3 # If these # comments don't work, trim them. Don't worry about any other
4 # shell scripts, Configure will trim # comments from them for you.
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 package (which contains metaconfig) is available via SVN:
17 # svn co https://svn.sourceforge.net/svnroot/dist/trunk/dist
19 # Though this script was generated by metaconfig from metaunits, it is
20 # OK to send patches against Configure itself. It's up to the Configure
21 # pumpkin to backport the patch to the metaunits if it is accepted.
22 # For more information on patching Configure, see pod/perlhack.pod
24 # The metaunits are also available from the public git repository:
25 # http://perl5.git.perl.org/metaconfig.git/ or
26 # $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
28 # See Porting/pumpkin.pod for more information on metaconfig.

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

1700 Usage: $me [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
1701 [-U symbol] [-U symbol=] [-A command:symbol...]
1702 -d : use defaults for all answers.
1703 -e : go on without questioning past the production of config.sh.
1704 -f : specify an alternate default configuration file.
1705 -h : print this help message and exit (with an error status).
1706 -r : reuse C symbols value if possible (skips costly nm extraction).
1707 -s : silent mode, only echoes questions and essential information.
1708 -D : define symbol to have some value:
1709 -D symbol symbol gets the value 'define'
1710 -D symbol=value symbol gets the value 'value'
1711 common used examples (see INSTALL for more info):
1712 -Duse64bitint use 64bit integers
1713 -Duse64bitall use 64bit integers and pointers
1714 -Dusethreads use thread support
1715 -Dinc_version_list=none do not include older perl trees in @INC
1716 -DEBUGGING=none DEBUGGING options
1717 -Dcc=gcc choose your compiler
1718 -Dprefix=/opt/perl5 choose your destination
1719 -E : stop at the end of questions, after having produced config.sh.
1720 -K : do not use unless you know what you are doing.
1721 -O : let -D and -U override definitions from loaded configuration file.
1722 -S : perform variable substitutions on all .SH files (can mix with -f)
1723 -U : undefine symbol:
1724 -U symbol symbol gets the value 'undef'
1725 -U symbol= symbol gets completely empty
1727 -A : manipulate symbol after the platform specific hints have been applied:
1728 -A append:symbol=value append value to symbol
1729 -A symbol=value like append:, but with a separating space
1730 -A define:symbol=value define symbol to have value
1731 -A clear:symbol define symbol to be ''
1732 -A define:symbol define symbol to be 'define'
1733 -A eval:symbol=value define symbol to be eval of value
1734 -A prepend:symbol=value prepend value to symbol
1735 -A undef:symbol define symbol to be 'undef'
1736 -A undef:symbol= define symbol to be ''
1737 e.g.: -A prepend:libswanted='cl pthread '
1738 -A ccflags=-DSOME_MACRO
1739 -V : print version number and exit (with a zero status).

2234 This installation shell script will examine your system and ask you questions
2235 to determine how the perl5 package should be installed. If you get
2236 stuck on a question, you may use a ! shell escape to start a subshell or
2237 execute a command. Many of the questions will have default answers in square
2238 brackets; typing carriage return will give you the default.
2240 On some of the questions which ask for file or directory names you are allowed
2241 to use the ~name construct to specify the login directory belonging to "name",
2242 even if you don't have a shell which knows about that. Questions where this is
2243 allowed will be marked "(~name ok)".
2247 dflt='Type carriage return to continue'
2251 The prompter used in this script allows you to use shell variables and
2252 backticks in your answers. You may use $1, $2, etc... to refer to the words
2253 in the default answer, as if the default line was a set of arguments given to a
2254 script shell. This means you may also use $* to repeat the whole default line,
2255 so you do not have to re-type everything to add something to the default.
2257 Everytime there is a substitution, you will have to confirm. If there is an
2258 error (e.g. an unmatched backtick), the default answer will remain unchanged
2259 and you will be prompted again.
2261 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2262 the questions and use the computed defaults (or the previous answers if there
2263 was already a config.sh file). Type 'Configure -h' for a list of options.
2264 You may also start interactively and then answer '& -d' at any prompt to turn
2265 on the non-interactive behaviour for the remainder of the execution.
2271 Much effort has been expended to ensure that this shell script will run on any
2272 Unix system. If despite that it blows up on yours, your best bet is to edit
2273 Configure and run it again. If you can't run Configure for some reason,
2274 you'll have to generate a config.sh file by hand. Whatever problems you
2275 have, let me (perlbug@perl.org) know how I blew it.
2277 This installation script affects things in two ways:
2279 1) it may do direct variable substitutions on some of the files included
2281 2) it builds a config.h file for inclusion in C programs. You may edit
2282 any of these files as the need arises after running this script.
2284 If you make a mistake on a question, there is no easy way to back up to it
2285 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2286 files. Configure will offer to let you do this before it runs the SH files.
