Build failed in step 'Installing C library headers & start files'

[andrewminkin]

Dear CT-NG mailing list,

can anyone help with this errror ?

Target Setup
The target is running this kernel:
Linux raspberrypi 4.1.15+ #830 Tue Dec 15 16:58:28 GMT 2015 armv6l 
GNU/Linux

Build PC Setup
i've unpacked the tarball for 4.1.15+  to this directory on the build 
pc :
/home/user/cross/linux-853eff4e9b369cdc20be7c538bc5a5291eeab31d

The build pc native compiler is gcc 5.2.0, running under
Linux localhost 2.6.23.9lw #105 SMP PREEMPT Fri Jun 27 18:56:59 EDT 
2008 i686 i686 i386 GNU/Linux

CT-NG Setup
in ct-ng menuconfig i've set
    Target OS (linux)  --->
             Linux kernel version (custom tarball or directory)  --->
             custom tarball or directory
             
(/home/user/cross/linux-853eff4e9b369cdc20be7c538bc5a5291eeab31d)
and
C library (glibc)  --->  extra config
--with-headers=/home/user/cross/linux-853eff4e9b369cdc20be7c538bc5a5291eeab31d 
--srcdir=/home/user/cross/linux-853eff4e9b369cdc20be7c538bc5a5291eeab31d

obviously CT-NG can't find include/features.h though i can see files by 
that name under :

/home/user/cross/linux-853eff4e9b369cdc20be7c538bc5a5291eeab31d/include/xen/features.h
/home/user/cross/linux-853eff4e9b369cdc20be7c538bc5a5291eeab31d/include/xen/interface/features.h
/home/user/cross/linux-853eff4e9b369cdc20be7c538bc5a5291eeab31d/include/sched/features.h

is it looking for this file from the target kernel at this stage ?


thanks for any assistance !

Andrew
