| 17 | .SH DESCRIPTION | |
| 18 | .PP | |
| 19 | .I Config | |
| 20 | builds a set of system configuration files from a short file which describes | |
| 21 | the sort of system that is being configured. It also takes as input a file | |
| 22 | which tells | |
| 23 | .I config | |
| 24 | what files are needed to generate a system. | |
| aab530e6 KM |
25 | This can be augmented by a configuration specific set of files |
| 26 | that give alternate files for a specific machine. | |
| 27 | (see the FILES section below) | |
| 28 | If the | |
| 29 | .B \-p | |
| 30 | option is supplied, | |
| 31 | .I config | |
| 32 | will configure a system for profiling; c.f. | |
| 33 | .IR kgmon (8), | |
| 34 | .IR gprof (1). | |
| 8c7df50e KM |
35 | .PP |
| 36 | .I Config | |
| 37 | should be run from the | |
| 38 | .B conf | |
| aab530e6 | 39 | subdirectory of the system source (usually /sys/conf). |
| 8c7df50e KM |
40 | .I Config |
| 41 | assumes that there is already a directory | |
| 42 | .I "../config_file" | |
| 43 | created and it places all its output files in there. | |
| 44 | The output of | |
| 45 | .I config | |
| 46 | consists of a number files: | |
| 47 | .B ioconf.c | |
| aab530e6 KM |
48 | contains a description |
| 49 | of what i/o devices are attached to the system,; | |
| 8c7df50e | 50 | .B ubglue.s |
| aab530e6 KM |
51 | contains a set of interrupt service routines for devices |
| 52 | attached to the UNIBUS; | |
| 8c7df50e | 53 | .B makefile |
| aab530e6 KM |
54 | is a file used by |
| 55 | .IR make (1) | |
| 56 | in building the system; a set of header files which contain | |
| 57 | the number of various devices that will be compiled into the system; | |
| 58 | and a set of swap configuration files which contain definitions for | |
| 59 | the disk areas to be used for swapping, the root file system, | |
| 60 | argument processing, and system dumps. | |
| 8c7df50e KM |
61 | .PP |
| 62 | After running | |
| aab530e6 | 63 | .IR config , |
| 8c7df50e KM |
64 | it is necessary to run "make depend" in the directory where the new makefile |
| 65 | was created. | |
| 66 | .I Config | |
| 67 | reminds you of this when it completes. | |
| 68 | .PP | |
| 69 | If you get any other error messages from | |
| 70 | .I config, | |
| 71 | you should fix the problems in your configuration file and try again. | |
| aab530e6 KM |
72 | If you try to compile a system that had configuration errors, you |
| 73 | will likely meet with failure. | |
