7 These units are the ones I used to build Configure and config_h.SH
8 in the Perl5 distribution.
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>.
20 1. Unpack the full perl5 sources. Execute the following command
22 chmod +w Configure config_h.SH Porting/Glossary Porting/config*
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.
30 3. Apply any patches to perl in the U/perl_patches directory.
31 (This may well be empty.)
33 4a. Obtain dist-3.0pl70.
35 4b. Apply any patches to dist under the U/dist_patches subdirectory.
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.
44 6. From your main perl5 source directory, run
48 7. Edit U/mkglossary to point to your dist-3.0pl70 location
49 (See comments at the top.)
51 8. Run the U/mksample script to update the contents of the Porting/
54 9. Let me know about any changes, corrections, or enhancements.
56 Things to watch out for:
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
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.
72 The units and other related files have been broken up into the following
76 This is an old patch to begin to detect and use ACL (access
77 control list) file protection schemes.
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.)
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.
93 These are units to handle perl's installation directories and
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
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.
109 These are specific to perl. Some are heavily derived from
110 original dist units, and are marked as such. Others are original.
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
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.
124 This is the very, very beginning of cross-compiler support.
125 It doesn't work yet, and many standard units will need
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.
136 These are specific to threading perl.
