Hi,
Is there anyone who tried compiling VPP with GCC 7?
There's fall-through warning from DPDK code, but there's already FALLTHROUGH
comments in DPDK code to suppress the warning and -Wimplicit-fallthrough=2 in
DPDK makefile, but somehow I'm still getting the warnings when compiling VPP.
I have to add an option of -Wimplicit-fallthrough=0 or
-Wno-implicit-fallthrough to get the compiling pass, but it seems unreasonable.
gcc -Wp,-MD,./.ark_ethdev_rx.o.d.tmp -pie -fPIC -pthread
-march=armv8-a+crc+crypto -DRTE_MACHINE_CPUFLAG_NEON
-DRTE_MACHINE_CPUFLAG_CRC32 -DRTE_MACHINE_CPUFLAG_AES
