.Dt MAKE.CONF 5
|
|
.Os
|
|
.Sh NAME
|
|
.Nm make.conf
|
|
.Nd system build information
|
|
.Sh DESCRIPTION
|
|
The file
|
|
.Nm
|
|
contains system-wide settings that will apply to every build using
|
|
.Xr make 1
|
|
and the standard
|
|
.Pa sys.mk
|
|
file.
|
|
This is achieved as follows:
|
|
.Xr make 1
|
|
processes the system makefile
|
|
.Pa sys.mk
|
|
before any other file by default, and
|
|
.Pa sys.mk
|
|
includes
|
|
.Nm .
|
|
.Pp
|
|
The file
|
|
.Nm
|
|
uses the standard makefile syntax.
|
|
However,
|
|
.Nm
|
|
should not specify any dependencies to
|
|
.Xr make 1 .
|
|
Instead,
|
|
.Nm
|
|
is to set
|
|
.Xr make 1
|
|
variables that control the actions of other makefiles.
|
|
.Pp
|
|
The default location of
|
|
.Nm
|
|
is
|
|
.Pa /etc/make.conf ,
|
|
though an alternative location can be specified in the
|
|
.Xr make 1
|
|
variable
|
|
.Va __MAKE_CONF .
|
|
You may need to override the location of
|
|
.Nm
|
|
if the system-wide settings are not suitable for a particular build.
|
|
For instance, setting
|
|
.Va __MAKE_CONF
|
|
to
|
|
.Pa /dev/null
|
|
effectively resets all build controls to their defaults.
|
|
.Pp
|
|
The primary purpose of
|
|
.Nm
|
|
is to control the compilation of the
|
|
.Fx
|
|
sources, documentation, and ported applications,
|
|
which are usually found in
|
|
.Pa /usr/src ,
|
|
.Pa /usr/doc ,
|
|
and
|
|
.Pa /usr/ports .
|
|
As a rule, the system administrator creates
|
|
.Nm
|
|
when the values of certain control variables need to be changed
|
|
from their defaults.
|
|
.Pp
|
|
The system build procedures occur in four broad areas:
|
|
the world, the kernel, documentation and ports.
|
|
Variables set in
|
|
.Nm
|
|
may be applicable in one, two, or all four of these areas.
|
|
In addition, control variables can be specified
|
|
for a particular build via the
|
|
.Fl D
|
|
option of
|
|
.Xr make 1
|
|
or in
|
|
.Xr environ 7 .
|
|
In the case of world and kernel builds it is possible to put these variables
|
|
into
|
|
.Xr src.conf 5
|
|
instead of
|
|
.Nm .
|
|
This way the environment for documentation and ports builds is not polluted
|
|
by unrelated variables.
|
|
.Pp
|
|
The following lists provide a name and short description for each
|
|
variable you can use during the indicated builds.
|
|
The values of
|
|
variables flagged as
|
|
.Vt bool
|
|
are ignored; the variable being
|
|
set at all (even to
|
|
.Dq Li FALSE
|
|
or
|
|
.Dq Li NO )
|
|
causes it to
|
|
be treated as if it were set.
|
|
.Pp
|
|
The following list provides a name and short description for variables
|
|
that are used for all builds, or are used by the
|
|
.Pa makefiles
|
|
for things other than builds.
|
|
.Bl -tag -width Ar
|
|
.It Va ALWAYS_CHECK_MAKE
|
|
.Pq Vt bool
|
|
Instructs the top-level makefile in the source tree (normally
|
|
.Pa /usr/src )
|
|
to always check if
|
|
.Xr make 1
|
|
is up-to-date.
|
|
Normally this is only done for the world and buildworld targets to handle
