.Sh NAME
|
|
.Nm build
|
|
.Nd information on how to build the system
|
|
.Sh DESCRIPTION
|
|
The sources for the
|
|
.Fx
|
|
system and its applications are contained in three different directories,
|
|
normally
|
|
.Pa /usr/src ,
|
|
.Pa /usr/doc ,
|
|
and
|
|
.Pa /usr/ports .
|
|
Directory
|
|
.Pa /usr/src
|
|
contains the
|
|
.Dq "base system"
|
|
sources, which is loosely defined as the things required to rebuild
|
|
the system to a useful state.
|
|
Directory
|
|
.Pa /usr/doc
|
|
contains the source for the system documentation, excluding the manual
|
|
pages.
|
|
Directory
|
|
.Pa /usr/ports
|
|
contains a tree that provides a consistent interface for building and
|
|
installing third party applications.
|
|
For more information about the ports build process, see
|
|
.Xr ports 7 .
|
|
.Pp
|
|
The
|
|
.Xr make 1
|
|
command is used in each of these directories to build and install the
|
|
things in that directory.
|
|
Issuing the
|
|
.Xr make 1
|
|
command in any directory or
|
|
subdirectory of those directories has the same effect as issuing the
|
|
same command in all subdirectories of that directory.
|
|
With no target specified, the things in that directory are just built.
|
|
.Pp
|
|
A source tree is allowed to be read-only.
|
|
As described in
|
|
.Xr make 1 ,
|
|
objects are usually built in a separate object directory hierarchy
|
|
specified by the environment variable
|
|
.Va MAKEOBJDIRPREFIX ,
|
|
or under
|
|
.Pa /usr/obj
|
|
if variable
|
|
.Va MAKEOBJDIRPREFIX
|
|
is not set.
|
|
For a given source directory, its canonical object directory
|
|
would be
|
|
.Pa ${MAKEOBJDIRPREFIX}${.CURDIR}
|
|
if
|
|
.Xr make 1
|
|
variable
|
|
.Va MAKEOBJDIRPREFIX
|
|
is set, or
|
|
.Pa /usr/obj${.CURDIR}
|
|
if this variable is not set.
|
|
Cross-builds set the object directory as described in the
|
|
documentation for the
|
|
.Cm buildworld
|
|
target below.
|
|
.Pp
|
|
The build may be controlled by defining
|
|
.Xr make 1
|
|
variables described in the
|
|
.Sx ENVIRONMENT
|
|
section below, and by the variables documented in
|
|
.Xr make.conf 5 .
|
|
.Pp
|
|
The following list provides the names and actions for the targets
|
|
supported by the build system:
|
|
.Bl -tag -width ".Cm cleandepend"
|
|
.It Cm clean
|
|
Remove any files created during the build process.
|
|
.It Cm cleandepend
|
|
Remove the file
|
|
.Pa ${.OBJDIR}/${DEPENDFILE}
|
|
generated by a prior
|
|
.Dq Li "make depend"
|
|
step.
|
|
.It Cm cleandir
|
|
Remove the canonical object directory if it exists, or perform
|
|
actions equivalent to
|
|
.Dq Li "make clean cleandepend"
|
|
if it does not.
|
|
This target will also remove an
|
|
.Pa obj
|
|
link in
|
|
.Pa ${.CURDIR}
|
|
if that exists.
|
|
.Pp
|
|
It is advisable to run
|
|
.Dq Li "make cleandir"
|
|
twice: the first invocation will remove the canonical object directory
|
|
and the second one will clean up
|
|
.Pa ${.CURDIR} .
|
|
.It Cm depend
|
|
Generate a list of build dependencies in file
|
|
.Pa ${.OBJDIR}/${DEPENDFILE} .

|
Install the results of the build to the appropriate location in the
|
|
installation directory hierarchy specified in variable
|
|
.Va DESTDIR .
|
|
.It Cm obj
|
|
Create the canonical object directory associated with the current
|
|
directory.
|
|
.It Cm objlink
|
|
Create a symbolic link to the canonical object directory in

|
.Pa ${.CURDIR} .
|
|
.It Cm tags
|
|
Generate a tags file using the program specified in the
|

|
|
.Xr ctags 1
|
|
and
|
|
.Nm "GNU Global" .
|
|
.El
|
|
.Pp
|
|
The other supported targets under directory

|
.Pa /usr/src
|
|
are:
|
|
.Bl -tag -width ".Cm distributeworld"
|
|
.It Cm buildenv
|
|
Spawn an interactive shell with environment variables set up for
|
|
cross-building the system.
|
|
The target architecture needs to be specified with
|
|
.Xr make 1
|
|
variables
|
|
.Va TARGET_ARCH
|
|
and
|
|
.Va TARGET .
|
|
.Pp
|
|
This target is only useful after a complete cross-toolchain including
|

|
.Pa ${MAKEOBJDIRPREFIX}${.CURDIR}
|
|
for native builds, and
|
|
.Pa ${MAKEOBJDIRPREFIX}/${TARGET}${.CURDIR}
|
|
for cross builds and native builds with variable

