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.) | |

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 | |
17 | # comp.sources.misc so you may fetch it yourself from your nearest | |
18 | # archive site. Check with Archie if you don't know where that can be.) | |

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

1356 | This installation shell script will examine your system and ask you questions | |
a0d0e21e | 1357 | to determine how the perl5 package should be installed. If you get |
2304df62 AD |
1358 | stuck on a question, you may use a ! shell escape to start a subshell or |
1359 | execute a command. Many of the questions will have default answers in square | |
1360 | brackets; typing carriage return will give you the default. | |
1361 | ||
1362 | On some of the questions which ask for file or directory names you are allowed | |
1363 | to use the ~name construct to specify the login directory belonging to "name", | |
1364 | even if you don't have a shell which knows about that. Questions where this is | |
1365 | allowed will be marked "(~name ok)". | |
1366 | ||

1371 | cat <<'EOH' | |
1372 | ||
1373 | The prompter used in this script allows you to use shell variables and | |
1374 | backticks in your answers. You may use $1, $2, etc... to refer to the words | |
1375 | in the default answer, as if the default line was a set of arguments given to a | |
1376 | script shell. This means you may also use $* to repeat the whole default line, | |
1377 | so you do not have to re-type everything to add something to the default. | |
1378 | ||
1379 | Everytime there is a substitution, you will have to confirm. If there is an | |
1380 | error (e.g. an unmatched backtick), the default answer will remain unchanged | |
1381 | and you will be prompted again. | |
1382 | ||
1383 | If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all | |
1384 | the questions and use the computed defaults (or the previous answers if there | |
1385 | was already a config.sh file). Type 'Configure -h' for a list of options. | |
ecfc5424 | 1386 | You may also start interactively and then answer '& -d' at any prompt to turn |
7bac28a0 | 1387 | on the non-interactive behavior for the remainder of the execution. |

1393 | Much effort has been expended to ensure that this shell script will run on any | |
1394 | Unix system. If despite that it blows up on yours, your best bet is to edit | |
40000a8c AD |
1395 | Configure and run it again. If you can't run Configure for some reason, |
1396 | you'll have to generate a config.sh file by hand. Whatever problems you | |
284c50cc | 1397 | have, let me (chip@perl.com) know how I blew it. |

1399 | This installation script affects things in two ways: | |
1400 | ||
1401 | 1) it may do direct variable substitutions on some of the files included | |
1402 | in this kit. | |
1403 | 2) it builds a config.h file for inclusion in C programs. You may edit | |
1404 | any of these files as the need arises after running this script. | |
1405 | ||
1406 | If you make a mistake on a question, there is no easy way to back up to it | |
1407 | currently. The easiest thing to do is to edit config.sh and rerun all the SH | |
1408 | files. Configure will offer to let you do this before it runs the SH files. | |

3051 | Some systems have different model sizes. On most systems they are called | |
3052 | small, medium, large, and huge. On the PDP11 they are called unsplit and | |
3053 | split. If your system doesn't support different memory models, say "none". | |
3054 | If you wish to force everything to one memory model, say "none" here and | |
3055 | put the appropriate flags later when it asks you for other cc and ld flags. | |
3056 | Venix systems may wish to put "none" and let the compiler figure things out. | |
