Hi All,
We are seeing Pktgen-DPDK not building on ppc64le with latest dpdk git
repo.
Below build errors are seen:
-------------------------
[pktgen-dpdk]# make
== lib
== common
CC l2p.o
In file included from /root/pktgen-dpdk/lib/common/l2p.c:88:0:

cc1: all warnings being treated as errors
make[3]: *** [l2p.o] Error 1
make[2]: *** [all] Error 2
make[1]: *** [common] Error 2
make: *** [lib] Error 2
-------------------------
By changing CONFIG_RTE_MAX_LCORE to 128 in defconfig_ppc_64-power8-linuxapp-gcc
file, Pktgen-DPDK then builds fine.
Thanks,
Rahul
