Kernel compile time error

Hi ,
I am new to UDOO board, I am having UDOO-DualLite.

I am trying to compile kernel with my installed cross compiler on ubuntu13.04.

I had followed these steps.

1. make ARCH=arm UDOO_defconfig
2. make ARCH=arm menuconfig
3. make -j4 CROSS_COMPILE=arm-linux-gnueabihf- ARCH=arm uImage modules

But in this process i am getting this error.

make[2]: *** No rule to make target `drivers/rtc/class.o', needed by `drivers/rtc/rtc-core.o'. Stop.
make[1]: *** [drivers/rtc] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [drivers] Error 2

I have tried to debug the issue, and i found this file class.c is present in /drivers/base directory and makefile(/drivers/rtc/) is importing class.o but not able to import.

any help will be deeply appreciated to resolve my issue.

thank you

 

hi delba,

this time i tried with Freescale cross compiler also, still i am getting same error as mentioned above.

i have seen makefile of drivers/rtc/ directory their it is mentioned like that,

ccflags-$(CONFIG_RTC_DEBUG) := -DDEBUG
obj-$(CONFIG_RTC_LIB) += rtc-lib.o
obj-$(CONFIG_RTC_HCTOSYS) += hctosys.o
obj-$(CONFIG_RTC_CLASS) += rtc-core.o
rtc-core-y := class.o interface.o

but their is no class.c file in this directory, i tried to find this source file and i found it in /drivers/base/ directory and i copied it in /drivers/rtc/ , but i gets error msgs of multiple definition.

Hi,

i think you should use the full path:
CROSS_COMPILE=/home/udoo/udoo-dev/arm-fsl-linux-gnueabi/bin/arm-fsl-linux-gnueabi-
so
CROSS_COMPILE=/home/<YOUR_PATH>/arm-fsl-linux-gnueabi/bin/arm-fsl-linux-gnueabi-
