I2C Build errors

[Altera_Forum]

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   Errors:  drivers/i2c/.i2c-core.o.d: done.  CC drivers/i2c/algos/i2c-algo-oc.o /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/algos/i2c-algo-oc.c: In function `i2c_oc_add_bus': /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/algos/i2c-algo-oc.c:385: warning: unused variable `oc_adap' drivers/i2c/algos/.i2c-algo-oc.o.d: done.  LD drivers/i2c/algos/built-in.o  CC drivers/i2c/busses/i2c-oc.o /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:164: error: `na_i2c_0' undeclared here (not in a function) /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:164: error: initializer element is not constant /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:164: error: (near initialization for `oc_hw_0.base') /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:165: error: `na_i2c_0_irq' undeclared here (not in a function) /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:165: error: initializer element is not constant /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:165: error: (near initialization for `oc_hw_0.irq') /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:170: error: `na_i2c_1' undeclared here (not in a function) /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:170: error: initializer element is not constant /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:170: error: (near initialization for `oc_hw_1.base') /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:171: error: `na_i2c_1_irq' undeclared here (not in a function) /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:171: error: initializer element is not constant /cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x/drivers/i2c/busses/i2c-oc.c:171: error: (near initialization for `oc_hw_1.irq') make[4]: *** [drivers/i2c/busses/i2c-oc.o] Error 1 make[3]: *** [drivers/i2c/busses] Error 2 make[2]: *** [drivers/i2c] Error 2 make[1]: *** [drivers] Error 2 make: *** [_all] Error 2 make: Leaving directory `/cygdrive/c/altera/kits/nios2/bin/eclipse/plugins/com.microtronix.nios2linux.kernel_0.1.5/linux-2.6.x'
