CUDA SDK 2.2 missing include file? Problem doing make on SDK 2.2

guys after a few days of headache,finally installed all the above libraries…had to go through a lot of troubles to get everything in place.

but when i compile the SDK examples, its giving new error…

/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory

can someone tell me what’s that…

im using kubuntu 9.04, 64 bit version…why do i need this 32 bit file???
