Xen devel - Apr 2007 - compilation fails with __stack_check_fail in xen-3.0.4

Hi All,

I downloaded the xen-3.0.4 source from xensource site and compiled it from
source.

On giving a make world , the make fails after almost finishing the
compilation.
The error i got is -

init/built-in.o: In function `try_name'':
do_mounts.c:(.text+0x5f3): undefined reference to `__stack_chk_fail''
init/built-in.o: In function `name_to_dev_t'':

init/built-in.o: In function `change_floppy'':

init/built-in.o:initramfs.c:(.init.text+0x4d73): more undefined references
to `__stack_chk_fail'' follow
make[4]: *** [.tmp_vmlinux1] Error 1
make[4]: Leaving directory `/opt/xen-3.0.4_1-src/linux-2.6.16.33-xen''

make[2]: *** [linux-2.6-xen-install] Error 2
make[2]: Leaving directory `/opt/xen-3.0.4_1-src''
make[1]: *** [install-kernels] Error 1

I am not able to understand the error messages and their intended purpose in
built-in.o .
Also i am not able to find the __stack_chk_fail being referred from any of
these functions.
Are these some linker specific symbols or similar?

Please note i am running Ubuntu6.10 Edgy Eft.
GCC 4.1
Kernel 2.6.20.1 (This is not required i guess)

Somehow i suspect gcc4.1 is playing the spoilsport here. :-(

Any help?

Thanks

Right, your gcc sets by default the stack-protector flag. You have to
manually disable it by editing some makefiles.
According to my experience you have add "-fno-stack-protector" to the
CFLAGS within all of the following files:

Config.mk
pristine-linux-2.6.16.33/Makefile
ref-linux-2.6.16.33/Makefile
linux-2.6.16.33-xen/Makefile
linux-2.6-xen-sparse/arch/<your architecture>/Makefile

-fno-stack-protector  ran in to it with my x86_64 system.  since 4.1 has ssp it
has to be turned off for the kernel as i under stand it.
