CONFIG(8) BSD System Manager's Manual CONFIG(8)
NAME
config - build system configuration files
SYNOPSIS
config [-p] [-g] SYSTEMNAME
DESCRIPTION
Config builds a set of system configuration files from the file
SYSTEMNAME which describes the system to configure. A second file tells
config what files are needed to generate a system and can be augmented by
a configuration specific set of files that give alternate files for a
specific machine. (See the FILES section below.)
Available options and operand:
-p If the -p option is supplied, config will configure a system
for profiling; see kgmon(8) and gprof(1).
-g If the -g option is supplied, two versions of the kernel
will be compiled, one of them with a complete symbol table
for symbolic debugging (see gdb(1)) and the other with a
normal symbol table (which is normally used for booting).
SYSTEMNAME This operand specifies the name of the system configuration
file containing device specifications, configuration options
and other system parameters for one system configuration.
Config should be run from the conf subdirectory of the system source for
a specific hardware type (such as /sys/i386/conf). Config places all out-
put files in the directory ../../compile/SYSTEMNAME. The output of
config consists of a number of files, including ioconf.c, a description
of what I/O devices are attached to the system; Makefile, used by make(1)
in building the system; header files, definitions of the number of vari-
ous devices that will be compiled into the system; swap configuration
files, definitions for the disk areas to be used for swapping, the root
file system, argument processing, and system dumps.
After running config, it is necessary to run ``make depend'' in the di-
rectory where the new makefile was created. Config prints a reminder of
this when it completes.
If any other error messages are produced by config, the problems in the
configuration file should be corrected and config should be run again.
Attempts to compile a system that had configuration errors are likely to
fail.
