Re: [dpdk-dev] Build failure on Ubuntu 14.04

BTW, he changed the value from 100 to 400 and that fixed his compile problem on CentOS.

The guy using CentOS stated if he changed the code to compare with KERNEL_VERSION(3,13,8) it works.

Also the compiler is older on CentOS gcc 4.4.7 and has a problem with the:
"--param max-inline-insns-single=100" issue in librte_eal/linuxapp/igb_uio/Makefile

Giving the error:
"error: inlining failed in call to 'kzalloc.clone.0': --param max-inline-insns-single limit reached" when compiling igb_uio.o

He suggested increasing the value to 1000, but he got that suggestion from stack overflow site.

I do not use CentOS and can not verify the issues or fix.

Thanks

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
