Re: [vpp-dev] VPP 19.01 + SPDK

2019-01-02 Thread Florin Coras 
Hi Ram, 

Tomasz cc'ed, amongst others, have been working on integrating SPDK with VPP's 
host stack. Maybe the patch here [1] can provide some answers.

[vpp-dev] VPP 19.01 + SPDK

2019-01-02 Thread Ramaraj Pandian 
Hello,

I am new to VPP and trying to integrate VPP with SPDK. I see old VPP version 
generates .a files as well along with .so files which were useful to SPDK with. 
But latest version, it generates only .so files, I tried to change 
/src/cmake/library.cmake to build static library as well but build fails:

: && ccache /opt/rh/devtoolset-7/root/bin/cc -march=corei7 -mtune=corei7-avx -g

Can someone shed light on this?
