Hi All, Hopefully this will help demystify the build process Notation: <primary input file> (<file size in bytes>) | + <additional input file> | * <command> | \-> <output file> (<file size in bytes>) The file sizes are arbitrary and are based on the current configuration options I have set for a small kernel. They are simply there to illustrate the relative differences in file sizes.Great! Thanks for sharing this.
Your welcome :)

Note that vmlinux.o is not used to generate bzImage but I've included it for completeness[...]quoted
+ net/built-in.o | * ld -m elf_i386 -r -o vmlinux.o | \->vmlinux.o (2,889,050)What is the purpose of vmlinux.o then?
I don't know - Anyone? Regards, Graeme
