[Xen-users] problem of installing tpm emulator in Xen

["mars" <mars208@xxxxxxx>]

I want to install tpm emulator simulating the TPM hardware in Xen platform. But 
compiling tpm emulator brings such error.My kernel is 2.6.16.
#make ; make install
.........
  Building modules, stage 2.
  MODPOST
*** Warning: "__stack_chk_fail" 
[/root/xen-3.0.2/tools/vtpm/tpm_emulator/tpm_emulator.ko] undefined!
  CC      /root/xen-3.0.2/tools/vtpm/tpm_emulator/tpm_emulator.mod.o
  LD [M]  /root/xen-3.0.2/tools/vtpm/tpm_emulator/tpm_emulator.ko

inserting module into linux kernel have following errors:
#modprobe tpm_emulator startup="clear"
FATAL: Error inserting tpm_emulator 
(/lib/modules/2.6.16-xen/extra/tpm_emulator.ko): Unknown symbol in module, or 
unknown parameter (see dmesg)

in file /var/log/message
last error line is :
Oct 30 13:56:36 localhost kernel: tpm_emulator: Unknown symbol __stack_chk_fail

I have tried serveral ways, installing high version tpm emulator, patching the 
16K stack size, adding the compiling flag -fno-stack-protector, but still the 
same result.How can I solve the problem.