|
|
upgrades from older versions of
|
|
.Fx .
|
|
.It Va CFLAGS
|
|
.Pq Vt str
|
|
Controls the compiler setting when compiling C code.
|
|
Optimization levels other than
|
|
.Fl O
|
|
and
|
|
.Fl O2
|
|
are not supported.
|
|
.It Va CPUTYPE
|
|
.Pq Vt str
|
|
Controls which processor should be targeted for generated
|
|
code.
|
|
This controls processor-specific optimizations in
|
|
certain code (currently only OpenSSL) as well as modifying
|
|
the value of
|
|
.Va CFLAGS
|
|
and
|
|
.Va COPTFLAGS
|
|
to contain the appropriate optimization directive to
|
|
.Xr cc 1 .
|
|
The automatic setting of
|
|
.Va CFLAGS
|
|
may be overridden using the
|
|
.Va NO_CPU_CFLAGS
|
|
variable.
|
|
Refer to
|
|
.Pa /usr/share/examples/etc/make.conf
|
|
for a list of recognized
|
|
.Va CPUTYPE
|
|
options.
|
|
.It Va CXXFLAGS
|
|
.Pq Vt str
|
|
Controls the compiler settings when compiling C++ code.
|
|
.Va CXXFLAGS
|
|
is initially set to the value of
|
|
.Va CFLAGS .
|
|
If you want to
|
|
add to the
|
|
.Va CXXFLAGS
|
|
value, use
|
|
.Dq Li +=
|
|
instead of
|
|
.Dq Li = .
|
|
.It Va DTC
|
|
.Pq Vt str
|
|
Select the compiler for DTS (Device Tree Syntax) file.
|
|
.Va DTC
|
|
is initially set to the value of dtc
|
|
.It Va INSTALL
|
|
.Pq Vt str
|
|
the default install command.
|
|
To install only files for which the target differs or does not exist, use
|
|
.Bd -literal -offset indent
|
|
INSTALL+= -C
|
|
.Ed
|
|
Note that some makefiles (including those in
|
|
.Pa /usr/share/mk )
|
|
may hardcode options for the supplied install command.
|
|
.It Va LOCAL_DIRS
|
|
.Pq Vt str
|
|
List any directories that should be entered when doing
|
|
make's in
|
|
.Pa /usr/src
|
|
in this variable.
|
|
.It Va MAKE_SHELL
|
|
.Pq Vt str
|
|
Controls the shell used internally by
|
|
.Xr make 1
|
|
to process the command scripts in makefiles.
|
|
.Xr sh 1 ,
|
|
.Xr ksh 1 ,
|
|
and
|
|
.Xr csh 1
|
|
all currently supported.
|
|
.Pp
|
|
.Dl "MAKE_SHELL?=sh"
|
|
.It Va MTREE_FOLLOWS_SYMLINKS
|
|
.Pq Vt str
|
|
Set this to
|
|
.Dq Fl L
|
|
to cause
|
|
.Xr mtree 8
|
|
to follow symlinks.
|
|
.It Va NO_CPU_CFLAGS
|
|
.Pq Vt str
|
|
Setting this variable will prevent CPU specific compiler flags
|
|
from being automatically added to
|
|
.Va CFLAGS
|
|
during compile time.
|
|
.El
|
|
.Ss "BUILDING THE KERNEL"
|
|
The following list provides a name and short description for variables
|
|
that are only used doing a kernel build:
|
|
.Bl -tag -width Ar
|
|
.It Va BOOTWAIT
|
|
.Pq Vt int
|
|
Controls the amount of time the kernel waits for a console keypress
|
|
before booting the default kernel.
|
|
The value is approximately milliseconds.
|
|
Keypresses are accepted by the BIOS before booting from disk,
|
|
making it possible to give custom boot parameters even when this is
|
|
set to 0.
|
|
.It Va COPTFLAGS
|
|
.Pq Vt str
|
|
Controls the compiler settings when building the
|
|

