[Xenomai-help] Xenomai-2.4.2 vs kernel-2.6.24 (i686)

[Hubert Talbot]

Hi,

I try to build kernel 2.6.24 with adeos-ipipe-2.6.24-x86-2.0-03.patch
and I get this:

  ...
  AR      arch/x86/lib/lib.a
  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
arch/x86/kernel/built-in.o: In function `do_machine_check_vector':
ipipe.c:(.text+0x128de): undefined reference to `do_machine_check'
make[1]: *** [.tmp_vmlinux1] Erreur 1
make[1]: quittant le répertoire * /usr/src/linux-2.6.24 *
make: *** [debian/stamp-build-kernel] Erreur 2

real	7m59.559s
user	6m36.813s
sys	0m40.419s


Just to report the problem...

It's a 64bit symbol only it seems. Disable CONFIG_X86_MCE for now, will
fix. Thanks.
