Hi, While compiling DPDK for VPP v23.02 on Centos 8, we saw below compilation error:- In file included from ../src-dpdk/drivers/common/mlx5/mlx5_common_mr.c:14: ../src-dpdk/drivers/common/mlx5/linux/mlx5_glue.h:15:10: fatal error: infiniband/mlx5dv.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ compilation terminated. ninja: build stopped: subcommand failed. Could not rebuild . make[3]: *** [packages/dpdk.mk:218: /opt/vpp/build/external/rpm/tmp/.dpdk.install.ok] Error 255 make[3]: Leaving directory '/opt/vpp/build/external' error: Bad exit status from /var/tmp/rpm-tmp.whpNsT (%install) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.whpNsT (%install) make[2]: *** [Makefile:113: vpp-ext-deps-23.02-8.x86_64.rpm] Error 1 make[2]: Leaving directory '/opt/vpp/build/external' make[1]: *** [Makefile:125: install-rpm] Error 2 make[1]: Leaving directory '/opt/vpp/build/external' make: *** [Makefile:627: install-ext-deps] Error 2 It is not able to find "infiniband/mlx5dv.h". What could be the reason for this error? Any package that might be missing and needs to install or are we missing something here? Thanks and Regards, Chinmaya Agarwal.
