000	[thread overview]
Message-ID: <20201111174845.1768044-2-bruce.richardson@intel.com> (raw)
In-Reply-To: <20201111174845.1768044-1-bruce.richardson@intel.com>

When librt is not present on a system, processing the meson.build file
for this example application causes an error. Make the library
non-mandatory and just mark the example as unbuildable if it is
not present.

Fixes: 89f0711f9ddf ("examples: build some samples with meson")
Cc: stable@dpdk.org
