Redhat Enterprise 5.5 install errors

RT Users

Hi all,

I am trying to install RT 3.8.8 on a RedHat Enterprise 5.5 server. I’ve been able to get most of the dependencies installed except I am running into an XML::RSS dependencies error and an XML::Parser error. Has anyone else run into this issue installing RT on RHEL5 servers? Does anyone have any suggestions?

Thanks,

Jeff

Enter into Perl:
perl -MCPAN -e shell

Have perl recomend updateds:
r

Update the XML::RSS and XML::Parser modules and any others that RT is
using.

It states that all modules are up to date for XML::RSS and XML::Parser. But I am still running into a dependencies fail when I run make fixdeps.

This is the error I’m getting from testdependencies:

cd into:
/root/.cpan/build/XML-Parser-2.36-ak0ybX

I’ve found that I can trace problem’s a little better by trying to do
it manually.
Try running make from there and see if you get anything more meaning
full in terms of error messages.
If make works then try “make test”. That may or may not work. If does
and says something to the effect that is was successful then run “make
install”.

Beyond that I don’t think I help you much more. At least not unless
there are more meaning full error messages at that level.

Hi all,

I am trying to install RT 3.8.8 on a RedHat Enterprise 5.5 server.
I’ve been able to get most of the dependencies installed except I am
running into an XML::RSS dependencies error and an XML::Parser error.
Has anyone else run into this issue installing RT on RHEL5 servers?
Does anyone have any suggestions?

Thanks,

Jeff

Sorry for the delay in replying to this, I have been on medical leave.

IMHO you are much better off using cpanspec instead of CPAN. In
conjunction with a local yum repo it allows you to redeploy, duplicate,
and update your current production system with greater ease. cpanspec is
available in the EPEL repository [1].

The idea is to run cpanspec on your development machine, push the RPMs
in to a local yum repo, then install the RPMs on your server from there.

The downside is that you have to manually build the dependency tree,
which isn’t so big for RT3. Once you have the packages in a local yum
repo updating them is simple.

Couple of gotchas with cpanspec:

1: Sometimes it misses arch specific files, like man1/* or scripts, just
add the files to the %files section in the generated spec file and
rebuild it. rpmbuild will tell you which files are not packaged.

2: To upgrade core modules you need to be a little sneaky, since you
will get file clashes when trying to install the new RPM. This can be
overcome by modifying the spec file.

2A: Modify the build line to use an earlier path.

e.g. ExtUtils::MakeMaker has script, man1, and man3 files that clash, so
lets push those files in to paths used before the core path:

$ cpanspec ExtUtils::MakeMaker

perl-ExtUtils-MakeMaker.spec is the spec file generated by cpanspec

perl-ExtUtils-MakeMaker.spec.noclashes is the spec file edited to avoid
file clashes

$ diff -u perl-ExtUtils-MakeMaker.spec
perl-ExtUtils-MakeMaker.spec.noclashes

The above changes move the perl files from the default path in to the
vendor path, and moves the scripts and man pages in to /usr/local/. All
of these paths come earlier in the search for files, so this effectively
over rides these files without affecting the files shipped by Red Hat.

2B: There are similar options to INSTALLVENDORSCRIPT et.al for
Module::Build based modules. See the “INSTALL PATHS” section in the
Module::Build man page. If you see Build.PL instead of Makefile.PL then
it’s using Module::Build.

2C: If there are clashes with files in the vendor directories, then use
site, it is searched before vendor.

e.g.:

%{__perl} Makefile.PL INSTALLDIRS=site
INSTALLSITEMAN3DIR=/usr/local/share/man/man3
…

I’ve found this approach not only makes maintaining RT3 systems on RHEL
much easier, it also makes sys-admins much less grumpy … which is
always a good thing for ones health and well being! [2]

Hope this helps.

Cheers, Jeff.
