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.
5#
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.)
10#
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.
13#
14# (Note: this Configure script was generated automatically. Rather than
15# working with this copy of Configure, you may wish to get metaconfig.
16# The dist-3.0 package (which contains metaconfig) was posted in
dfe9444c
AD
17# comp.sources.misc and is available on CPAN under authors/id/RAM so
18# you may fetch it yourself from your nearest archive site.)

29SCO csh still thinks true is false. Write to SCO today and tell them that next
30year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
31
32(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33we'd have to do is go in and swap the && and || tokens, wherever they are.)

40I will attempt to remedy the situation by running sh for you...

2304df62 1836This installation shell script will examine your system and ask you questions
a0d0e21e 1837to determine how the perl5 package should be installed. If you get
2304df62
AD
1838stuck on a question, you may use a ! shell escape to start a subshell or
1839execute a command. Many of the questions will have default answers in square
1840brackets; typing carriage return will give you the default.
1841
1842On some of the questions which ask for file or directory names you are allowed
1843to use the ~name construct to specify the login directory belonging to "name",
1844even if you don't have a shell which knows about that. Questions where this is
1845allowed will be marked "(~name ok)".
1846
1847EOH

1849 dflt='Type carriage return to continue'
1850 . ./myread
1851 cat <<'EOH'
1852
1853The prompter used in this script allows you to use shell variables and
1854backticks in your answers. You may use $1, $2, etc... to refer to the words
1855in the default answer, as if the default line was a set of arguments given to a
1856script shell. This means you may also use $* to repeat the whole default line,
1857so you do not have to re-type everything to add something to the default.
1858
1859Everytime there is a substitution, you will have to confirm. If there is an
1860error (e.g. an unmatched backtick), the default answer will remain unchanged
1861and you will be prompted again.
1862
1863If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1864the questions and use the computed defaults (or the previous answers if there
1865was already a config.sh file). Type 'Configure -h' for a list of options.
ecfc5424 1866You may also start interactively and then answer '& -d' at any prompt to turn
dfe9444c 1867on the non-interactive behaviour for the remainder of the execution.

1873Much effort has been expended to ensure that this shell script will run on any
1874Unix system. If despite that it blows up on yours, your best bet is to edit
40000a8c
AD
1875Configure and run it again. If you can't run Configure for some reason,
1876you'll have to generate a config.sh file by hand. Whatever problems you
7f2de2d2 1877have, let me (perlbug@perl.org) know how I blew it.

1878
1879This installation script affects things in two ways:
1880
18811) it may do direct variable substitutions on some of the files included
1882 in this kit.
18832) it builds a config.h file for inclusion in C programs. You may edit
1884 any of these files as the need arises after running this script.
1885
1886If you make a mistake on a question, there is no easy way to back up to it
1887currently. The easiest thing to do is to edit config.sh and rerun all the SH
1888files. Configure will offer to let you do this before it runs the SH files.
