Subject: [dpdk-dev] [PATCH] test-meson-builds: add a 32-bit build
Date: Thu,  5 Nov 2020 11:07:28 +0000
Message-ID: <20201105110728.220957-1-bruce.richardson@intel.com> (raw)

It's reasonably common for patches to have issues when built on 32-bits, so
to prevent this, we can add a 32-bit build (if supported) to the
"test-meson-builds.sh" script. The tricky bit is using a valid
PKG_CONFIG_LIBDIR, so for now we use two common possibilities for where that
should point to in order to get a successful build.
