OK, I tried building on kernel 4.6.0 from jessie-backports. The FATAL 
errors are gone but, the syntax errors in the g-i compile stage are 
still being thrown:


  .../sysroot-target/usr/include/glib-2.0/gio/gio-autocleanups.h:106:
  syntax error, unexpected typedef-name, expecting identifier or '(' in
  'typedef GProxy *GProxy_autoptr;' at 'GProxy_autoptr'

...although they don't seem to affect the build, since g-i now 
targetinstalls correctly :)



You could hack ./platform-arm-hf/sysroot-cross/bin/qemu-cross to add '-r
3.18' to the qemu command-line. That may help, but could cause other issues
later, but probably not for the g-i stuff.


Uhh, that seems more like a dirty hack than a real fix to me ;-) I'll 
rather compile with a newer host kernel.


Thanks!

I don't know how to find out the minimum required kernel version for a
compiled glibc but I looked at the configure options used for
OSELAS.Toolchain-2016.06.0. The minimum required kernel version is set to
3.18 :-/.

You could hack ./platform-arm-hf/sysroot-cross/bin/qemu-cross to add '-r
3.18' to the qemu command-line. That may help, but could cause other issues
later, but probably not for the g-i stuff.

Btw, that script is generated in rules/host-qemu.make if you want to create
a more permanent solution.

This may be a glibc issue: When executed like this, then the target glibc
will see your host kernel version. What toolchain are you using? The
minimum kernel version for the glibc is selected at build time and verified
at runtime. So your host kernel may indeed be to old for the target
toolchain...

The ldd script only prints "FATAL: kernel too old" and exits with return 
code 1 when called on platform/root/bin/sh.  I have attached the script. 
 The error actually comes from the call to qemu-cross in line 116, 
which I can reproduce:


$ ./sysroot-cross/bin/qemu-cross -E \
  LD_TRACE_LOADED_OBJECTS=1,LD_WARN=,LD_BIND_NOW=,LD_VERBOSE= \
  root/bin/sh
FATAL: kernel too old

I'm currently rebuilding my project in a new, clean directory to see if 
the error goes away.

I don't think the Kernel Version matters. I think the errors are caused by
a broken cross ldd. Please test check if .../sysroot-cross/bin/qemu/ldd
works correctly for target binaries. If not, then please send this file,
it's a shell script.
