I recompiled the kernel now it's working fine. Now I have one more question. mplsadm tool contains proc support.but in mpls tool in proc, only spech_nh is there. In sysfs/mpls directory I have only debug and version files. Where can I get label,nhlfe entries Other than mpls show command.

The mpls command source code is a good basis if you want to know how to do it. But it might be easier to just parse the output of "mpls show"...

All of those 'files' have been removed. You can now get the same info with:
mpls ilm show
mpls nhlfe show
mpls labelspace show
mpls xc show

Did you compile it in or as a module? If it is as a module, you need to load the module.
