Subject: [dpdk-dev] [PATCH v1] app/test: zcd needs to be initialised to fix gcc compile error
Date: Wed, 4 Nov 2020 17:03:06 +0000 [thread overview]
Message-ID: <20201104170306.1688771-1-conor.walsh@intel.com> (raw)
When DPDK is compiled with gcc < 9 with the optimization level set to 1
gcc sees zcd in test_ring.h as possibly being uninitialised. To correct
this error zcd has been initialised to {0} in
test_ring_mt_peek_stress_zc.c.
