Re: [ovs-discuss] Cannot link with dpdk

Tue, 29 Mar 2016 03:11:14 -0700

thanks for your prompt reply but changing the path-to-dpdk does not bring any breakthrough.
 
I am able to run helloworld example ,provided in DPDK thus I don't see any issue with DPDK installation.

I was analying the config.log file and found that undefined reference to libpcap.so and libpthread.so . To resolve them I have added -lpcap in acinclude.m4 file as below-

DPDKLIBS ="-ldpdk -lpcap"

which resolved the undefined reference to libpcap.so but original problem is as it is.

Any suugestion?

Thanks & Regards
Vivek

Set my path-to-dpdk to homedirectory/dpdk2.2/ x86_64-ivshmem-linuxapp-gcc and this should resolve your issue.

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.

To be mention that I have install DPDK2.2 as below

  1. make config T=x86_64-ivshmem-linuxapp-gcc
  2. make install T= x86_64-ivshmem-linuxapp-gcc DESTDIR=install

my path-to-dpdk = homedirectory/dpdk2.2/install/share/dpdk.

 

Please suggest.

 

Thanks & Regards

Vivek

Do you see DPDK library in the path mentioned path-to-dpdk/x86_64-ivshmem-linuxapp-gcc/lib/libdpdk.a?

Hi


I am trying to configure OVS 2.5 with DPDK 2.2 with following option 

./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var –with-dpdk=path-to-dpdk-/x86_64-ivshmem-linuxapp-gcc/ --enable-ssl
 
but I get error message "configure: error: cannot link with dpdk"
 


You need to have CONFIG_RTE_BUILD_COMBINE_LIBS=y while building dpdk.

Gowrishankar
