7 # I would suggest you have a look at the prototypical config_h.SH file
8 # and edit it to reflect your system. Some packages may include samples
9 # of config.h for certain machines, so you might look for one of those.)

15 # working with this copy of Configure, you may wish to get metaconfig.
16 # The dist-3.0 package (which contains metaconfig) was posted in
17 # comp.sources.misc so you may fetch it yourself from your nearest
18 # archive site. Check with Archie if you don't know where that can be.)

28 SCO csh still thinks true is false. Write to SCO today and tell them that next
29 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
32 we'd have to do is go in and swap the && and || tokens, wherever they are.)

1152 This installation shell script will examine your system and ask you questions
1153 to determine how the perl5 package should be installed. If you get
1154 stuck on a question, you may use a ! shell escape to start a subshell or
1155 execute a command. Many of the questions will have default answers in square
1156 brackets; typing carriage return will give you the default.
1158 On some of the questions which ask for file or directory names you are allowed
1159 to use the ~name construct to specify the login directory belonging to "name",
1160 even if you don't have a shell which knows about that. Questions where this is
1161 allowed will be marked "(~name ok)".
1165 dflt='Type carriage return to continue'
1169 The prompter used in this script allows you to use shell variables and
1170 backticks in your answers. You may use $1, $2, etc... to refer to the words
1171 in the default answer, as if the default line was a set of arguments given to a
1172 script shell. This means you may also use $* to repeat the whole default line,
1173 so you do not have to re-type everything to add something to the default.
1175 Everytime there is a substitution, you will have to confirm. If there is an
1176 error (e.g. an unmatched backtick), the default answer will remain unchanged
1177 and you will be prompted again.
1179 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1180 the questions and use the computed defaults (or the previous answers if there
1181 was already a config.sh file). Type 'Configure -h' for a list of options.
1182 You may also start interactively and then answer '& -d' at any prompt to turn
1183 on the non-interactive behaviour for the remaining of the execution.
1189 Much effort has been expended to ensure that this shell script will run on any
1190 Unix system. If despite that it blows up on yours, your best bet is to edit
1191 Configure and run it again. If you can't run Configure for some reason,
1192 you'll have to generate a config.sh file by hand. Whatever problems you
1193 have, let me (lwall@netlabs.com) know how I blew it.
1195 This installation script affects things in two ways:
1197 1) it may do direct variable substitutions on some of the files included
1199 2) it builds a config.h file for inclusion in C programs. You may edit
1200 any of these files as the need arises after running this script.
1202 If you make a mistake on a question, there is no easy way to back up to it
1203 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1204 files. Configure will offer to let you do this before it runs the SH files.

3724 Some versions of Unix support shared libraries, which make executables smaller
3725 but make load time slightly longer.
3727 On some systems, mostly newer Unix System V's, the shared library is included
3728 by putting the option "-lc_s" as the last thing on the cc command line when
3729 linking. Other systems use shared libraries by default. There may be other
3730 libraries needed to compile $package on your machine as well. If your system
3731 needs the "-lc_s" option, include it here. Include any other special libraries
3732 here as well. Say "none" for none.

3762 I can use 'nm' to extract the symbols from your C libraries. This is a time
3763 consuming task which may generate huge output on the disk (up to 3 megabytes)
3764 but that should make the symbols extraction faster. The alternative is to skip
3765 the 'nm' extraction part and to compile a small test program instead to
3766 determine whether each symbol is present. If you have a fast C compiler and/or
3767 if your 'nm' output cannot be parsed, this may be the best solution.
