[Qemu-discuss] qemu-timer.c and ivshmem.c compiling error

[Muhammad Asif]

Hi Geeks,

We intend to use KVM with libvmi for VM introspection. libvmi provide a patch to get this functionality with KVM.

I downloaded qemu-kvm-0.14.0/ and patch it respectively and them try to compile as following link. 

https://github.com/libvmi/libvmi/tree/master/tools/qemu-kvm-patch

But during make I am facing following errors.

 LINK  x86_64-softmmu/qemu-system-x86_64

collect2: error: ld returned 1 exit status

make[1]: *** [qemu-system-x86_64] Error 1

make: *** [subdir-x86_64-softmmu] Error 2

I tried to compile it without patch but issue is same qemu-timer.c is creating problems.

What issue can be.

Thanks.
