Plan9/Build

Random notes on how to build 9front from source…

To rebuild the system I use the following commands:

% cd /
% . /sys/lib/rootstub

% cd /sys/src/
% mk nuke
% mk libs
% mk install
% mk clean

% cd /sys/man
% mk

% cd /sys/src/9/pc64
% mk install
% mk clean

% 9fs 9fat
% cp /amd64/9pc64 /n/9/
% unmount /n/9
% unmount /n/9fat
% rm /srv/dos

% fshalt -r

Note that when libraries are updated one ought to cd /sys/src/ && mk nuke them first before replacing them.

When new instructions are added to the assembler and linker, they need to be rebuilt before libc is rebuilt:

% for(i in (8a 8l 6a 6l)){ cd /sys/src/cmd/^$i && mk install }
