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. | |
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.) | |

29 | SCO csh still thinks true is false. Write to SCO today and tell them that next | |
30 | year 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 | |
33 | we'd have to do is go in and swap the && and || tokens, wherever they are.) | |

1760 | backticks in your answers. You may use $1, $2, etc... to refer to the words | |
1761 | in the default answer, as if the default line was a set of arguments given to a | |
1762 | script shell. This means you may also use $* to repeat the whole default line, | |
1763 | so you do not have to re-type everything to add something to the default. | |
1764 | ||
1765 | Everytime there is a substitution, you will have to confirm. If there is an | |
1766 | error (e.g. an unmatched backtick), the default answer will remain unchanged | |
1767 | and you will be prompted again. | |
1768 | ||
1769 | If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all | |
1770 | the questions and use the computed defaults (or the previous answers if there | |
1771 | was already a config.sh file). Type 'Configure -h' for a list of options. | |
ecfc5424 | 1772 | You may also start interactively and then answer '& -d' at any prompt to turn |
dfe9444c | 1773 | on the non-interactive behaviour for the remainder of the execution. |

1779 | Much effort has been expended to ensure that this shell script will run on any | |
1780 | Unix system. If despite that it blows up on yours, your best bet is to edit | |
40000a8c AD |
1781 | Configure and run it again. If you can't run Configure for some reason, |
1782 | you'll have to generate a config.sh file by hand. Whatever problems you | |
46193409 | 1783 | have, let me (perlbug@perl.com) know how I blew it. |

1785 | This installation script affects things in two ways: | |
1786 | ||
1787 | 1) it may do direct variable substitutions on some of the files included | |
1788 | in this kit. | |
1789 | 2) it builds a config.h file for inclusion in C programs. You may edit | |
1790 | any of these files as the need arises after running this script. | |
1791 | ||
1792 | If you make a mistake on a question, there is no easy way to back up to it | |
1793 | currently. The easiest thing to do is to edit config.sh and rerun all the SH | |
1794 | files. Configure will offer to let you do this before it runs the SH files. | |

4829 | secure. Some sites have disabled setuid #! scripts because of this. | |

4831 | First let's decide if your kernel supports secure setuid #! scripts. |

7077 | Previous version of $package used the standard IO mechanisms as defined |
7078 | in <stdio.h>. Versions 5.003_02 and later of perl allow alternate IO | |
2afac517 | 7079 | mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still |
85aff577 CS |
7080 | the default. This abstraction layer can use AT&T's sfio (if you already |
7081 | have sfio installed) or regular stdio. Using PerlIO with sfio may cause | |
