xv6 is a re-implementation of Dennis Ritchie's and Ken Thompson's Unix
|
|
|
|
|
Version 6 (v6). xv6 loosely follows the structure and style of v6,
|
|
|
|
|
but is implemented for a modern x86-based multiprocessor using ANSI C.

BUILDING AND RUNNING XV6
|
2006-09-07 20:06:20 +00:00
|
|
|
|
|
|
|
|
To build xv6 on an x86 ELF machine (like Linux or FreeBSD), run "make".
|
|
|
|
|
On non-x86 or non-ELF machines (like OS X, even on x86), you will
|
|
|
|
|
need to install a cross-compiler gcc suite capable of producing x86 ELF
|
2014-08-28 21:28:40 +00:00
|
|
|
binaries. See http://pdos.csail.mit.edu/6.828/2014/tools.html.
|
2006-09-07 20:06:20 +00:00
|
|
|
Then run "make TOOLPREFIX=i386-jos-elf-".
|
|
|
|
|
|
2014-08-28 21:28:40 +00:00
|
|
|
To run xv6, install the QEMU PC simulators. To run in QEMU, run "make qemu".

|
|
|
|
2010-09-02 07:25:33 +00:00
|
|
|
To create a typeset version of the code, run "make xv6.pdf". This
|
|
|
|
|
requires the "mpage" utility. See http://www.mesa.nl/pub/mpage/.
