Just install pahole-git or wait till arch will bring a update for pahole. This will fix it.

@robson-66

PDS is currently not compiling if CONFIG_NUMA is enabled. Just disable it for now.

Is there some additional problem or feature missing if disable this option to PDS ?

No idea then. The CachyOS PDS and BMQ Kernel went without problems, when disabling NUMA.

Edit: You can test this patch, there is a fix from torivc9 in: https://github.com/CachyOS/kernel-patches/blob/master/6.3/sched/0001-prjc-cachy.patch

[robson-66]

For me on Arch Linux after disabling NUMA

# Set to "true" to disable NUMA, lowering overhead, but breaking CUDA/NvEnc on Nvidia equipped systems - Kernel default is "false"
_numadisable="true"

The construction went well.

But there was an entry in the log

kwi 26 12:19:01 pc kernel: memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL, pid=1 'systemd'

[Everest10]

set _numadisable="true" cant compile on Fedora 38

same errors reported
