Acronis agent installation on Ubuntu Server 13.10 x64

Hi,

I am trying to install the ABR 11 agent on to Ubuntu Server 13.10 x64. The kernel version of this server is 3.11.0-20.

The installation has completed and the machine has been successfully registered on the management server. The SnapAPI version is 2.6 and the compilation of this module failed during the agent install. My attempt to compile the module manually also failed.

The command used was;
dkms build -m snapapi26 -v 0.7.64 --config /boot/config-3.11.0-20-generic --arch x86_64

The dkms log is;
------------------------------------------------------------------------------------------

Is the SnapAPI module supported on this kernel?

Are there other steps I can take to get the SnapAPI module compiled?

Thank you for your help and advice.
