[dpdk-dev] [Dpdk-pktgen]dpdk pktgen build failed on x86

[khemendra kumar]

Hi Keith,

Thanks for your quick help.

I am new to Pktgen and DPDK :(

Now I tried with DPDK18.02 version with Pktgen of 3.5.0 version.
This works on my x86 machine :)

Further I can use Pktgen 3.5.2 with DPDK 18.02. as you suggested.


Now I am trying *Pktgen on ARM machine*.
I am using *DPDK 18.02 and Pktgen3.5* stable.
But I met below error:
testuser at huawei-2:~/khem/VPP_Profile_setup/pktgen-3.5.0$ sudo make
RTE_SDK=/home/testuser/khem/VPP_Profile_setup/dpdk-stable-18.02.2
/home/testuser/khem/VPP_Profile_setup/dpdk-stable-18.02.2/mk/internal/
rte.extvars.mk:29: *** Cannot find .config in
/home/testuser/khem/VPP_Profile_setup/dpdk-stable-18.02.2/x86_64-native-linuxapp-gcc.
Stop.

I will check with Pktgen 3.5.2 also further.



Just to clarify my use case, I want to use *Pktgen as TG for send traffic
to VPP.*
*Both Pktgen and VPP will be running on 2 ARM machines (ARMv8).*


Thanks & Regards
Khem
