EAL: FATAL: unsupported cpu type.
EAL: unsupported cpu type.

Looks like it's requiring AVX-512. Build time CPU auto-detection, I assume.

I rebuilt this package on a machine with AVX512 support, so your immediate issue should be fixed with dpdk-22.07-3

But ideally, the build config must be deterministic and do not depend on the host.

I checked its build and do not see how to enable specific CPU features https://github.com/DPDK/dpdk/blob/main/meson.build

Could anyone with more experience in DPDK tell me how to make its build deterministic?

You probably want "-Dplatform=generic" as suggested by https://github.com/DPDK/dpdk/blob/main/doc/guides/linux_gsg/build_dpdk.rst

This option defaults to "native": https://github.com/DPDK/dpdk/blob/v22.07/meson_options.txt#L43

Added "-Dplatform=generic" in r1352066

This bug should be fixed now. @felix, if you have time, could you please check that AVX512 is still enabled at the host you built DPDK earlier? The information is printed early at the configuration stage.

It has "platform: generic" at the end of configuration output, but still tests for AVX512 in various ways and succeeded. I have then installed the resulting package and verified that the error messages in OP are not present.

So yes, it has been fixed :)
