[ptxdist] Udev 172/181 doesn't find ptxdist kernel headers and fails to compile

[Íñigo López-Barranco]

Hello all.

I'm trying to build ptxdist-2012.04.0 but it fails to compile using both 
versions of udev complaining about some undeclared defines:

src/libudev-monitor.c: In function 'udev_monitor_new_from_socket':
src/libudev-monitor.c:153: error: 'SOCK_NONBLOCK' undeclared (first use 
in this function)
src/libudev-monitor.c:153: error: (Each undeclared identifier is 
reported only once
...

Searching in the list's archives found this message with a patch adding 
the kernel headers path to the udev rules for toolchains without kernel 
headers (or old ones):

http://thread.gmane.org/gmane.comp.embedded.ptxdist.devel/7997/focus=8140

I've checked that this is already included in my udev.make file, that 
I've selected the kernel headers (2.6.39) in ptxdist menu and that 
SOCK_NONBLOCK and other missing defines are present in the kernel 
headers, so I don't know what else to check now.

The gcc version is 4.3.2 and the platform is x86 (586).

Thanks in advance

And the glibc version? I think you need support for the NONBLOCK stuff from
there too.

Re: [ptxdist] Udev 172/181 doesn't find ptxdist kernel headers and fails to compile

[Íñigo López-Barranco]

You are right: SOCK_NONBLOCK and SOCK_CLOEXEC are only available on 
kernel >= 2.6.28 & glibc >= 2.9, and the glibc version in my toolchain 
(OSELAS 1.99.3) is 2.8.
I'm going to upgrade the toolchain and try again.
Thank you!
