SRC.CONF(5)

NAME
src.conf - source build options

DESCRIPTION
The src.conf file contains settings that will apply to every build involving the FreeBSD source tree; see build(7).

The src.conf file uses the standard makefile syntax. However, src.conf should not specify any dependencies to make(1). Instead, src.conf is to set make(1) variables that control the aspects of how the system builds.

The default location of src.conf is /etc/src.conf, though an alternative location can be specified in the make(1) variable SRCCONF. Overriding the location of src.conf may be necessary if the system-wide settings are not suitable for a particular build. For instance, setting SRCCONF to /dev/null effectively resets all build controls to their defaults.

The only purpose of src.conf is to control the compilation of the FreeBSD source code, which is usually located in /usr/src. As a rule, the system administrator creates src.conf when the values of certain control variables need to be changed from their defaults.

In addition, control variables can be specified for a particular build via the -D option of make(1) or in its environment; see environ(7).

The values of variables are ignored regardless of their setting; even if they would be set to “FALSE” or “NO”. Just the existence of an option will cause it to be honoured by make(1).

The following list provides a name and short description for variables that can be used for source builds.
