Hi, I am going through the kbuild process and found that at some stage after building vmlinux inside "/usr/src/linux/" somewhere kbuild uses objcopy to build bzImage inside /usr/src/linux/arch/i386/boot/compressed :- 1. objcopy -O binary -R .note -R .comment /usr/src/linux/vmlinux vmlinux.bin Here, kbuild removes .note and .comment sections from vmlinux before making vmlinux.bin. Could anyone please explain why we are creating binary image of vmlinux here. Basically, -O binary option creates a raw binary file which contains the memory dumps of the contents of the input object files. What is the purpose behind this ? objcopy with -O binary has been used in many places in kbuild process. Anyone please help me... Thanks in advance. Sumit.
