The file make.conf contains system-wide settings that will apply to every build using make and the standard sys.mk file. The purpose of make.conf is to control the compilation of the FreeBSD sources, documentation, and ports.
The system build procedures occur in the following areas: the world, the kernel, documentation and ports. Variables set in make.conf 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 -D option of make or in environment.Print This Post
