Hi Andy,
Thanks for the reply.
I've downloaded and built the kernel:
git clone git://git.openmoko.org/git/kernel.git linux-2.6
cd linux-2.6
git checkout -b mystable origin/andy-tracking
mkdir GTA02
cp arch/arm/configs/gta02-moredrivers-defconfig GTA02/.config
cp arch/arm/configs/gta02-moredrivers-defconfig .config
./build GTA02 dummy
When I try to run the make command line that you've provided, I get the
following error:
r...@notebook:~/OpenMoko2/linux-2.6# make ARCH=arm -C
/home/wesjin/OpenMoko2/linux-2.6/
KBUILD_SRC=/home/wesjin/OpenMoko2/linux-2.6/ M=`pwd`
make: Entering directory `/home/wesjin/OpenMoko2/linux-2.6'
ERROR: Kernel configuration is invalid.
include/linux/autoconf.h or include/config/auto.conf are missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.
WARNING: Symbol version dump
/home/wesjin/OpenMoko2/linux-2.6/Module.symvers
is missing; modules will have no dependencies and modversions.
CC kernel/bounds.s
cc1: error: include/linux/autoconf.h: No such file or directory
make[1]: *** [kernel/bounds.s] Error 1
make: *** [_module_/home/wesjin/OpenMoko2/linux-2.6] Error 2
It's complaining that the kernel has not been configured. However, I've
copied the gta02_moredrivers_defconfig
file to GTA02 and to linux-2.6 directory. Do I need to do anything else? Is
there someway that I can generate
or copy autoconf.h from somewhere?
Thanks for your help.
Wesley
