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
^
Documents/xen-4.1.2/xen/include/public/arch-x86/xen.h:43:5: note: in
expansion of macro ‘___DEFINE_XEN_GUEST_HANDLE’
___DEFINE_XEN_GUEST_HANDLE(const_##name, const type)
^
Documents/xen-4.1.2/xen/include/public/arch-x86/xen.h:44:41: note: in
expansion of macro ‘__DEFINE_XEN_GUEST_HANDLE’
#define DEFINE_XEN_GUEST_HANDLE(name) __DEFINE_XEN_GUEST_HANDLE(name,
name)
^
memory.c:242:13: note: in expansion of macro ‘DEFINE_XEN_GUEST_HANDLE’
DEFINE_XEN_GUEST_HANDLE(compat_memory_exchange_t);
Thank you

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. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

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