Hi Chris,
I did this in my local build:
diff --git a/build/external/packages/dpdk.mk b/build/external/packages/
dpdk.mk
index 49761cd56..a30ffd2ac 100644
--- a/build/external/packages/dpdk.mk
+++ b/build/external/packages/dpdk.mk
@@ -139,6 +139,7 @@ DPDK_MESON_ARGS = \
-Dtests=false \
"-Ddisable_drivers=$(DPDK_DRIVERS_DISABLED)" \
"-Ddisable_libs=$(DPDK_LIBS_DISABLED)" \
+ -Dibverbs_link=dlopen \
-Db_pie=true \
-Dmachine=$(DPDK_MACHINE) \
--buildtype=$(DPDK_BUILD_TYPE)
If I try to submit it upstream, I would probably do something nicer using a
DPDK_<something> environment variable, but for the moment this got me past
that error. I have not actually tested with an mlx5 device yet, so I don't
know if something additional will be required in order to forward packets
via an mlx5 NIC, but it did fix the error you pasted and
allow dpdk_plugin.so to be loaded.
