- dist-3.0at70:
- dist-3.0 at patchlevel 70. This is the final version released
- by Raphael Manfredi. Don't use it. Instead, use ...
- dist-3.0at70b:
- dist-3.0 at patchlevel 70 with unofficial patches 'a' and 'b'
- applied. This version was never officially released, but
- the patches are essential, so this is the version we use for
- perl. Actually, I've also applied U/dist_patches/dist-p70c
- to this tree. If someone with commit power wants to change
- the name of the directory, that'd be fine. Otherwise, it
- really doesn't matter.
dist-3.5-20:
dist-3.5-20 is almost meta-4.0, still maintained by Raphael
Manfredi, but with a lot of fixes over 3.0, some changes
- from the perl modifications merged and a much better metalint

+ dist-svn:

dist:
a symlink to the lib you actually use. For Merijn that is
metaconfig/dist -> ../lib/dist
in your $PATH.
The dist version used for perl is dist-3.5-20 in this directory, which is
a slightly modified version of the original, which you can get at the SVN
- repository https://dist.svn.sourceforge.net/svnroot/dist/trunk
+ repository https://svn.code.sf.net/p/dist/code/trunk/dist. If you'd like
+ to keep up to date with changes in dist, you can either use svn or git to
+ create your own clone. For git, that would be something like:
+
+ $ git svn clone \
+ svn://svn.code.sf.net/p/dist/code/trunk/dist \
+ dist-svn
+
Unsurprisingly 'dist' uses (its) Configure to generate itself:
- cd dist-3.5-20
- chmod -R +w . # We have derived files in git :-(
- ./Configure
- make
- make install
+ $ cd dist-3.5-20 # or dist-svn
+ $ chmod -R +w . # We have derived files in git :-(
+ $ ./Configure
+ $ make
+ $ make install
After make install, remove lib/U/d_debugging.U in your target lib, as perl
- uses it's own way to set/define debugging (see INSTALL)
+ uses its own way to set/define debugging (see INSTALL)
the dist-3.5-20 installation as used by Merijn is available on his CPAN as
perl-meta-3.5-20.tgz
We have not yet arranged for metaconfig to use perl's versions of the
'units' by default so you need some housekeeping in the perl directory...
+(aa) -- optional --
+
+ If you plan to make changes to metaconfig or metalint locally (and you
+ probably want to, as both are written for perl4), consider installing
+ mconfig and mlint from the cmon subdirectory into your $PATH too. These
+ are the non-autoloading versions and can easily be changed. Here is what
+ I added at the beginning of mconfig:
+
+ --8<---
+ BEGIN { $ENV{LC_ALL} = "C"; }
+ chdir "/pro/3gl/CPAN/perl";
+ { my @Cc = qw( Configure config_h.SH );
+ system "chown merijn @Cc";
+ chmod 0775, @Cc;
+ #-d "merijn" or mkdir "merijn";
+ #system "cp -f Configure config_h.SH Porting/Glossary Porting/config.sh merijn/";
+ system "ls", "-l", @Cc;
+ }
+ -->8---
+
+ I also added the first two lines of that patch to mlint
+
(b) You need to be in a/the Perl directory, i.e. either something from
//depot/perl/... or one of its branches
(e.g. Nick I-S is usually in //depot/perlio/...)
the best appropriate subdir of U. See U/README for a description of
the various subdirectories.)

You can skip this phase, it's not essential, just good housekeeping.
