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.) | |

2304df62 | 1823 | This installation shell script will examine your system and ask you questions |
a0d0e21e | 1824 | to determine how the perl5 package should be installed. If you get |
2304df62 AD |
1825 | stuck on a question, you may use a ! shell escape to start a subshell or |
1826 | execute a command. Many of the questions will have default answers in square | |
1827 | brackets; typing carriage return will give you the default. | |
1828 | ||
1829 | On some of the questions which ask for file or directory names you are allowed | |
1830 | to use the ~name construct to specify the login directory belonging to "name", | |
1831 | even if you don't have a shell which knows about that. Questions where this is | |
1832 | allowed will be marked "(~name ok)". | |
1833 | ||

1838 | cat <<'EOH' | |
1839 | ||
1840 | The prompter used in this script allows you to use shell variables and | |
1841 | backticks in your answers. You may use $1, $2, etc... to refer to the words | |
1842 | in the default answer, as if the default line was a set of arguments given to a | |
1843 | script shell. This means you may also use $* to repeat the whole default line, | |
1844 | so you do not have to re-type everything to add something to the default. | |
1845 | ||
1846 | Everytime there is a substitution, you will have to confirm. If there is an | |
1847 | error (e.g. an unmatched backtick), the default answer will remain unchanged | |
1848 | and you will be prompted again. | |
1849 | ||
1850 | If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all | |
1851 | the questions and use the computed defaults (or the previous answers if there | |
1852 | was already a config.sh file). Type 'Configure -h' for a list of options. | |
ecfc5424 | 1853 | You may also start interactively and then answer '& -d' at any prompt to turn |
dfe9444c | 1854 | on the non-interactive behaviour for the remainder of the execution. |

1860 | Much effort has been expended to ensure that this shell script will run on any | |
1861 | Unix system. If despite that it blows up on yours, your best bet is to edit | |
40000a8c AD |
1862 | Configure and run it again. If you can't run Configure for some reason, |
1863 | you'll have to generate a config.sh file by hand. Whatever problems you | |
46193409 | 1864 | have, let me (perlbug@perl.com) know how I blew it. |

1865 | |
1866 | This installation script affects things in two ways: | |
1867 | ||
1868 | 1) it may do direct variable substitutions on some of the files included | |
1869 | in this kit. | |
1870 | 2) it builds a config.h file for inclusion in C programs. You may edit | |
1871 | any of these files as the need arises after running this script. | |
1872 | ||
1873 | If you make a mistake on a question, there is no easy way to back up to it | |
1874 | currently. The easiest thing to do is to edit config.sh and rerun all the SH | |
1875 | files. Configure will offer to let you do this before it runs the SH files. | |

7468 | Previous version of $package used the standard IO mechanisms as defined |
7469 | in <stdio.h>. Versions 5.003_02 and later of perl allow alternate IO | |
2afac517 | 7470 | mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still |
85aff577 CS |
7471 | the default. This abstraction layer can use AT&T's sfio (if you already |
7472 | have sfio installed) or regular stdio. Using PerlIO with sfio may cause | |
7473 | problems with some extension modules. Using PerlIO with stdio is safe, | |
7474 | but it is slower than plain stdio and therefore is not the default. | |
