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/Perl/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 from https://github.com/Perl/metaconfig
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!

1828 Usage: $me [-dehrsEKOSV] [-f config.sh] [-D symbol] [-D symbol=value]
1829 [-U symbol] [-U symbol=] [-A command:symbol...]
1830 -d : use defaults for all answers.
1831 -e : go on without questioning past the production of config.sh.
1832 -f : specify an alternate default configuration file.
1833 -h : print this help message and exit (with an error status).
1834 -r : reuse C symbols value if possible (skips costly nm extraction).
1835 -s : silent mode, only echoes questions and essential information.
1836 -D : define symbol to have some value:
1837 -D symbol symbol gets the value 'define'
1838 -D symbol=value symbol gets the value 'value'
1839 common used examples (see INSTALL for more info):
1840 -Duse64bitint use 64bit integers
1841 -Duse64bitall use 64bit integers and pointers
1842 -Dusethreads use thread support
1843 -Dinc_version_list=none do not include older perl trees in @INC
1844 -DEBUGGING=none DEBUGGING options
1845 -Dcc=gcc choose your compiler
1846 -Dprefix=/opt/perl5 choose your destination
1847 -E : stop at the end of questions, after having produced config.sh.
1848 -K : do not use unless you know what you are doing.
1849 -O : ignored for backward compatibility
1850 -S : perform variable substitutions on all .SH files (can mix with -f)
1851 -U : undefine symbol:
1852 -U symbol symbol gets the value 'undef'
1853 -U symbol= symbol gets completely empty
1855 -A : manipulate symbol after the platform specific hints have been applied:
1856 -A append:symbol=value append value to symbol
1857 -A symbol=value like append:, but with a separating space
1858 -A define:symbol=value define symbol to have value
1859 -A clear:symbol define symbol to be ''
1860 -A define:symbol define symbol to be 'define'
1861 -A eval:symbol=value define symbol to be eval of value
1862 -A prepend:symbol=value prepend value to symbol
1863 -A undef:symbol define symbol to be 'undef'
1864 -A undef:symbol= define symbol to be ''
1865 e.g.: -A prepend:libswanted='cl pthread '
1866 -A ccflags=-DSOME_MACRO
1867 -V : print version number and exit (with a zero status).

2367 This installation shell script will examine your system and ask you questions
2368 to determine how the perl5 package should be installed. If you get
2369 stuck on a question, you may use a ! shell escape to start a subshell or
2370 execute a command. Many of the questions will have default answers in square
2371 brackets; typing carriage return will give you the default.
2373 On some of the questions which ask for file or directory names you are allowed
2374 to use the ~name construct to specify the login directory belonging to "name",
2375 even if you don't have a shell which knows about that. Questions where this is
2376 allowed will be marked "(~name ok)".
2380 dflt='Type carriage return to continue'
2384 The prompter used in this script allows you to use shell variables and
2385 backticks in your answers. You may use $1, $2, etc... to refer to the words
2386 in the default answer, as if the default line was a set of arguments given to a
2387 script shell. This means you may also use $* to repeat the whole default line,
2388 so you do not have to re-type everything to add something to the default.
2390 Every time there is a substitution, you will have to confirm. If there is an
2391 error (e.g. an unmatched backtick), the default answer will remain unchanged
2392 and you will be prompted again.
2394 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2395 the questions and use the computed defaults (or the previous answers if there
2396 was already a config.sh file). Type 'Configure -h' for a list of options.
2397 You may also start interactively and then answer '& -d' at any prompt to turn
2398 on the non-interactive behaviour for the remainder of the execution.
2404 Much effort has been expended to ensure that this shell script will run on any
2405 Unix system. If despite that it blows up on yours, your best bet is to edit
2406 Configure and run it again. If you can't run Configure for some reason,
2407 you'll have to generate a config.sh file by hand. Whatever problems you
2408 have, let me (https://github.com/Perl/perl5/issues) know how I blew it.
2410 This installation script affects things in two ways:
2412 1) it may do direct variable substitutions on some of the files included
2414 2) it builds a config.h file for inclusion in C programs. You may edit
2415 any of these files as the need arises after running this script.
2417 If you make a mistake on a question, there is no easy way to back up to it
2418 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2419 files. Configure will offer to let you do this before it runs the SH files.
