[dpdk-dev] basic forwarding example not working

[Subbu CS]

I am using two virtio network adapter on VM on KVM host.

As  in following output, I have bound both interface with igb_uio driver

./dpdk_nic_bind.py --bind=igb_uio 00:0a.0
./dpdk_nic_bind.py --bind=igb_uio 00:0b.0

[root at localhost tools]# ./dpdk_nic_bind.py --status

But when I run basic fowarding example from skeleton, I get following error

[dpdk-dev] DPDK libraries not compiling from source

[Subbu CS]

Hi all,

I tried compiling DPDK from source using setup.sh script in tools
directory, but I get this error

[32] Remove KNI module
[33] Remove hugepage mappings

[34] Exit Script

Option: 14

/bin/sh: line 1: cc: command not found

--
 RTE_TARGET exported as x86_64-native-linuxapp-gcc

Then, I set RTE_ARCH=x86_64 manually, but it did not work

please suggest appropriate way to compile DPDK libraries.
