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!

1816 [-U symbol] [-U symbol=] [-A command:symbol...]
1817 -d : use defaults for all answers.
1818 -e : go on without questioning past the production of config.sh.
1819 -f : specify an alternate default configuration file.
1820 -h : print this help message and exit (with an error status).
1821 -r : reuse C symbols value if possible (skips costly nm extraction).
1822 -s : silent mode, only echoes questions and essential information.
1823 -D : define symbol to have some value:
1824 -D symbol symbol gets the value 'define'
1825 -D symbol=value symbol gets the value 'value'
1826 common used examples (see INSTALL for more info):
1827 -Duse64bitint use 64bit integers
1828 -Duse64bitall use 64bit integers and pointers
1829 -Dusethreads use thread support
1830 -Dinc_version_list=none do not include older perl trees in @INC
1831 -DEBUGGING=none DEBUGGING options
1832 -Dcc=gcc choose your compiler
1833 -Dprefix=/opt/perl5 choose your destination
1834 -E : stop at the end of questions, after having produced config.sh.
1835 -K : do not use unless you know what you are doing.
1836 -O : ignored for backward compatibility
1837 -S : perform variable substitutions on all .SH files (can mix with -f)
1838 -U : undefine symbol:
1839 -U symbol symbol gets the value 'undef'
1840 -U symbol= symbol gets completely empty
1842 -A : manipulate symbol after the platform specific hints have been applied:
1843 -A append:symbol=value append value to symbol
1844 -A symbol=value like append:, but with a separating space
1845 -A define:symbol=value define symbol to have value
1846 -A clear:symbol define symbol to be ''
1847 -A define:symbol define symbol to be 'define'
1848 -A eval:symbol=value define symbol to be eval of value
1849 -A prepend:symbol=value prepend value to symbol
1850 -A undef:symbol define symbol to be 'undef'
1851 -A undef:symbol= define symbol to be ''
1852 e.g.: -A prepend:libswanted='cl pthread '
1853 -A ccflags=-DSOME_MACRO
1854 -V : print version number and exit (with a zero status).

2353 This installation shell script will examine your system and ask you questions
2354 to determine how the perl5 package should be installed. If you get
2355 stuck on a question, you may use a ! shell escape to start a subshell or
2356 execute a command. Many of the questions will have default answers in square
2357 brackets; typing carriage return will give you the default.
2359 On some of the questions which ask for file or directory names you are allowed
2360 to use the ~name construct to specify the login directory belonging to "name",
2361 even if you don't have a shell which knows about that. Questions where this is
2362 allowed will be marked "(~name ok)".
2366 dflt='Type carriage return to continue'
2370 The prompter used in this script allows you to use shell variables and
2371 backticks in your answers. You may use $1, $2, etc... to refer to the words
2372 in the default answer, as if the default line was a set of arguments given to a
2373 script shell. This means you may also use $* to repeat the whole default line,
2374 so you do not have to re-type everything to add something to the default.
2376 Every time there is a substitution, you will have to confirm. If there is an
2377 error (e.g. an unmatched backtick), the default answer will remain unchanged
2378 and you will be prompted again.
2380 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
2381 the questions and use the computed defaults (or the previous answers if there
2382 was already a config.sh file). Type 'Configure -h' for a list of options.
2383 You may also start interactively and then answer '& -d' at any prompt to turn
2384 on the non-interactive behaviour for the remainder of the execution.
2390 Much effort has been expended to ensure that this shell script will run on any
2391 Unix system. If despite that it blows up on yours, your best bet is to edit
2392 Configure and run it again. If you can't run Configure for some reason,
2393 you'll have to generate a config.sh file by hand. Whatever problems you
2394 have, let me (perlbug@perl.org) know how I blew it.
2396 This installation script affects things in two ways:
2398 1) it may do direct variable substitutions on some of the files included
2400 2) it builds a config.h file for inclusion in C programs. You may edit
2401 any of these files as the need arises after running this script.
2403 If you make a mistake on a question, there is no easy way to back up to it
2404 currently. The easiest thing to do is to edit config.sh and rerun all the SH
2405 files. Configure will offer to let you do this before it runs the SH files.

4704 your operating system ($gccosandvers versus $osname$osvers).
4706 In general it is a good idea to keep gcc synchronized with
4707 the operating system because otherwise serious problems
4708 may ensue when trying to compile software, like Perl.
4710 I'm trying to be optimistic here, though, and will continue.
4711 If later during the configuration and build icky compilation
4712 problems appear (headerfile conflicts being the most common

4714 your operating system release.
