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!

1814 [-U symbol] [-U symbol=] [-A command:symbol...]
1815 -d : use defaults for all answers.
1816 -e : go on without questioning past the production of config.sh.
1817 -f : specify an alternate default configuration file.
1818 -h : print this help message and exit (with an error status).
1819 -r : reuse C symbols value if possible (skips costly nm extraction).
1820 -s : silent mode, only echoes questions and essential information.
1821 -D : define symbol to have some value:
1822 -D symbol symbol gets the value 'define'
1823 -D symbol=value symbol gets the value 'value'
1824 common used examples (see INSTALL for more info):
1825 -Duse64bitint use 64bit integers
1826 -Duse64bitall use 64bit integers and pointers
1827 -Dusethreads use thread support
1828 -Dinc_version_list=none do not include older perl trees in @INC
1829 -DEBUGGING=none DEBUGGING options
1830 -Dcc=gcc choose your compiler
1831 -Dprefix=/opt/perl5 choose your destination
1832 -E : stop at the end of questions, after having produced config.sh.
1833 -K : do not use unless you know what you are doing.
1834 -O : ignored for backward compatibility
1835 -S : perform variable substitutions on all .SH files (can mix with -f)
1836 -U : undefine symbol:
1837 -U symbol symbol gets the value 'undef'
1838 -U symbol= symbol gets completely empty
1840 -A : manipulate symbol after the platform specific hints have been applied:
1841 -A append:symbol=value append value to symbol
1842 -A symbol=value like append:, but with a separating space
1843 -A define:symbol=value define symbol to have value
1844 -A clear:symbol define symbol to be ''
1845 -A define:symbol define symbol to be 'define'
1846 -A eval:symbol=value define symbol to be eval of value
1847 -A prepend:symbol=value prepend value to symbol
1848 -A undef:symbol define symbol to be 'undef'
1849 -A undef:symbol= define symbol to be ''
1850 e.g.: -A prepend:libswanted='cl pthread '
1851 -A ccflags=-DSOME_MACRO
1852 -V : print version number and exit (with a zero status).

2351 This installation shell script will examine your system and ask you questions
2352 to determine how the perl5 package should be installed. If you get
2353 stuck on a question, you may use a ! shell escape to start a subshell or
2354 execute a command. Many of the questions will have default answers in square
2355 brackets; typing carriage return will give you the default.
2357 On some of the questions which ask for file or directory names you are allowed
2358 to use the ~name construct to specify the login directory belonging to "name",
2359 even if you don't have a shell which knows about that. Questions where this is
2360 allowed will be marked "(~name ok)".
2364 dflt='Type carriage return to continue'
2368 The prompter used in this script allows you to use shell variables and
2369 backticks in your answers. You may use $1, $2, etc... to refer to the words
2370 in the default answer, as if the default line was a set of arguments given to a
2371 script shell. This means you may also use $* to repeat the whole default line,
2372 so you do not have to re-type everything to add something to the default.
2374 Every time there is a substitution, you will have to confirm. If there is an
2375 error (e.g. an unmatched backtick), the default answer will remain unchanged
2376 and you will be prompted again.
2378 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2379 the questions and use the computed defaults (or the previous answers if there
2380 was already a config.sh file). Type 'Configure -h' for a list of options.
2381 You may also start interactively and then answer '& -d' at any prompt to turn
2382 on the non-interactive behaviour for the remainder of the execution.
2388 Much effort has been expended to ensure that this shell script will run on any
2389 Unix system. If despite that it blows up on yours, your best bet is to edit
2390 Configure and run it again. If you can't run Configure for some reason,
2391 you'll have to generate a config.sh file by hand. Whatever problems you
2392 have, let me (perlbug@perl.org) know how I blew it.
2394 This installation script affects things in two ways:
2396 1) it may do direct variable substitutions on some of the files included
2398 2) it builds a config.h file for inclusion in C programs. You may edit
2399 any of these files as the need arises after running this script.
2401 If you make a mistake on a question, there is no easy way to back up to it
2402 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2403 files. Configure will offer to let you do this before it runs the SH files.

4702 your operating system ($gccosandvers versus $osname$osvers).
4704 In general it is a good idea to keep gcc synchronized with
4705 the operating system because otherwise serious problems
4706 may ensue when trying to compile software, like Perl.
4708 I'm trying to be optimistic here, though, and will continue.
4709 If later during the configuration and build icky compilation
4710 problems appear (headerfile conflicts being the most common

4712 your operating system release.