Execute a
|
|
.Cm buildworld
|
|
and
|
|
.Cm buildkernel
|

if it contained the currently running kernel.
|
|
The target directory under
|
|
.Pa ${DESTDIR}
|
|
may be modified using the
|

|
|
.Xr make 1
|
|
variable
|
|
.Va INSTKERNNAME .
|
|
.El
|
|
.Pp
|
|
Convenience targets for cleaning up the install destination directory
|
|
denoted by variable

|
Delete obsolete base system files and directories interactively.
|
|
When
|
|
.Li -DBATCH_DELETE_OLD_FILES
|
|
is specified at the command line, the delete operation will be
|
|
non-interactive.
|
|
The variables
|
|
.Va DESTDIR ,
|
|
.Va TARGET_ARCH
|
|
and
|
|
.Va TARGET
|
|
should be set as with
|
|
.Dq Li "make installworld" .
|
|
.It Cm delete-old-libs
|
|
Delete obsolete base system libraries interactively.
|
|
This target should only be used if no 3rd party software uses these
|
|
libraries.
|
|
When
|
|
.Li -DBATCH_DELETE_OLD_FILES
|
|
is specified at the command line, the delete operation will be
|
|
non-interactive.
|
|
The variables
|
|
.Va DESTDIR ,
|
|
.Va TARGET_ARCH
|
|
and
|
|
.Va TARGET
|
|
should be set as with
|
|
.Dq Li "make installworld" .
|
|
.El
|
|
.Sh ENVIRONMENT
|
|
Variables that influence all builds include:
|
|
.Bl -tag -width ".Va MAKEOBJDIRPREFIX"
|
|
.It Va DESTDIR
|
|
The directory hierarchy prefix where built objects will be installed.
|
|
If not set,
|
|
.Va DESTDIR
|
|
defaults to the empty string.
|
|
.It Va MAKEOBJDIRPREFIX
|
|
Defines the prefix for directory names in the tree of built objects.
|
|
Defaults to
|
|
.Pa /usr/obj
|
|
if not defined.
|
|
This variable should only be set in the environment and not via
|
|
.Pa /etc/make.conf
|
|
or the command line.
|
|
.It Va NO_WERROR
|
|
If defined, compiler warnings will not cause the build to halt,
|
|
even if the makefile says otherwise.
|
|
.El
|
|
.Pp
|
|
Additionally, builds in
|
|
.Pa /usr/src
|
|
are influenced by the following
|
|
.Xr make 1
|
|
variables:
|
|
.Bl -tag -width ".Va SUBDIR_OVERRIDE"
|
|
.It Va LOCAL_DIRS
|
|
If set, this variable supplies a list of additional directories to
|
|
build, relative to the root of the source tree.
|
|
.It Va SUBDIR_OVERRIDE
|
|
Override the default list of sub-directories and only build the
|
|
sub-directory named in this variable.
|
|
This variable is useful when debugging failed builds.
|
|
.Bd -literal -offset indent
|
|
make some-target SUBDIR_OVERRIDE=foo/bar
|
|
.Ed
|
|
.It Va TARGET
|
|
The target hardware platform.
|
|
This is analogous to the
|
|
.Dq Nm uname Fl m
|
|
output.
|
|
This is necessary to cross-build some target architectures.
|
|
For example, cross-building for PC98 machines requires
|
|
.Va TARGET_ARCH Ns = Ns Li i386
|
|
and
|
|
.Va TARGET Ns = Ns Li pc98 .
|
|
If not set,
|
|
.Va TARGET
|
|
defaults to the current hardware platform.
|
|
.It Va TARGET_ARCH
|
|
The target machine processor architecture.
|
|
This is analogous to the
|
|
.Dq Nm uname Fl p
|
|
output.
|
|
Set this to cross-build for a different architecture.
|
|
If not set,
|
|
.Va TARGET_ARCH
|
|
defaults to the current machine architecture.
|
|
.El
|
|
.Pp
|
|
Builds under directory
|
|
.Pa /usr/doc
|
|
are influenced by the following
|
|
.Xr make 1
|
|
variables:
|
|
.Bl -tag -width ".Va DOC_LANG"
|
|
.It Va DOC_LANG
|
|
If set, restricts the documentation build to the language subdirectories
|
|
specified as its content.
|
|
The default action is to build documentation for all languages.
