Luca also mentioned an issue on Centos 8. Interestingly, I am not able to reproduce it in my OBS env. https://build.opensuse.org/build/home:dmarchan/home_bluca_dpdk_CentOS_8/aarch64/dpdk/_log [ 135s] [118/2414] cc -Ilib/76b5a35@@rte_net@sta -Ilib -I../lib -Ilib/librte_net -I../lib/librte_net -I. -I../ -Iconfig -I../config -Ilib/librte_eal/include -I../lib/librte_eal/include -Ilib/librte_eal/linux/include -I../lib/librte_eal/linux/include -Ilib/librte_eal/arm/include -I../lib/librte_eal/arm/include -Ilib/librte_eal/common -I../lib/librte_eal/common -Ilib/librte_eal -I../lib/librte_eal -Ilib/librte_kvargs -I../lib/librte_kvargs -Ilib/librte_telemetry/../librte_metrics -I../lib/librte_telemetry/../librte_metrics -Ilib/librte_telemetry -I../lib/librte_telemetry -Ilib/librte_mbuf -I../lib/librte_mbuf -Ilib/librte_mempool -I../lib/librte_mempool -Ilib/librte_ring -I../lib/librte_ring -fdiagnostics-color=always -pipe -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -O3 -include rte_config.h -Wextra -Wcast-qual -Wdeprecated -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wold-style-definition -Wpointer-arith -Wsign-compare -Wstrict-prototypes -Wundef -Wwrite-strings -Wno-packed-not-aligned -Wno-missing-field-initializers -D_GNU_SOURCE -fcommon -Werror -fPIC -march=armv8.1-a+crc+crypto -mcpu=thunderx2t99 -DALLOW_EXPERIMENTAL_API -DALLOW_INTERNAL_API -Wno-format-truncation -DCC_ARM64_NEON_PMULL_SUPPORT -MD -MQ 'lib/76b5a35@@rte_net@sta/librte_net_net_crc_neon.c.o' -MF 'lib/76b5a35@@rte_net@sta/librte_net_net_crc_neon.c.o.d' -o 'lib/76b5a35@@rte_net@sta/librte_net_net_crc_neon.c.o' -c ../lib/librte_net/net_crc_neon.c Looking at Luca env log: https://build.opensuse.org/build/home:bluca:dpdk/CentOS_8/aarch64/dpdk/_log [ 290s] [117/2414] cc -Ilib/76b5a35@@rte_net@sta -Ilib -I../lib -Ilib/librte_net -I../lib/librte_net -I. -I../ -Iconfig -I../config -Ilib/librte_eal/include -I../lib/librte_eal/include -Ilib/librte_eal/linux/include -I../lib/librte_eal/linux/include -Ilib/librte_eal/arm/include -I../lib/librte_eal/arm/include -Ilib/librte_eal/common -I../lib/librte_eal/common -Ilib/librte_eal -I../lib/librte_eal -Ilib/librte_kvargs -I../lib/librte_kvargs -Ilib/librte_telemetry/../librte_metrics -I../lib/librte_telemetry/../librte_metrics -Ilib/librte_telemetry -I../lib/librte_telemetry -Ilib/librte_mbuf -I../lib/librte_mbuf -Ilib/librte_mempool -I../lib/librte_mempool -Ilib/librte_ring -I../lib/librte_ring -fdiagnostics-color=always -pipe -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -O3 -include rte_config.h -Wextra -Wcast-qual -Wdeprecated -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wold-style-definition -Wpointer-arith -Wsign-compare -Wstrict-prototypes -Wundef -Wwrite-strings -Wno-packed-not-aligned -Wno-missing-field-initializers -D_GNU_SOURCE -fcommon -Werror -fPIC -mcpu=thunderxt88 -DALLOW_EXPERIMENTAL_API -DALLOW_INTERNAL_API -Wno-format-truncation -DCC_ARM64_NEON_PMULL_SUPPORT -MD -MQ 'lib/76b5a35@@rte_net@sta/librte_net_net_crc_neon.c.o' -MF 'lib/76b5a35@@rte_net@sta/librte_net_net_crc_neon.c.o.d' -o 'lib/76b5a35@@rte_net@sta/librte_net_net_crc_neon.c.o' -c ../lib/librte_net/net_crc_neon.c ...

My gut feeling is that there is some check missing in lib/librte_net/meson.build, maybe checking for __ARM_NEON in addition to the check on __ARM_FEATURE_CRYPTO? Thanks! -- David Marchand
