Xen error

Xen error

[aoa033]

Hi,

I am a final year student interested in learning more about virtualization
and Xen. I have been trying to build and install Xen 4.1.2 from source
however I am getting the following error which I do not know how to fix.
Could anyone be of assistance

The error is: 

memory.c: In function ‘compat_memory_op’:
Documents/xen-4.1.2/xen/include/public/arch-x86/xen.h:35:33: error:
typedef ‘__guest_handle_const_compat_memory_exchange_t’ locally defined
but not used [-Werror=unused-local-typedefs]
     typedef struct { type *p; } __guest_handle_ ## name
                                 ^

memory.c:242:13: note: in expansion of macro ‘DEFINE_XEN_GUEST_HANDLE’
             DEFINE_XEN_GUEST_HANDLE(compat_memory_exchange_t);

Thank you

Have you modified the source yourself?

This looks like you have added a new guest handle in a function but not
referenced it.

Also, Xen 4.1.2 is very old.  Try using a newer version of Xen.

Do not drop xen-devel from the CC list, please.

Unless you can reproduce the issue on a supported version of Xen, there
is next to nothing anyone can do to help.

At the very least you should argue to be use the latest 4.1.x, which is
4.1.6.1.

The fix is in 4.1.5 onwards.
