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 | # | |
613d6c3e | 14 | # Note: this Configure script was generated automatically. Rather than |
2304df62 | 15 | # working with this copy of Configure, you may wish to get metaconfig. |

16 | # The dist package (which contains metaconfig) is available via SVN: |

20 | # Though this script was generated by metaconfig, it is OK to send | |
21 | # patches against it. It's up to the Configure pumpkin to backport | |
22 | # the patch to the metaunits if it is accepted. | |
23 | # See Porting/pumpkin.pod for more information on metaconfig. | |

34 | SCO csh still thinks true is false. Write to SCO today and tell them that next | |
35 | year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-) | |

37 | (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All | |
38 | we'd have to do is go in and swap the && and || tokens, wherever they are.) | |

2304df62 | 2216 | This installation shell script will examine your system and ask you questions |
a0d0e21e | 2217 | to determine how the perl5 package should be installed. If you get |
2304df62 AD |
2218 | stuck on a question, you may use a ! shell escape to start a subshell or |
2219 | execute a command. Many of the questions will have default answers in square | |
2220 | brackets; typing carriage return will give you the default. | |
2221 | ||
2222 | On some of the questions which ask for file or directory names you are allowed | |
2223 | to use the ~name construct to specify the login directory belonging to "name", | |
2224 | even if you don't have a shell which knows about that. Questions where this is | |
2225 | allowed will be marked "(~name ok)". | |

2231 | cat <<'EOH' | |
2232 | ||
2233 | The prompter used in this script allows you to use shell variables and | |
2234 | backticks in your answers. You may use $1, $2, etc... to refer to the words | |
2235 | in the default answer, as if the default line was a set of arguments given to a | |
2236 | script shell. This means you may also use $* to repeat the whole default line, | |
2237 | so you do not have to re-type everything to add something to the default. | |
2238 | ||
2239 | Everytime there is a substitution, you will have to confirm. If there is an | |
2240 | error (e.g. an unmatched backtick), the default answer will remain unchanged | |
2241 | and you will be prompted again. | |
2242 | ||
2243 | If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all | |
2244 | the questions and use the computed defaults (or the previous answers if there | |
2245 | was already a config.sh file). Type 'Configure -h' for a list of options. | |
ecfc5424 | 2246 | You may also start interactively and then answer '& -d' at any prompt to turn |
dfe9444c | 2247 | on the non-interactive behaviour for the remainder of the execution. |

2253 | Much effort has been expended to ensure that this shell script will run on any | |
2254 | Unix system. If despite that it blows up on yours, your best bet is to edit | |
40000a8c AD |
2255 | Configure and run it again. If you can't run Configure for some reason, |
2256 | you'll have to generate a config.sh file by hand. Whatever problems you | |
7f2de2d2 | 2257 | have, let me (perlbug@perl.org) know how I blew it. |
2304df62 AD |
2258 | |
2259 | This installation script affects things in two ways: | |
2260 | ||
2261 | 1) it may do direct variable substitutions on some of the files included | |
2262 | in this kit. | |
2263 | 2) it builds a config.h file for inclusion in C programs. You may edit | |
2264 | any of these files as the need arises after running this script. | |
2265 | ||
2266 | If you make a mistake on a question, there is no easy way to back up to it | |
2267 | currently. The easiest thing to do is to edit config.sh and rerun all the SH | |
2268 | files. Configure will offer to let you do this before it runs the SH files. | |

3469 | If you have a handcrafted Policy.sh file or a Policy.sh file generated by a |
3470 | previous run of Configure, you may specify it as well as or instead of | |
3471 | OS-specific hints. If hints are provided for your OS, you should use them: | |
3472 | although Perl can probably be built without hints on many platforms, using | |
3473 | hints often improve performance and may enable features that Configure can't | |
3474 | set up on its own. If there are no hints that match your OS, specify "none"; | |

7422 | I can use $nm to extract the symbols from your C libraries. This |
7423 | is a time consuming task which may generate huge output on the disk (up | |
7424 | to 3 megabytes) but that should make the symbols extraction faster. The | |
7425 | alternative is to skip the 'nm' extraction part and to compile a small | |
7426 | test program instead to determine whether each symbol is present. If | |
7427 | you have a fast C compiler and/or if your 'nm' output cannot be parsed, | |
7428 | this may be the best solution. | |
b4eb6b3d | 7429 | |
89ce900e | 7430 | You probably shouldn't let me use 'nm' if you are using the GNU C Library. |

9102 | Perl can be built to use 'fast stdio', which means using the stdio | |
9103 | library but also directly manipulating the stdio buffers to enable | |
9104 | faster I/O. Using stdio is better for backward compatibility (especially | |
9105 | for Perl extensions), but on the other hand since Perl 5.8 the 'perlio' | |
9106 | interface has been preferred instead of stdio. | |
9107 | ||
