Subject: [dpdk-dev] Pktgen-DPDK build errors on ppc64le
Date: Tue, 28 Feb 2017 14:18:35 +0530 [thread overview]
Message-ID: <20170228084834.GB12546@chelsio.com> (raw)
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:
/root/pktgen-dpdk/lib/common/l2p.h: In function ‘pg_raw_dump_l2p’:
/root/pktgen-dpdk/lib/common/l2p.h:103:2: error: comparison is always true due to limited range of data type [-Werror=type-limits]
for (i = 0; i < RTE_MAX_LCORE; i++)
^
/root/pktgen-dpdk/lib/common/l2p.h:109:2: error: comparison is always true due to limited range of data type [-Werror=type-limits]
for (j = 0; j < RTE_MAX_LCORE; j++) {
^

/root/pktgen-dpdk/lib/common/l2p.h:486:2: error: comparison is always true due to limited range of data type [-Werror=type-limits]
for (lid = 0; lid < RTE_MAX_LCORE; lid++) {
^
/root/pktgen-dpdk/lib/common/l2p.c: In function ‘pg_port_matrix_dump’:
/root/pktgen-dpdk/lib/common/l2p.c:477:3: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
cnt.rxtx = get_map(l2p, pid, RTE_MAX_LCORE);
^
/root/pktgen-dpdk/lib/common/l2p.c:488:3: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
cnt.rxtx = get_map(l2p, pid, RTE_MAX_LCORE);
^
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
