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 by the tool
15 # called "metaconfig". Rather than working with this copy of Configure,
16 # you may wish to get metaconfig. Perl uses a modified version of this
17 # tool, available in the "dist" folder in the checkout of the git repo
18 # $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
19 # The original dist package (including metaconfig) is available via SVN:
20 # $ svn co https://svn.code.sf.net/p/dist/code/trunk/dist
22 # Though this script was generated by metaconfig from metaunits, it is
23 # OK to send patches against Configure itself. It's up to the Configure
24 # pumpkin to backport the patch to the metaunits if it is accepted.
25 # For more information on patching Configure, see pod/perlhack.pod
27 # The metaunits are also available from the public git repository:
28 # http://perl5.git.perl.org/metaconfig.git/ or
29 # $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
31 # See Porting/pumpkin.pod for more information on metaconfig.
33 # Generated using [metaconfig 3.5 PL0]
34 # (with additional metaconfig patches by perlbug@perl.org)
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...]

1800 Usage: $me [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
1801 [-U symbol] [-U symbol=] [-A command:symbol...]
1802 -d : use defaults for all answers.
1803 -e : go on without questioning past the production of config.sh.
1804 -f : specify an alternate default configuration file.
1805 -h : print this help message and exit (with an error status).
1806 -r : reuse C symbols value if possible (skips costly nm extraction).
1807 -s : silent mode, only echoes questions and essential information.
1808 -D : define symbol to have some value:
1809 -D symbol symbol gets the value 'define'
1810 -D symbol=value symbol gets the value 'value'
1811 common used examples (see INSTALL for more info):
1812 -Duse64bitint use 64bit integers
1813 -Duse64bitall use 64bit integers and pointers
1814 -Dusethreads use thread support
1815 -Dinc_version_list=none do not include older perl trees in @INC
1816 -DEBUGGING=none DEBUGGING options
1817 -Dcc=gcc choose your compiler
1818 -Dprefix=/opt/perl5 choose your destination
1819 -E : stop at the end of questions, after having produced config.sh.
1820 -K : do not use unless you know what you are doing.
1821 -O : let -D and -U override definitions from loaded configuration file.
1822 -S : perform variable substitutions on all .SH files (can mix with -f)
1823 -U : undefine symbol:
1824 -U symbol symbol gets the value 'undef'
1825 -U symbol= symbol gets completely empty
1827 -A : manipulate symbol after the platform specific hints have been applied:
1828 -A append:symbol=value append value to symbol
1829 -A symbol=value like append:, but with a separating space
1830 -A define:symbol=value define symbol to have value
1831 -A clear:symbol define symbol to be ''
1832 -A define:symbol define symbol to be 'define'
1833 -A eval:symbol=value define symbol to be eval of value
1834 -A prepend:symbol=value prepend value to symbol
1835 -A undef:symbol define symbol to be 'undef'
1836 -A undef:symbol= define symbol to be ''
1837 e.g.: -A prepend:libswanted='cl pthread '
1838 -A ccflags=-DSOME_MACRO
1839 -V : print version number and exit (with a zero status).

2339 This installation shell script will examine your system and ask you questions
2340 to determine how the perl5 package should be installed. If you get
2341 stuck on a question, you may use a ! shell escape to start a subshell or
2342 execute a command. Many of the questions will have default answers in square
2343 brackets; typing carriage return will give you the default.
2345 On some of the questions which ask for file or directory names you are allowed
2346 to use the ~name construct to specify the login directory belonging to "name",
2347 even if you don't have a shell which knows about that. Questions where this is
2348 allowed will be marked "(~name ok)".
2352 dflt='Type carriage return to continue'
2356 The prompter used in this script allows you to use shell variables and
2357 backticks in your answers. You may use $1, $2, etc... to refer to the words
2358 in the default answer, as if the default line was a set of arguments given to a
2359 script shell. This means you may also use $* to repeat the whole default line,
2360 so you do not have to re-type everything to add something to the default.
2362 Every time there is a substitution, you will have to confirm. If there is an
2363 error (e.g. an unmatched backtick), the default answer will remain unchanged
2364 and you will be prompted again.
2366 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2367 the questions and use the computed defaults (or the previous answers if there
2368 was already a config.sh file). Type 'Configure -h' for a list of options.
2369 You may also start interactively and then answer '& -d' at any prompt to turn
2370 on the non-interactive behaviour for the remainder of the execution.
2376 Much effort has been expended to ensure that this shell script will run on any
2377 Unix system. If despite that it blows up on yours, your best bet is to edit
2378 Configure and run it again. If you can't run Configure for some reason,
2379 you'll have to generate a config.sh file by hand. Whatever problems you
2380 have, let me (perlbug@perl.org) know how I blew it.
2382 This installation script affects things in two ways:
2384 1) it may do direct variable substitutions on some of the files included
2386 2) it builds a config.h file for inclusion in C programs. You may edit
2387 any of these files as the need arises after running this script.
2389 If you make a mistake on a question, there is no easy way to back up to it
2390 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2391 files. Configure will offer to let you do this before it runs the SH files.
