[abhishek srivasatava]

hi
i am usng the linux-2.6.23-android-m3-rc20 kernel and  tool
chain
arm-2008q1-126-arm-none-linux-gnueabi.bin

while building the kernel i have found this error .............>

i am using  make goldfish_defconfig
 and make menuconfig and i am not copy the ".config" from the emulator
,is it necessory to copy the .config to build the kernel
i have solved that problem by applying add_pci_get_legacy_ide_irq.patch
and this patch solved that problem

now i am facing this problem--->
