6 # (If you are trying to port this package to a machine without sh,
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.)
11 # Yes, you may rip this off to use in other distribution packages. This
12 # script belongs to the public domain and cannot be copyrighted.
14 # (Note: this Configure script was generated automatically. Rather than
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 and is available on CPAN under authors/id/RAM so
18 # you may fetch it yourself from your nearest archive site.)
21 # Though this script was generated by metaconfig, it is OK to send
22 # patches against it. It's up to the Configure pumpkin to backport
23 # the patch to the metaunits if it is accepted.
24 # See Porting/pumpkin.pod for more information on metaconfig.

35 SCO csh still thinks true is false. Write to SCO today and tell them that next
36 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
38 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
39 we'd have to do is go in and swap the && and || tokens, wherever they are.)
41 [End of diatribe. We now return you to your regularly scheduled programming...]

1664 Usage: $me [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
1665 [-U symbol] [-U symbol=] [-A command:symbol...]
1666 -d : use defaults for all answers.
1667 -e : go on without questioning past the production of config.sh.
1668 -f : specify an alternate default configuration file.
1669 -h : print this help message and exit (with an error status).
1670 -r : reuse C symbols value if possible (skips costly nm extraction).
1671 -s : silent mode, only echoes questions and essential information.
1672 -D : define symbol to have some value:
1673 -D symbol symbol gets the value 'define'
1674 -D symbol=value symbol gets the value 'value'
1675 common used examples (see INSTALL for more info):
1676 -Duse64bitint use 64bit integers
1677 -Duse64bitall use 64bit integers and pointers
1678 -Dusethreads use thread support
1679 -Dinc_version_list=none do not include older perl trees in @INC
1680 -DEBUGGING=none DEBUGGING options
1681 -Dcc=gcc choose your compiler
1682 -Dprefix=/opt/perl5 choose your destination
1683 -E : stop at the end of questions, after having produced config.sh.
1684 -K : do not use unless you know what you are doing.
1685 -O : let -D and -U override definitions from loaded configuration file.
1686 -S : perform variable substitutions on all .SH files (can mix with -f)
1687 -U : undefine symbol:
1688 -U symbol symbol gets the value 'undef'
1689 -U symbol= symbol gets completely empty
1691 -A : manipulate symbol after the platform specific hints have been applied:
1692 -A append:symbol=value append value to symbol
1693 -A symbol=value like append:, but with a separating space
1694 -A define:symbol=value define symbol to have value
1695 -A clear:symbol define symbol to be ''
1696 -A define:symbol define symbol to be 'define'
1697 -A eval:symbol=value define symbol to be eval of value
1698 -A prepend:symbol=value prepend value to symbol
1699 -A undef:symbol define symbol to be 'undef'
1700 -A undef:symbol= define symbol to be ''
1701 e.g.: -A prepend:libswanted='cl pthread '
1702 -A ccflags=-DSOME_MACRO
1703 -V : print version number and exit (with a zero status).

2193 This installation shell script will examine your system and ask you questions
2194 to determine how the perl5 package should be installed. If you get
2195 stuck on a question, you may use a ! shell escape to start a subshell or
2196 execute a command. Many of the questions will have default answers in square
2197 brackets; typing carriage return will give you the default.
2199 On some of the questions which ask for file or directory names you are allowed
2200 to use the ~name construct to specify the login directory belonging to "name",
2201 even if you don't have a shell which knows about that. Questions where this is
2202 allowed will be marked "(~name ok)".
2206 dflt='Type carriage return to continue'
2210 The prompter used in this script allows you to use shell variables and
2211 backticks in your answers. You may use $1, $2, etc... to refer to the words
2212 in the default answer, as if the default line was a set of arguments given to a
2213 script shell. This means you may also use $* to repeat the whole default line,
2214 so you do not have to re-type everything to add something to the default.
2216 Everytime there is a substitution, you will have to confirm. If there is an
2217 error (e.g. an unmatched backtick), the default answer will remain unchanged
2218 and you will be prompted again.
2220 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2221 the questions and use the computed defaults (or the previous answers if there
2222 was already a config.sh file). Type 'Configure -h' for a list of options.
2223 You may also start interactively and then answer '& -d' at any prompt to turn
2224 on the non-interactive behaviour for the remainder of the execution.
2230 Much effort has been expended to ensure that this shell script will run on any
2231 Unix system. If despite that it blows up on yours, your best bet is to edit
2232 Configure and run it again. If you can't run Configure for some reason,
2233 you'll have to generate a config.sh file by hand. Whatever problems you
2234 have, let me (perlbug@perl.org) know how I blew it.
2236 This installation script affects things in two ways:
2238 1) it may do direct variable substitutions on some of the files included
2240 2) it builds a config.h file for inclusion in C programs. You may edit
2241 any of these files as the need arises after running this script.
2243 If you make a mistake on a question, there is no easy way to back up to it
2244 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2245 files. Configure will offer to let you do this before it runs the SH files.

7276 I can use $nm to extract the symbols from your C libraries. This
7277 is a time consuming task which may generate huge output on the disk (up
7278 to 3 megabytes) but that should make the symbols extraction faster. The
7279 alternative is to skip the 'nm' extraction part and to compile a small
7280 test program instead to determine whether each symbol is present. If
7281 you have a fast C compiler and/or if your 'nm' output cannot be parsed,
7282 this may be the best solution.
7284 You probably shouldn't let me use 'nm' if you are using the GNU C Library.
