The old Linux kernel source ver 0.11 which has been tested under modern Linux, Mac OSX and Windows.

##1. Build on Linux

##1.1. Linux Setup

• a linux distribution: debian , ubuntu and mint are recommended
• some tools: gcc gdb qemu
• a linux-0.11 hardware image file: hdc-0.11.img, please download it from http://www.oldlinux.org, or http://mirror.lzu.edu.cn/os/oldlinux.org/, ant put it in the root directory.

##1.2. hack linux-0.11

$ make help		// get help
$ make  		// compile
$ make start		// boot it on qemu
$ make debug		// debug it via qemu & gdb, you'd start gdb to connect it.

$ gdb tools/system
(gdb) target remote :1234
(gdb) b main
(gdb) c

##2. Build on Mac OS X

##2.1. Mac OS X Setup

• install cross compiler gcc and binutils
• install qemu
• install gdb. you need download the gdb source and compile it to use gdb because port doesn't provide i386-elf-gdb, or you can use the pre-compiled gdb in the tools directory.
• a linux-0.11 hardware image file: hdc-0.11.img

$ sudo port install qemu
$ sudo port install i386-elf-binutils i386-elf-gcc

optional

$ wget ftp://ftp.gnu.org/gnu/gdb/gdb-7.4.tar.bz2
$ tar -xzvf gdb-7.4.tar.bz2
$ cd gdb-7.4
$ ./configure --target=i386-elf
$ make

##2.2. hack linux-0.11

same as section 1.2