|
are not guaranteed to work.
|
|
.It Va KERNCONF
|
|
.Pq Vt str
|
|
Controls which kernel configurations will be
|
|
built by
|
|
.Dq Li "${MAKE} buildkernel"
|
|
and installed by
|
|
.Dq Li "${MAKE} installkernel" .
|
|
For example,
|
|
.Bd -literal -offset indent
|
|
KERNCONF=MINE DEBUG GENERIC OTHERMACHINE
|
|
.Ed
|
|
.Pp
|
|
will build the kernels specified by the config files
|
|
.Pa MINE , DEBUG , GENERIC ,
|
|
and
|
|
.Pa OTHERMACHINE ,
|
|
and install the kernel specified by the config file
|
|
.Pa MINE .
|
|
It defaults to
|
|
.Pa GENERIC .
|
|
.It Va MODULES_OVERRIDE
|
|
.Pq Vt str
|
|
Set to a list of modules to build instead of all of them.

|
Set this to skip running
|
|
.Dq Li "${MAKE} clean"
|
|
during
|
|
.Dq Li "${MAKE} buildkernel" .
|
|
.It Va NO_KERNELCONFIG
|
|
.Pq Vt bool
|
|
Set this to skip running
|
|
.Xr config 8
|
|
during

.It Va NO_MODULES
|
|
.Pq Vt bool
|
|
Set to not build modules with the kernel.
|
|
.It Va PORTS_MODULES
|
|
Set this to the list of ports you wish to rebuild every time the kernel
|
|
is built.
|
|
.It Va WITHOUT_MODULES
|
|
.Pq Vt str
|
|
Set to a list of modules to exclude from the build.
|
|
This provides a
|
|
somewhat easier way to exclude modules you are certain you will never
|
|
need than specifying
|
|
.Va MODULES_OVERRIDE .
|
|
This is applied
|
|
.Em after
|
|
.Va MODULES_OVERRIDE .
|
|
.El
|
|
.Ss "BUILDING THE WORLD"
|
|
The following list provides a name and short description for variables
|

that are used during the world build:
|
|
.Bl -tag -width Ar
|
|
.It Va BOOT_COMCONSOLE_PORT
|
|
.Pq Vt str
|
|
The port address to use for the console if the boot blocks have
|
|
been configured to use a serial console instead of the keyboard/video card.
|
|
.It Va BOOT_COMCONSOLE_SPEED
|
|
.Pq Vt int
|
|
The baud rate to use for the console if the boot blocks have
|
|
been configured to use a serial console instead of the keyboard/video card.
|
|
.It Va BOOT_PXELDR_ALWAYS_SERIAL
|
|
.Pq Vt bool
|
|
Compile in the code into
|
|
.Xr pxeboot 8
|
|
that forces the use of a serial console.
|
|
This is analogous to the

|
option in
|
|
.Xr boot 8
|
|
blocks.
|
|
.It Va BOOT_PXELDR_PROBE_KEYBOARD
|
|
.Pq Vt bool
|
|
Compile in the code into
|
|
.Xr pxeboot 8
|
|
that probes the keyboard.
|
|
If no keyboard is found, boot with the dual console configuration.
|
|
This is analogous to the
|
|
.Fl D
|
|
option in
|
|
.Xr boot 8
|
|
blocks.
|
|
.It Va ENABLE_SUID_K5SU
|
|
.Pq Vt bool
|

|
.Xr pxeboot 8
|
|
loader retrieves the kernel via NFS.
|
|
Defining this and recompiling
|
|
.Pa /usr/src/stand
|
|
will cause it to retrieve the kernel via TFTP.
|
|
This allows
|
|
.Xr pxeboot 8
|
|
to load a custom BOOTP diskless kernel yet
|
|
still mount the server's
|
|
.Pa /
|
|
rather than load the server's kernel.
|
|
.It Va LOADER_FIREWIRE_SUPPORT
|
|
.Pq Vt bool
|
|
Defining this and recompiling
|
|
.Pa /usr/src/stand/i386
|
|
will add
|
|
.Xr dcons 4
|
|
console driver to
|
|
.Xr loader 8
|
|
and allow access over FireWire(IEEE1394) using
|

installs all available architectures.
|
|
It is also the default value.
|
|
.It Va MODULES_WITH_WORLD
|
|
.Pq Vt bool
|
|
Set to build modules with the system instead of the kernel.
|
|
.It Va NO_CLEAN

.Pq Vt bool
|
|
Set this to disable cleaning during
|
|
.Dq Li "make buildworld" .
|
|
This should not be set unless you know what you are doing.
|
|
.It Va NO_CLEANDIR
|
|
.Pq Vt bool
|
|
Set this to run
|
|
.Dq Li "${MAKE} clean"
|
|
instead of
|
|
.Dq Li "${MAKE} cleandir" .
|
|
.It Va WITH_MANCOMPRESS
|
|
.Pq Vt defined
|
|
Set to install manual pages compressed.

.Pq Vt bool
|
|
Set to build
|
|
.Pa /bin
|
|
and

|
.Pa /sbin
|
|
statically linked, this can be bad.
|
|
If set, every utility that uses
|
|
.Pa bsd.prog.mk
|
|
will be linked statically.
|
|
.It Va PKG_REPO_SIGNING_KEY
|
|
.Pq Vt str
|
|
Path to rsa private key passed to
|
|
.Xr pkg-repo 8
|
|
to sign packages created when building the
|
|
.Ar packages
|
|
target, i.e.: pkgbase.
|
|
The variable is named the same in
|
|
.Xr poudriere 8
|
|
so it will automatically be picked up when building pkgbase with poudriere.
|
|
.It Va PPP_NO_NAT
|
|
.Pq Vt bool
