Re: conflicting types for "netdev_features_t"; netdevice.h:854: note: previous declaration of "netdev_features_t" was here

16/01/2014 18:16, TSADOK, Shlomi (Shlomi):

When compiling DPDK-1.5.2-2 I'm getting the below error
OS is CentOS 6.5, kernel is 2.6.32-431.3.1.el6.x86_64

Any idea what the issue is?

I think you are not using the latest version.
This commit should be the needed in your case:
