Comment 1 Jerin 2022-01-27 10:22:37 CET 
Strangely build issue comes in acl or dlb2 driver.
Comment 2 Ferruh YIGIT 2022-01-27 13:31:16 CET 
ICC driver gives some warnings, we are aware of them, and current support allows warning in the ICC.
The main motivation of this decision is false positives by ICC, and the decision to not update code to silence the ICC.

But above has a build error for 'drivers/librte_event_cnxk.so.22.1', the detail of the error is not clear, log says file not found, it doesn't say which file:
icc: error #10236: File not found:  ''-Wl,-rpath,$ORIGIN/../lib:$ORIGIN/''


For testing, and perhaps as a workaround for now, can you please test with disabling event/cnxk driver?
“meson setup -Ddisable_drivers=event/cnxk build”
