The Makefile in this directory supports a number of targets for
building components (or all) of the DragonFly source tree, the most
commonly used being ``buildworld'' and ``installworld'', which rebuild
and install everything in the DragonFly system from the source tree
except the kernel, the kernel-modules and the contents of /etc. The
``buildkernel'' and ``installkernel'' targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat involved process. Documentation
for it can be found at:
Also see the build(7) and config(8) man pages.
Note: If you want to build and install the kernel with the
``buildkernel'' and ``installkernel'' targets, you might need to build
world before. More information is available in the DragonFly handbook.
The kernel configuration files reside in the sys/config sub-directory.
The X86_64_GENERIC is the default x86_64 kernel configuration used in
release builds. The VKERNEL64 is the default 64 bit vkernel(7) kernel
configuration file. The file LINT64 contains entries for all possible
devices, not just those commonly used, and is meant more as a general
reference than an actual kernel configuration file (a kernel built
from it wouldn't even run). Also see the config(8) man page.
