Thanks Keith.
we will try to enable CentOS in our daily build test.
But I has a little concern about Ubuntu 14.
We enabled latest UB14 with kernel 3.13.0-24 at this may.
It seems that UB LTS will upgrade Linux kernel to 3.13.0-30.
But we don’t know when it upgrade, and it will cost a lot of effort to upgrade environment.
Can we indicate specific version for Ubuntu 14.04?
Btw, we met the same issue in RedHat 7.0 Beta version.

Someone compiling on CentOS kernel 3.13.7 needed the original code. Looks like some other type of ifdef change needs to be done to the kcompat.h file to allow it to compile on Ubuntu 14.04 with kernel 3.13.0-30.

Hi Keith,

we built the newest dpdk code on my machine, it seems OK,
please see UB14.04 info in my computer.
System:       Ubuntu14.04
Kernel:       3.13.0-24 X86_64
Compiler:     GCC 4.8.2 x86_64

Can you let me know which kernel version you use?

Apparently, it is this one: 3.13.0-30-generic, from uname -a


Thanks
Waterman
