       genksyms  [-wq]  [-dD] [-V] [-k version] [-p string] [out­
       put directory]


       Genksyms reads (on standard input) the output from "gcc -E
       source.c" and generates a file containing version informa­

       Depending on the output format indicated by the -k option,
       the  output  will  either be written to a .ver file in the
       named output directory, or to the standard output.

       Genksyms normally looks for explicit symbol table  defini­
       tions  in  the  source file.  All definitions and declara­
       tions of typedef, struct, union and enum will be saved for
       later  expansion.  Every global symbol will also be saved,
       together with pointers that will enable a  full  expansion
       later on.

       When  a  symbol  table  is found in the source, the symbol
       will  be  expanded  to  its  full  definition,  where  all
       structs,  unions, enums and typedefs will be expanded down
       to their basic part, recursively.  This final string  will
       then be used as input to a CRC algorithm that will give an
       integer that will change as soon as any  of  the  included
       definitions changes, for this symbol.

       The version information in the kernel normally looks like:
       symbol_R12345678, where 12345678 is the hexadecimal repre­
       sentation of the CRC.


       -d, --debug
              Output debugging information; repeating this option
              increases the verbosity.  Debug level  1  generates
              moderate information about the actions being taken;
              debug level 2 enables  parser  recognition  output;
              debug level 3 enables lexical analysis output.

       -D, --dump
              Dump  expanded  symbol  definitions to stderr.  For
              debugging use only.

       -h, --help
              Display a summary of options and immediately  exit.

       -k version, --kernel version
              Select  the version of the kernel for which to gen­
              erate output.  Omitting this option assumes a  ver­
              sion below 2.1.0.  Versions below 2.1.18 use check­
              sum version 1, and  produce  their  output  in  the

       -V, --version
              Display the version of genksyms.

       -w, --warnings
              Enable warnings  due  to  unrecognized  syntax  and
              declared  but undefined structures.  These warnings
              are normally suppressed.


       insmod(8), modprobe(8)


       The -h option is broken; --help is fine.
       genksyms [-V | --version] should display version  informa­
       tion  and  then  exit immediately.  Instead, it prints the
       version information and behaves  as  if  no  options  were

       Although  the  fix for this bug is trivial, it changes the
       behaviour of modutils.  Given the large number of  distri­
       butions  and scripts that run modutils and expect the cur­
       rent behaviour, any change of behaviour is unacceptable in
       2.4.   Don't  bother sending patches for this bug, it will
       not be fixed in 2.4, it should be fixed in 2.5.


       This versioning concept is a result from discussions,  not
       at least on the KERNEL-channel, with a lot of people.

       The  genksyms  utility was created in 1994 by Bjorn Ekwall
       <bj0rn@blox.se> being mostly inspired by  Jacques  Gelinas
       <jack@solucorp.ca>       and      Jeremy      Fitzhardinge

       It was rewritten in 1996 by Richard  Henderson  to  use  a
       proper lexer and parser.
