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...]

1695 Usage: $me [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
1696 [-U symbol] [-U symbol=] [-A command:symbol...]
1697 -d : use defaults for all answers.
1698 -e : go on without questioning past the production of config.sh.
1699 -f : specify an alternate default configuration file.
1700 -h : print this help message and exit (with an error status).
1701 -r : reuse C symbols value if possible (skips costly nm extraction).
1702 -s : silent mode, only echoes questions and essential information.
1703 -D : define symbol to have some value:
1704 -D symbol symbol gets the value 'define'
1705 -D symbol=value symbol gets the value 'value'
1706 common used examples (see INSTALL for more info):
1707 -Duse64bitint use 64bit integers
1708 -Duse64bitall use 64bit integers and pointers
1709 -Dusethreads use thread support
1710 -Dinc_version_list=none do not include older perl trees in @INC
1711 -DEBUGGING=none DEBUGGING options
1712 -Dcc=gcc choose your compiler
1713 -Dprefix=/opt/perl5 choose your destination
1714 -E : stop at the end of questions, after having produced config.sh.
1715 -K : do not use unless you know what you are doing.
1716 -O : let -D and -U override definitions from loaded configuration file.
1717 -S : perform variable substitutions on all .SH files (can mix with -f)
1718 -U : undefine symbol:
1719 -U symbol symbol gets the value 'undef'
1720 -U symbol= symbol gets completely empty
1722 -A : manipulate symbol after the platform specific hints have been applied:
1723 -A append:symbol=value append value to symbol
1724 -A symbol=value like append:, but with a separating space
1725 -A define:symbol=value define symbol to have value
1726 -A clear:symbol define symbol to be ''
1727 -A define:symbol define symbol to be 'define'
1728 -A eval:symbol=value define symbol to be eval of value
1729 -A prepend:symbol=value prepend value to symbol
1730 -A undef:symbol define symbol to be 'undef'
1731 -A undef:symbol= define symbol to be ''
1732 e.g.: -A prepend:libswanted='cl pthread '
1733 -A ccflags=-DSOME_MACRO
1734 -V : print version number and exit (with a zero status).

2229 This installation shell script will examine your system and ask you questions
2230 to determine how the perl5 package should be installed. If you get
2231 stuck on a question, you may use a ! shell escape to start a subshell or
2232 execute a command. Many of the questions will have default answers in square
2233 brackets; typing carriage return will give you the default.
2235 On some of the questions which ask for file or directory names you are allowed
2236 to use the ~name construct to specify the login directory belonging to "name",
2237 even if you don't have a shell which knows about that. Questions where this is
2238 allowed will be marked "(~name ok)".
2242 dflt='Type carriage return to continue'
2246 The prompter used in this script allows you to use shell variables and
2247 backticks in your answers. You may use $1, $2, etc... to refer to the words
2248 in the default answer, as if the default line was a set of arguments given to a
2249 script shell. This means you may also use $* to repeat the whole default line,
2250 so you do not have to re-type everything to add something to the default.
2252 Everytime there is a substitution, you will have to confirm. If there is an
2253 error (e.g. an unmatched backtick), the default answer will remain unchanged
2254 and you will be prompted again.
2256 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2257 the questions and use the computed defaults (or the previous answers if there
2258 was already a config.sh file). Type 'Configure -h' for a list of options.
2259 You may also start interactively and then answer '& -d' at any prompt to turn
2260 on the non-interactive behaviour for the remainder of the execution.
2266 Much effort has been expended to ensure that this shell script will run on any
2267 Unix system. If despite that it blows up on yours, your best bet is to edit
2268 Configure and run it again. If you can't run Configure for some reason,
2269 you'll have to generate a config.sh file by hand. Whatever problems you
2270 have, let me (perlbug@perl.org) know how I blew it.
2272 This installation script affects things in two ways:
2274 1) it may do direct variable substitutions on some of the files included
2276 2) it builds a config.h file for inclusion in C programs. You may edit
2277 any of these files as the need arises after running this script.
2279 If you make a mistake on a question, there is no easy way to back up to it
2280 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2281 files. Configure will offer to let you do this before it runs the SH files.

8263 I need to select a good name for the shared libperl. If your system uses
8264 library names with major and minor numbers, then you might want something
8265 like $majmin. Alternatively, if your system uses a single version
8266 number for shared libraries, then you might want to use $majonly.
8267 Or, your system might be quite happy with a simple libperl.$so.
8269 Since the shared libperl will get installed into a version-specific
8270 architecture-dependent directory, the version number of the shared perl
8271 library probably isn't important, so the default should be o.k.
