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 should use metaconfig. Perl uses a modified version of this
17 # tool, and this, together with the metaconfig units, are available
18 # in the git repository:
19 # $ git clone https://github.com/perl5-metaconfig/metaconfig metaconfig
20 # The original dist package (including metaconfig) is available on github:
21 # $ git clone https://github.com/rmanfredi/dist.git dist-git
23 # Though this script was generated by metaconfig from metaunits, it is
24 # OK to send patches against Configure itself (but not to commit them
25 # to blead). It's up to
26 # the Configure maintainers to backport the patch to the metaunits if it
27 # is accepted. Exceptions to this rule, and more information, is in
28 # Porting/pumpkin.pod.
30 # Generated using [metaconfig 3.5 PL0]
31 # (with additional metaconfig patches by perlbug@perl.org)
36 SCO csh still thinks true is false. Write to SCO today and tell them that next
37 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
39 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
40 we'd have to do is go in and swap the && and || tokens, wherever they are.)
42 [End of diatribe. We now return you to your regularly scheduled programming...]
46 OOPS! You naughty creature! You didn't run Configure with sh!

1823 Usage: $me [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
1824 [-U symbol] [-U symbol=] [-A command:symbol...]
1825 -d : use defaults for all answers.
1826 -e : go on without questioning past the production of config.sh.
1827 -f : specify an alternate default configuration file.
1828 -h : print this help message and exit (with an error status).
1829 -r : reuse C symbols value if possible (skips costly nm extraction).
1830 -s : silent mode, only echoes questions and essential information.
1831 -D : define symbol to have some value:
1832 -D symbol symbol gets the value 'define'
1833 -D symbol=value symbol gets the value 'value'
1834 common used examples (see INSTALL for more info):
1835 -Duse64bitint use 64bit integers
1836 -Duse64bitall use 64bit integers and pointers
1837 -Dusethreads use thread support
1838 -Dinc_version_list=none do not include older perl trees in @INC
1839 -DEBUGGING=none DEBUGGING options
1840 -Dcc=gcc choose your compiler
1841 -Dprefix=/opt/perl5 choose your destination
1842 -E : stop at the end of questions, after having produced config.sh.
1843 -K : do not use unless you know what you are doing.
1844 -O : ignored for backward compatibility
1845 -S : perform variable substitutions on all .SH files (can mix with -f)
1846 -U : undefine symbol:
1847 -U symbol symbol gets the value 'undef'
1848 -U symbol= symbol gets completely empty
1850 -A : manipulate symbol after the platform specific hints have been applied:
1851 -A append:symbol=value append value to symbol
1852 -A symbol=value like append:, but with a separating space
1853 -A define:symbol=value define symbol to have value
1854 -A clear:symbol define symbol to be ''
1855 -A define:symbol define symbol to be 'define'
1856 -A eval:symbol=value define symbol to be eval of value
1857 -A prepend:symbol=value prepend value to symbol
1858 -A undef:symbol define symbol to be 'undef'
1859 -A undef:symbol= define symbol to be ''
1860 e.g.: -A prepend:libswanted='cl pthread '
1861 -A ccflags=-DSOME_MACRO
1862 -V : print version number and exit (with a zero status).

2361 This installation shell script will examine your system and ask you questions
2362 to determine how the perl5 package should be installed. If you get
2363 stuck on a question, you may use a ! shell escape to start a subshell or
2364 execute a command. Many of the questions will have default answers in square
2365 brackets; typing carriage return will give you the default.
2367 On some of the questions which ask for file or directory names you are allowed
2368 to use the ~name construct to specify the login directory belonging to "name",
2369 even if you don't have a shell which knows about that. Questions where this is
2370 allowed will be marked "(~name ok)".
2374 dflt='Type carriage return to continue'
2378 The prompter used in this script allows you to use shell variables and
2379 backticks in your answers. You may use $1, $2, etc... to refer to the words
2380 in the default answer, as if the default line was a set of arguments given to a
2381 script shell. This means you may also use $* to repeat the whole default line,
2382 so you do not have to re-type everything to add something to the default.
2384 Every time there is a substitution, you will have to confirm. If there is an
2385 error (e.g. an unmatched backtick), the default answer will remain unchanged
2386 and you will be prompted again.
2388 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2389 the questions and use the computed defaults (or the previous answers if there
2390 was already a config.sh file). Type 'Configure -h' for a list of options.
2391 You may also start interactively and then answer '& -d' at any prompt to turn
2392 on the non-interactive behaviour for the remainder of the execution.
2398 Much effort has been expended to ensure that this shell script will run on any
2399 Unix system. If despite that it blows up on yours, your best bet is to edit
2400 Configure and run it again. If you can't run Configure for some reason,
2401 you'll have to generate a config.sh file by hand. Whatever problems you
2402 have, let me (perlbug@perl.org) know how I blew it.
2404 This installation script affects things in two ways:
2406 1) it may do direct variable substitutions on some of the files included
2408 2) it builds a config.h file for inclusion in C programs. You may edit
2409 any of these files as the need arises after running this script.
2411 If you make a mistake on a question, there is no easy way to back up to it
2412 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2413 files. Configure will offer to let you do this before it runs the SH files.

4722 the operating system because otherwise serious problems

4725 I'm trying to be optimistic here, though, and will continue.
