10 # Copyright (c) 2004,2005 David H. Hovemeyer <daveho@cs.umd.edu>
14 # This is free software. You are permitted to use,
15 # redistribute, and modify it as specified in the file "COPYING".
17 # Required software to build GeekOS:
18 # - GNU Make (http://www.gnu.org/software/make)
19 # - gcc 2.95.2 generating code for target (i386/ELF) and host platforms
20 # - Perl5, AWK (any version), egrep
22 # Cygwin (http://cygwin.com) may be used to build GeekOS.
23 # Make sure that gcc, binutils, nasm, and perl are installed.
26 # - This makefile has been written carefully to work correctly
27 # with the -j (parallel make) option. I regularly use "make -j 2"
28 # to speed the build process on 2 processor systems.
31 # Base address of kernel
33 # Note: at top of memory minus three pages (GDT/TSS/IDT)
37 # Note that the code will initially load at 0x10000
39 # The setup code needs to copy it up to this address and jump there
