I encountered following errors when build libnl with musl:

Comment 1 Richard Purdie 2016-09-22 14:52:18 UTC 
I think we ran into this when upgrading to the new kernel and I refreshed the linux-libc-headers to resolve it. Which linux-libc-headers are you using?
Comment 2 Ming Liu 2016-09-23 07:45:53 UTC 
I was building it with a linux 4.6 kernel(git://github.com/Freescale/linux-fslc.git), plus the following patches back-ported from linux-libc-headers 4.8 recipe:
 
SRC_URI_append_libc-musl = "\
    file://0001-libc-compat.h-fix-some-issues-arising-from-in6.h.patch \
    file://0002-libc-compat.h-prevent-redefinition-of-struct-ethhdr.patch \
    file://0003-remove-inclusion-of-sysinfo.h-in-kernel.h.patch \
   "
 
when I encountered that libnl compiling issue, but as you said, I might have done something wrong in my building environment, so I can double test it, will let you know if I find something new.
Comment 3 Ming Liu 2016-09-26 07:13:17 UTC 
Hi,

I just re-tested it with the linux-libc-headers 4.8, the problem is not present with that, so maybe it's caused my wrong environment.

I am closing it, sorry for the noise.
