[dpdk-users] KNI on 32 bit

[Nishant Verma]

Hi All,

My machine is 64 bit.
I am trying to compile DPDK 16.07 with i686. It's giving me error :
*"/cm_data/onewebcommon/data_fw/hfdp/script/intel-dpdk/lib/librte_port/rte_port_kni.c:38:21:
fatal error: rte_kni.h: No such file or directory"*

Little bit of reading of previous question indicated  that in .config i
need to set the *CONFIG_RTE_LIBRTE_KNI=y* manually.

I tried that too, but still getting same error.

Any clue??????? to resolve the issue.

See this config template:
	http://dpdk.org/browse/dpdk/tree/config/defconfig_i686-native-linuxapp-gcc#n45
"KNI is not supported on 32-bit"

You should not see this error. See the makefile:
	http://dpdk.org/browse/dpdk/tree/lib/librte_port/Makefile#n59
ifeq ($(CONFIG_RTE_LIBRTE_KNI),y)
SRCS-$(CONFIG_RTE_LIBRTE_PORT) += rte_port_kni.c
endif

And CONFIG_RTE_LIBRTE_KNI must be disabled for 32-bit.

But i am persuaded by this link.
http://dpdk.org/ml/archives/dev/2014-January/001143.html

If it really can't, then some one has to dismiss this as well.
