[Buildroot] Bug 3877 - Patch not working

[inblueswithu]

Hi,

I 've got *"undefined reference to `accept4'"* this error while using 
buildroot.
When I googled, I got this patch: 
https://bugs.uclibc.org/attachment.cgi?id=3415&action=edit

I tried to apply this patch manually to the file as the patch is failing 
to apply.
Even then the error persisted.
Can some one please help me in overcoming this.
My uClibc version : uClibc-0.9.32 & This was the error in command line

    cd src/network/ && /usr/bin/make -f Makefile
    make[2]: Entering directory
    `/home/inblueswithu/buildroot2/buildroot/output/build/qt-4.7.4/src/network'

Can you please post your Buildroot .config file?

Thanks,

Please look into it.

uClibc will only add an accept4() function if your kernel headers expose
sys_accept4, which for ARM was only added in 2.6.36.

Make sure your kernel headers (and runtime kernel) is atleast 2.6.36.

According to his .config file, the kernel headers used were 2.6.35, so
I guess you found the right spot.

Thank You for your reply. This might be the problem, I'm working on this 
right now.
