I2C Build errors

I am using Quartus II 4.2, Nios II development kit 1.1 installation.

I was able to build the kernel and download successfully for

altera stratix development board.

Howerver when trying to build kernel with i2c support,

I am getting errors pasted below:

I have also included the .config file for your reference.

Looks like i have to initialise the na_i2c_* variables for my board.

Looks like the same needs to be done for na_uart_* variables.

Can you tell me whether there is a standard way of doing it, any header files,

Or how to do it

Any help will be appreciated
