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
20 # Though this script was generated by metaconfig, it is OK to send
21 # patches against it. It's up to the Configure pumpkin to backport
22 # the patch to the metaunits if it is accepted.
23 # See Porting/pumpkin.pod for more information on metaconfig.

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

1662 Usage: $me [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
1663 [-U symbol] [-U symbol=] [-A command:symbol...]
1664 -d : use defaults for all answers.
1665 -e : go on without questioning past the production of config.sh.
1666 -f : specify an alternate default configuration file.
1667 -h : print this help message and exit (with an error status).
1668 -r : reuse C symbols value if possible (skips costly nm extraction).
1669 -s : silent mode, only echoes questions and essential information.
1670 -D : define symbol to have some value:
1671 -D symbol symbol gets the value 'define'
1672 -D symbol=value symbol gets the value 'value'
1673 common used examples (see INSTALL for more info):
1674 -Duse64bitint use 64bit integers
1675 -Duse64bitall use 64bit integers and pointers
1676 -Dusethreads use thread support
1677 -Dinc_version_list=none do not include older perl trees in @INC
1678 -DEBUGGING=none DEBUGGING options
1679 -Dcc=gcc choose your compiler
1680 -Dprefix=/opt/perl5 choose your destination
1681 -E : stop at the end of questions, after having produced config.sh.
1682 -K : do not use unless you know what you are doing.
1683 -O : let -D and -U override definitions from loaded configuration file.
1684 -S : perform variable substitutions on all .SH files (can mix with -f)
1685 -U : undefine symbol:
1686 -U symbol symbol gets the value 'undef'
1687 -U symbol= symbol gets completely empty
1689 -A : manipulate symbol after the platform specific hints have been applied:
1690 -A append:symbol=value append value to symbol
1691 -A symbol=value like append:, but with a separating space
1692 -A define:symbol=value define symbol to have value
1693 -A clear:symbol define symbol to be ''
1694 -A define:symbol define symbol to be 'define'
1695 -A eval:symbol=value define symbol to be eval of value
1696 -A prepend:symbol=value prepend value to symbol
1697 -A undef:symbol define symbol to be 'undef'
1698 -A undef:symbol= define symbol to be ''
1699 e.g.: -A prepend:libswanted='cl pthread '
1700 -A ccflags=-DSOME_MACRO
1701 -V : print version number and exit (with a zero status).

2192 This installation shell script will examine your system and ask you questions
2193 to determine how the perl5 package should be installed. If you get
2194 stuck on a question, you may use a ! shell escape to start a subshell or
2195 execute a command. Many of the questions will have default answers in square
2196 brackets; typing carriage return will give you the default.
2198 On some of the questions which ask for file or directory names you are allowed
2199 to use the ~name construct to specify the login directory belonging to "name",
2200 even if you don't have a shell which knows about that. Questions where this is
2201 allowed will be marked "(~name ok)".
2205 dflt='Type carriage return to continue'
2209 The prompter used in this script allows you to use shell variables and
2210 backticks in your answers. You may use $1, $2, etc... to refer to the words
2211 in the default answer, as if the default line was a set of arguments given to a
2212 script shell. This means you may also use $* to repeat the whole default line,
2213 so you do not have to re-type everything to add something to the default.
2215 Everytime there is a substitution, you will have to confirm. If there is an
2216 error (e.g. an unmatched backtick), the default answer will remain unchanged
2217 and you will be prompted again.
2219 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2220 the questions and use the computed defaults (or the previous answers if there
2221 was already a config.sh file). Type 'Configure -h' for a list of options.
2222 You may also start interactively and then answer '& -d' at any prompt to turn
2223 on the non-interactive behaviour for the remainder of the execution.
2229 Much effort has been expended to ensure that this shell script will run on any
2230 Unix system. If despite that it blows up on yours, your best bet is to edit
2231 Configure and run it again. If you can't run Configure for some reason,
2232 you'll have to generate a config.sh file by hand. Whatever problems you
2233 have, let me (perlbug@perl.org) know how I blew it.
2235 This installation script affects things in two ways:
2237 1) it may do direct variable substitutions on some of the files included
2239 2) it builds a config.h file for inclusion in C programs. You may edit
2240 any of these files as the need arises after running this script.
2242 If you make a mistake on a question, there is no easy way to back up to it
2243 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2244 files. Configure will offer to let you do this before it runs the SH files.

7285 I can use $nm to extract the symbols from your C libraries. This
7286 is a time consuming task which may generate huge output on the disk (up
7287 to 3 megabytes) but that should make the symbols extraction faster. The
7288 alternative is to skip the 'nm' extraction part and to compile a small
7289 test program instead to determine whether each symbol is present. If
