[dpdk-dev] DPDK libraries not compiling from source
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 cp: cannot stat ?/root/workspace/dpdk/x86_64-native-linuxapp-gcc/.config_tmp?: No such file or directory cp: cannot stat ?/root/workspace/dpdk/x86_64-native-linuxapp-gcc/.config_tmp?: No such file or directory make[5]: Nothing to be done for `depdirs'. Configuration done /root/workspace/dpdk/mk/rte.vars.mk:81: *** RTE_ARCH is not defined. Stop. make[2]: *** [all] Error 2 make[1]: *** [pre_install] Error 2 make: *** [install] Error 2 -- 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.
[dpdk-dev] basic forwarding example not working
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 Network devices using DPDK-compatible driver :00:0a.0 'Virtio network device' drv=igb_uio unused= :00:0b.0 'Virtio network device' drv=igb_uio unused= Network devices using kernel driver === :00:03.0 'RTL-8100/8101L/8139 PCI Fast Ethernet Adapter' if=ens3 drv=8139cp unused=igb_uio *Active* :00:08.0 'Virtio network device' if= drv=virtio-pci unused=igb_uio :00:09.0 'Virtio network device' if= drv=virtio-pci unused=igb_uio Other network devices = But when I run basic fowarding example from skeleton, I get following error ./basicfwd -c 1 -n 2 EAL: Detected lcore 0 as core 0 on socket 0 EAL: Support maximum 128 logical core(s) by configuration.
