8 To obtain the Plan 9 tree, use CVS
11 or download a tar file from

14 In the root of the tree, run
16 This script first uses
18 to build the Plan 9 build program
21 It cleans all previously built object files and libraries out of the tree,
22 rebuilds and installs everything, and then cleans up.
24 There are a few files in tree which have the root
28 edits these files to replace the string
30 with the name of the root of the current tree.
34 builds an HTML version of the manual and installs it in
38 can safely be repeated to rebuild the system from scratch.
40 At the end of the build,
42 prints suggested settings for the environment variables
46 After setting those, the script
48 will print a short summary of the installation output,
49 omitting the usual command chatter but preserving
50 compiler warnings and errors.
52 Plan 9 from User Space uses different threading implementations on Linux 2.6 and
53 later kernels than on 2.4 and earlier;
54 and on FreeBSD 5 and later kernels than on FreeBSD 4 and earlier.
55 Running binaries from one class on another will not work.
57 Some Linux 2.6 systems (e.g., Gentoo) do not use the new NPTL pthread library
58 even though the kernel supports them. On these systems, plan9port must
59 fall back on the threading code intended for Linux 2.4. To accomplish this,
61 checks whether the running system uses NPTL and sets
70 after this auto-detection and can be used to override the choices.
75 then the system is built without using X11.
