Pulling Hair Out - TWiki 4.2 on CentOS 5
 

Are you positive that you have all of the required Perl modules
(and the correct versions)?

Twiki is Perl based, so the PHP on your system should be benign

I thought I would turn here before giving up. I am trying to install Twiki 4.2
on CentOS 5 with all updates. (I also tried Twiki 4.1.2 as well)



I am running a custom rolled Apache 2.2.8 server and custom rolled PHP 5.2.6
(built with oracle support). These work and are rock solid. I've been using the
same config with very heavy duty scripts and php applications with no issues.



When trying to run /twiki/bin/configure I get the following error when clicking
"Next":


Software error:

Use of uninitialized value in substitution (s///) at (eval 25) line 23.





The Apache error log says pretty much the same thing. (like
23 by the way points to a commented line; the first 100 or so lines in this
script are comments.. If I don't count the commented lines there is no search
regexp anywhere near line 23)



I then tried version 4.1.2 and the same thing.



I googled and found numerous other people having this problem. I have found no
responses or solutions. The twiki support site has yielded nothing as well.



Just hoping someone here might have sorted this out.. I have set up dozens of
twiki sites but haven't played with it in a 2 years or so and wondering... It
was never this difficult before.. Three of us have now triple checked every
file permissions, installation step, system pre-requisite, etc...



Thanks for any help,

CC

Yes.. All perl modules, including the optional ones are installed (including clean 'make test's) Yea not sure why I mention the custom PHP version.. Meant to mention the perl version which is 5.8.8.

I have a 4.1.2 version running under Centos 5 without problems but had
some similar issues trying to upgrade to 4.2, mostly in the configure
and module installer routines, not normal operation. I think they have
to do with mixing CPAN and RPMforge perl modules but I haven't
completely pinned it down. Starting fresh, I'd try all EPEL modules for
the perl bits missing in the stock repo. I think that will get you to a
point where the only software error is a 'subroutine install redefined
...' when using the configure part to add plugins.

Hmmm. That might be correct. I've drilled down into the configure script and it pukes here:

print STDERR "MARK 10.1
";
$query = new CGI;* # It dies on this line
print STDERR "MARK 10.2
";


It never gets to MARK 10.2.

I am using the CPAN version of CGI:

cpan[1]> install CGI
CPAN: Storable loaded ok (v2.15)
<SNIP>
Going to write /root/.cpan/Metadata
CGI is up to date (3.37).


cpan[2]>


Grrr... Frustrating... Each time I've tried to use Twiki over the last few years we've ran into some show-stopping roadblock. (always been solaris until now, trying on centos this time)

Many packages require many other sub-modules and the relationships
sometimes change. Either CPAN or the RPM packages will have this
consistent at any particular version, but you can install a newer CPAN
part, then have one of the subcomponents it needs replaced by an older
one that doesn't work in an RPM update - or something like that... If
you pin it down, please let the rest of us know.

1. Did you follow the install instructions? as of:
http://twiki.org/cgi-bin/view/Codev/TWikiOnRedHat

2. Ask on their forums. They are very helpful.

If you have a test box where you can start from scratch, try setting up
yum for the epel repo and install at least this set of modules via yum:


mod_perl
perl-CGI-Carp
perl-Config
perl-Data-Dumper
perl-Error
perl-File-Copy
perl-File-Find
perl-FileHandle
perl-IO-File
perl-Text-Diff
perl-CGI-Cookie
perl-CGI-Session
perl-Digest-base
perl-Digest-SHA1
perl-Jcode
perl-Locale-Maketext
perl-Locale-Maketext-Lexicon
perl-Net-SMTP
perl-Unicode-Map
perl-Unicode-Map8
perl-Unicode-MapUTF8
perl-Unicode-String
perl-URI

And please edit your mails when replying.

...And here is my favorite quote. Jim Perrin explains why CPAN should
be avoided:
