Which linux-libc-headers are you using? 66539 2 liu.ming50 2016-09-23 07:45:53 +0000 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. 66575 3 liu.ming50 2016-09-26 07:13:17 +0000 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.
