Compilation Error in tools (BIOS/hvmloader)

Compilation Error in tools (BIOS/hvmloader)

[Emre Erenoglu]

Hi,

I just recognised a compilation error which prevents the system from
creating hvmloader files in necessary places. It does not stop overall
compilation so I wanted to write this here in case developers might
not be aware of the problem.

Here's the output when compiling latest unstable code (15/2/2007):

emre@xen:/xen/xen-unstable.hg/tools$ sudo make clean
emre@xen:/xen/xen-unstable.hg/tools$ sudo make all
...
...
...
...
gcc   -m32 -march=i686 -DNDEBUG -std=gnu99 -Wall -Wstrict-prototypes

There are undefined symbols in the BIOS:

Best regards,

On Ubuntu or Gentoo? You'll have to add the option -fno-stack-protector
to gcc. make CC='gcc -fno-stack-protector' should do it.

I thought the developers added a check for that option some time ago,
maybe they missed some places.

This issue is fixed in current xen-unstable.
