NAME
install - notes about Plan 9 from User Space installation
SYNOPSIS
cd /usr/local/plan9; ./INSTALL [ -b | -c ] [ -r path ]
DESCRIPTION
To obtain the Plan 9 tree, use Git (see git(1)) or download
a tar file from https://9fans.github.io/plan9port.
The tree can be unpacked anywhere, but the usual place is
/usr/local/plan9. In the root of the tree, run ./INSTALL.
This script builds the Plan 9 build program mk(1) if neces-
sary, cleans all previously built object files and libraries
out of the tree, rebuilds and installs everything, and then
cleans up.
There are a few files in tree which have the root hard-coded
in them. After the build, INSTALL edits these files to
replace the string /usr/local/plan9 with the name of the
root of the current tree.
Finally, INSTALL builds an HTML version of the manual and
installs it in /usr/local/plan9/man.
The installation can be thought of as two steps: build all
the binaries, and then edit files as necessary to fix the
references to the installation root. If necessary, these
can be run separately. Given the -b flag, INSTALL performs
only the first step. Given the -c flag, INSTALL performs
only the second step. The first step can be done with the
tree in a temporary work directory, but the second step must
be done once the tree is in its final location. If you want
to build the project in one location and then install into
another location, use -r path to specify the final location
of Plan9 tree. These flags are only necessary when trying
to conform to the expectations of certain package management
systems.
At the end of the installation, INSTALL prints suggested
settings for the environment variables $PLAN9 and $PATH.
INSTALL writes various autodetected settings to
/usr/local/plan9/config. The file
/usr/local/plan9/LOCAL.config is appended to config after
this auto-detection and can be used to override the choices.
If LOCAL.config contains a line WSYSTYPE=nowsys then the
system is built without using X11. LOCAL.config may also
list settings for CC9 (the host C compiler) and CC9FLAGS
(any additional flags to pass to the compiler). Values more

complex than single words should be quoted with single
quotes.
On most Linux systems, the X11 header packages need to be
installed to build using X11. On Debian. the required pack-
ages are libfontconfig1-dev, libx11-dev, libxext-dev, and
libxt-dev. On Ubuntu, it suffices to install xorg-dev.
INSTALL can safely be repeated to rebuild the system from
scratch.
Once the system is built for the first time, it can be main-
tained and rebuilt using mk(1). To rebuild individual com-
mands or libraries, run mk install and mk clean in the
appropriate source directory (see src(1)).
