kernel compilation Ubuntu Server 12.04 Error 2

[d80k]

Hi
I'm fighting for a few days to compile the kernel in Ubuntu 12.04 and appending grsecurity patch. I tried a few instructions from the net.
I tried to download a new kernel from kernel.org and sources. Compilation always ends in the following error:

*** End of the configuration.
*** Execute ‘make’ to start the build Or try ‘make help’
dk@dk:~/linux-3.2.0$ sudo make

make [1]: Nothing to be done for `relocs'.

what is it? I do not understand what this error means?

please help
