2 | Perl5 Metaconfig Units | |
3 | ||
4 | Copyright (c) 1996-1998, Andy Dougherty | |
5 | All rights reserved. | |
6 | ||
7 | These units are the ones I used to build Configure and config_h.SH | |
8 | in the Perl5 distribution. | |
9 | ||
10 | The Configure script and config_h.SH file in the Perl distribution are | |
11 | generated by a program called metaconfig. To run metaconfig, you will | |
12 | need the full dist 3.0 distribution, maintained by Raphael Manfredi. | |
13 | As of this writing, the current version is dist3.0, patchlevel 70. | |
14 | Dist version dist-3.0@70.tar.gz is available on CPAN (the Comprehensive | |
15 | Perl Archive Network) as | |
16 | <http://www.perl.com/perl/CPAN/authors/id/RAM/dist-3.0@70.tar.gz>. | |
17 | ||
18 | Instructions: | |
19 | ||
20 | 1. Unpack the full perl5 sources. Execute the following command | |
21 | ||
22 | chmod +w Configure config_h.SH Porting/Glossary Porting/config* | |
23 | ||
24 | 2. Unpack the archive containing this file in the perl5 source | |
25 | directory. This will create a directory 'U' under the perl5 | |
26 | sources. That directory will contain the metaconfig units for perl5. | |
27 | This will also create two files in the perl5 source tree: | |
28 | MANIFEST.new and .package. | |
29 | ||
30 | 3. Apply any patches to perl in the U/perl_patches directory. | |
31 | (This may well be empty.) | |
32 | ||
33 | 4a. Obtain dist-3.0pl70. | |
34 | ||
35 | 4b. Apply any patches to dist under the U/dist_patches subdirectory. | |
36 | ||
37 | 4c. Install dist. | |
38 | ||
39 | 5. From your main perl5 source directory, run packinit to | |
40 | regenerate the .package file. IMPORTANT: Change the name and | |
41 | address of the maintainer to your own name and address. I don't | |
42 | want bug reports intended for you coming to me. | |
43 | ||
44 | 6. From your main perl5 source directory, run | |
45 | ||
46 | metaconfig -m | |
47 | ||
48 | 7. Edit U/mkglossary to point to your dist-3.0pl70 location | |
49 | (See comments at the top.) | |
50 | ||
51 | 8. Run the U/mksample script to update the contents of the Porting/ | |
52 | subdirectory. | |
53 | ||
54 | 9. Let me know about any changes, corrections, or enhancements. | |
55 | ||
56 | Things to watch out for: | |
57 | ||
58 | 1. The Configure in 5.005 is a hand-patched version of that supplied | |
59 | with perl5.004_74 or so. Most of the patches had to do with | |
60 | supporting MPE/iX and EBCDIC systems. I have re-integrated most | |
61 | of the changes back into metaconfig, but I don't really undertand | |
62 | why MPE/iX needed some of the patches, so I may have missed | |
63 | something important. I did try to flag questionable changes in | |
64 | the individual units. | |
65 | ||
66 | 2. Future support of better random number generators should probably | |
67 | start with the randfunc.U unit included here. It's currently | |
68 | broken, but well commented and probably a good place to start. | |
69 | ||
70 | Descriptions: | |
71 | ||
72 | The units and other related files have been broken up into the following | |
73 | directories: | |
74 | ||
75 | acl/ | |
76 | This is an old patch to begin to detect and use ACL (access | |
77 | control list) file protection schemes. | |
78 | ||
79 | compline/ | |
80 | These are similar to the standard units, but I have modified them | |
81 | to have a more uniform compile command line, usually using the new | |
82 | Compile.U unit. I have submitted these for inclusion into the | |
83 | regular dist distribution. (The ccflags.U unit is actually | |
84 | perl-specific since it mentions -DDEBUGGING and -DPOSIX_SOURCE, | |
85 | but that's the only place it is perl-specific.) | |
86 | ||
87 | dist_patches/ | |
88 | These are patches to dist that must be applied before it is built | |
89 | and installed. I have submitted these for inclusion in the | |
90 | regular dist distribution. | |
91 | ||
edd6115f JH |
92 | installdirs/ |
93 | These are units to handle perl's installation directories and | |
94 | related issues. | |
95 | ||
959f3c4c JH |
96 | modified/ |
97 | These are modified versions of the standard units. Also included in | |
98 | this directory are new units that are clearly derived from existing | |
99 | units. I have submitted these for inclusion in the regular dist | |
100 | distribution. | |
101 | ||
edd6115f JH |
102 | nullified/ |
103 | These are null units that replace units in the standard | |
104 | distribution. Typically they are there because some part of the | |
105 | perl source accidentally uses a symbol that metaconfig means we | |
106 | want the corresponding unit. | |
107 | ||
959f3c4c JH |
108 | perl/ |
109 | These are specific to perl. Some are heavily derived from | |
110 | original dist units, and are marked as such. Others are original. | |
111 | ||
112 | perl_patches/ | |
113 | These are patches to the perl source. This directory | |
114 | should ordinarily be empty, but there may have been drift between | |
115 | the standard version of perl and the one associated with these | |
116 | units. | |
117 | ||
118 | protos/ | |
119 | These are units modified to use the new Hasproto.U or Protochk.U | |
120 | units to check for prototypes. I have submitted these for inclusion | |
121 | into the regular dist distribution. | |
122 | ||
123 | target/ | |
124 | This is the very, very beginning of cross-compiler support. | |
125 | It doesn't work yet, and many standard units will need | |
126 | modification. | |
127 | ||
128 | typedefs/ | |
129 | These are standard units modified to use the modified Typedef.U | |
130 | unit to check for typedefs. (The modified Typdef.U includes a | |
131 | function to avoid unnecessary prompts if the typdef being searched | |
132 | for exists.) I have submitted these for inclusion into the | |
133 | regular dist distribution. | |
134 | ||
135 | threads/ | |
136 | These are specific to threading perl. | |

160 | Which one to use is your choice. | |
161 | ||
162 | The units in the "modified" directory have been derived from units | |
163 | associated with the metaconfig program of Raphael Manfredi's "dist" | |
164 | distribution. These units list Raphael Manfredi as the Copyright holder. | |
165 | dist is distributed under a modified version of the Perl Artistic License. | |
166 | Clause 7 of this modified license as contained in dist-3.0-pl60 provides: | |

169 | that you explicitly state where you got them from, in the source code | |
170 | (and, left to your courtesy, in the documentation), duplicating | |
171 | all the associated copyright notices and disclaimers. Besides | |
172 | your changes, if any, must be clearly marked as such. Parts reused | |
173 | that way will no longer fall under this license if, and only if, | |
174 | the name of your program(s) have no immediate connection with the | |
175 | name of the Package itself or its associated programs. You may then | |
176 | apply whatever restrictions you wish on the reused parts or choose | |
177 | to place them in the Public Domain--this will apply only within the | |
178 | context of your package. | |
179 | ||
180 | In accordance with this clause, the versions of these units | |
181 | contained here are made available under the same terms as the | |
182 | rest of the units. | |
183 | ||
184 | If you have any questions about the use of these units or about | |
185 | the differences between these units and the standard versions, please | |
186 | feel free to ask. | |
