[Buildroot] Error while building libevas, SFD_NONBLOCK undeclared

[Daniel.]

I'm receiving this error while trying to build with buildroot.

make[5]: Entering directory
`/home/hilst/buildroot/buildroot-2013.05/output/build/libevas-1.7.4/src/bin'
CC evas_cserve2_main_loop_linux.o
evas_cserve2_main_loop_linux.c: In function '_signalfd_setup':
evas_cserve2_main_loop_linux.c:156: error: 'SFD_NONBLOCK' undeclared (first
use in this function)
evas_cserve2_main_loop_linux.c:156: error: (Each undeclared identifier is
reported only once
evas_cserve2_main_loop_linux.c:156: error: for each function it appears in.)
evas_cserve2_main_loop_linux.c:156: error: 'SFD_CLOEXEC' undeclared (first
use in this fu

My .config can be found here: https://gist.github.com/gkos/5950964

Any help is appreciated,

I'm on archilinux using Sourcery CodeBench toolchain..
Best regards

The signalfd(2) man page says that these flags (SFD_NONBLOCK and SFD_CLOEXEC) 
are only defined since kernel version 2.6.27. It seems that your toolchain 
uses an older kernel. Which version of the Sourcery CodeBench do you use?

Hi Daniel,

Please Cc the list on your response.

Yes. Apparently the 2009q1 toolchain is based on kernel version 2.6.30 which 
should be fine, but for some reason it does not have SFD_NONBLOCK and 
SFD_CLOEXEC in its sys/signalfd.h header file. 2010q1 (2.6.36 based) does have 
these defines. Both toolchains are quite old anyway.
