Re: [ovs-discuss] Cannot link with dpdk

[Vivek Gupta]

Initially I had tried with with-dpdk= homedirectory/dpdk2.2/install/share/dpdk/x86_64-native-linuxapp-gcc but nothing happened. then switched to with-dpdk=homedirectory/dpdk2.2/ x86_64-ivshmem-linuxapp-gcc but problem is as it is. Did I commited any wrong step in DPDK installations? My steps are as below- untar dpdk-2.2.0.tar.gz Changed following configuration variable in config/common_linuxapp CONFIG_RTE_BUILD_COMBINE_LIBS=y CONFIG_RTE_LIBEAL_USE_HPET=y CONFIG_RTE_BUILD_SHARED_LIB=y CONFIG_RTE_RING_SPLIT_PROD_CONS=y CONFIG_RTE_LIBRTE_PMD_PCAP=y make config T=x86_64-ivshmem-linuxapp-gcc make install T=x86_64-ivshmem-linuxapp-gcc DESTDIR=install export RTE_SDK=‘<homedirectory>/dpdk2.2/install/share/dpdk Compiled and run "HelloWorld" example. untar openvswitch-2.5.0.tar.gz ./boot.sh and start running configuration. Initially I was building DPDK as below steps- make config T=x86_64-ivshmem-linuxapp-gcc make && make install After make install step I was getting error "Cannot install DPDK with T defined and DESTDIR undefined" By taking help from forums I changed my "make install" step as "make install x86_64-ivshmem-linuxapp-gcc DESTDIR=install" I am stuck in OVS configuration with DPDK. Please suggest.

When one use install target ‘x86_64-ivshmem-linuxapp-gcc’ the directory layout is slightly different.   make install T= x86_64-ivshmem-linuxapp-gcc DESTDIR=install creates  ‘<homedirectory>/dpdk2.2/install/share/dpdk/ x86_64-native-linuxapp-gcc`, where as one expects the directory layout to be ‘<homedirectory>/dpdk2.2/install/share/dpdk/ x86_64-ivshmem-linuxapp-gcc`.   This is the reason the OVS configure was failing in your case. Try passing –with-dpdk= homedirectory/dpdk2.2/install/share/dpdk/x86_64-native-linuxapp-gcc (or)  --with-dpdk=homedirectory/dpdk2.2/ x86_64-ivshmem-linuxapp-gcc   Regards, Bhanu Prakash.   From: discuss [mailto:discuss-boun...@openvswitch.org] On Behalf Of Bodireddy, Bhanuprakash Sent: Tuesday, March 29, 2016 10:31 AM To: Vivek Gupta <vive...@hcl.com>; gowrishankar <gowrishanka...@linux.vnet.ibm.com> Cc: discuss@openvswitch.org Subject: Re: [ovs-discuss] Cannot link with dpdk   Set my path-to-dpdk to homedirectory/dpdk2.2/ x86_64-ivshmem-linuxapp-gcc and this should resolve your issue.   Regards, Bhanu Prakash.   From: Vivek Gupta [mailto:vive...@hcl.com] Sent: Tuesday, March 29, 2016 10:15 AM To: Bodireddy, Bhanuprakash <bhanuprakash.bodire...@intel.com>; gowrishankar <gowrishanka...@linux.vnet.ibm.com> Cc: discuss@openvswitch.org Subject: RE: [ovs-discuss] Cannot link with dpdk   Yes, I am able to see libdpdk.so file in path-to-dpdk/x86_64-native-linuxapp-gcc/lib Please find attached config.log file.
