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.) | |

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.) | |

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

2304df62 | 1854 | This installation shell script will examine your system and ask you questions |
a0d0e21e | 1855 | to determine how the perl5 package should be installed. If you get |
2304df62 AD |
1856 | stuck on a question, you may use a ! shell escape to start a subshell or |
1857 | execute a command. Many of the questions will have default answers in square | |
1858 | brackets; typing carriage return will give you the default. | |
1859 | ||
1860 | On some of the questions which ask for file or directory names you are allowed | |
1861 | to use the ~name construct to specify the login directory belonging to "name", | |
1862 | even if you don't have a shell which knows about that. Questions where this is | |
1863 | allowed will be marked "(~name ok)". | |

1871 | The prompter used in this script allows you to use shell variables and | |
1872 | backticks in your answers. You may use $1, $2, etc... to refer to the words | |
1873 | in the default answer, as if the default line was a set of arguments given to a | |
1874 | script shell. This means you may also use $* to repeat the whole default line, | |
1875 | so you do not have to re-type everything to add something to the default. | |
1876 | ||
1877 | Everytime there is a substitution, you will have to confirm. If there is an | |
1878 | error (e.g. an unmatched backtick), the default answer will remain unchanged | |
1879 | and you will be prompted again. | |
1880 | ||
1881 | If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all | |
1882 | the questions and use the computed defaults (or the previous answers if there | |
1883 | was already a config.sh file). Type 'Configure -h' for a list of options. | |
ecfc5424 | 1884 | You may also start interactively and then answer '& -d' at any prompt to turn |
dfe9444c | 1885 | on the non-interactive behaviour for the remainder of the execution. |

1892 | Unix system. If despite that it blows up on yours, your best bet is to edit | |
40000a8c AD |
1893 | Configure and run it again. If you can't run Configure for some reason, |
1894 | you'll have to generate a config.sh file by hand. Whatever problems you | |
7f2de2d2 | 1895 | have, let me (perlbug@perl.org) know how I blew it. |

1897 | This installation script affects things in two ways: | |
1898 | ||
1899 | 1) it may do direct variable substitutions on some of the files included | |
1900 | in this kit. | |
1901 | 2) it builds a config.h file for inclusion in C programs. You may edit | |
1902 | any of these files as the need arises after running this script. | |
1903 | ||
1904 | If you make a mistake on a question, there is no easy way to back up to it | |
1905 | currently. The easiest thing to do is to edit config.sh and rerun all the SH | |
1906 | files. Configure will offer to let you do this before it runs the SH files. | |

3181 | Your gcc has not been compiled for the exact release of | |
3182 | your operating system ($gccosandvers versus $osname$osvers). | |
3183 | ||
3184 | In general it is a good idea to keep gcc synchronized with | |
3185 | the operating system because otherwise serious problems | |
3186 | may ensue when trying to compile software, like Perl. | |
3187 | ||
3188 | I'm trying to be optimistic here, though, and will continue. | |
3189 | If later during the configuration and build icky compilation | |

3190 | problems appear (headerfile conflicts being the most common |
3191 | manifestation), I suggest reinstalling the gcc to match | |

4029 | Your C compiler may want other flags. For this question you should include |
4030 | -I/whatever and -DWHATEVER flags and any other flags used by the C compiler, | |
4031 | but you should NOT include libraries or ld flags like -lwhatever. If you | |
4032 | want $package to honor its debug switch, you should include -DDEBUGGING here. | |
4033 | Your C compiler might also need additional flags, such as -D_POSIX_SOURCE. | |

4765 | I can use $nm to extract the symbols from your C libraries. This |
4766 | is a time consuming task which may generate huge output on the disk (up | |

4768 | alternative is to skip the 'nm' extraction part and to compile a small | |
4769 | test program instead to determine whether each symbol is present. If | |

6814 | I need to select a good name for the shared libperl. If your system uses | |
6815 | library names with major and minor numbers, then you might want something | |
6816 | like $majmin. Alternatively, if your system uses a single version | |
6817 | number for shared libraries, then you might want to use $majonly. | |
6818 | Or, your system might be quite happy with a simple libperl.$so. | |
6819 | ||
6820 | Since the shared libperl will get installed into a version-specific | |
6821 | architecture-dependent directory, the version number of the shared perl | |
6822 | library probably isn't important, so the default should be o.k. | |
