This looks like a regression in 20.11 LTS with older meson. Adding 20.11 LTS maintainers to the thread. Afaics, this is triggered by "build: fix warnings when running external commands". And reverting it is enough to fix the error with meson 0.47.1. https://github.com/david-marchand/dpdk/commits/20.11 https://github.com/david-marchand/dpdk/actions/runs/3113099408 -- David Marchand _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
