.Sh NAME
.Nm make.conf
.Nd system build information
.Sh DESCRIPTION
The file
.Nm
contains settings that control the compilation of the
.Fx
sources
and ported applications.
The file
.Nm
is generally created by the system administrator when the values need
to be changed from their defaults.
.Pp
The purpose of
.Nm
is not to run commands or perform compilation actions
directly.
Instead, it is included by the
various makefiles in
.Pa /usr/src ,
.Pa /usr/ports
and
.Pa /usr/doc
which conditionalize their
internal actions according to the settings found there.
.Pp
The
.Pa /etc/make.conf
file is included from the appropriate
.Pa Makefile
which specifies the default settings for all the available options.
Options need only be specified in
.Pa /etc/make.conf
when the system administrator wishes to override these defaults.
.Pp
The build procedures occur in four broad areas: the world, the kernel,
documentations and ports.
Variables set in
.Nm
may be applicable during builds in one, two, or all four of these
areas.
They may be specified for a particular build via the
.Fl D
option of
.Xr make 1 .
.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 CFLAGS
.Pq Vt str
Controls the compiler setting when compiling C code.
Optimization levels above
.Fl O
.Pq Fl O2 , No ...
are not supported.
.Va BDECFLAGS
