Allan,
Thanks again for describing that "install_cluster" and "wizard_prep" (and
as hinted by you, doubtless further scripts down the road) need to be
"hand-held" regarding how to find the custom perl and python modules.
Remembering about PERL5LIB should've been obvious. (And thanks for
reminding that there should be no quotes around the arg when exporting
PERL5LIB - no worries ;). I'll confess that I haven't yet had to
explicitly export PYTHONLIB, but I haven't gotten that far yet.
Only, (properly) exporting PERL5LIB still doesn'ty fix things.
It's possible I've missed something. You'd think this would (trivially)
work and enable all the install scripts and scripts called therein to
work. To reiterate, the variable is exported from the shell invoking
"install_cluster", with contents determined by "updatedb" and "locate
PackageSmart (or PackagePath, or...)", ie., /opt/oscar/lib/ (leaving out
the trailing OSCAR/, since this is explicitly included in the scripts).
It's easy to test that one is using the right variable contents, by
substituting a bogus value and watching it fail, and to test that
wizard_prep is inheriting the variable (by having it echo it, say). All
seems well here.
Only it isn't helping. What might perplex me is that, in
/opt/oscar/scripts/wizard_prep, the "use OSCAR::PackagePath;" statement
succeeds (and can only succeed when PERL5LIB is set correctly) yet the
call of a subroutine (prepare_pool()) in PackageSmart, further down, fails
with "Undefined subroutine", and moreover, as if it can't find
PackageSmart at all; PackagePath and PackageSmart sit right next to one
another in /opt/oscar/lib/OSCAR. I'm obviously missing something. Again,
the only thing I can think of comes from what happens if one also puts a
"use OSCAR::PackageSmart;" in wizard_prep (which you'd think would be
okay); immediate complaints about no "PackMan".
I think the above
"use OSCAR::PackageSmart;" in wizard_prep
is probably right.
Try a locate PackMan.pm and set its path in PERL5LIB
I am trying to get Fedora Core 10 Working.
With a lot of effort for two days I svnned the whole branch and built some
files for FC10 beta
in fc-10-x86_64 and common_rpms
I got the GUI going and server and oscarimage and everything.
I even got a client to install from the Main Imageserver node but it fails with
an rsync code 5 at the end and goes to busy box.
When I reboot the client it just hangs with a blinking cursor at the top.
If any body can help i think it's the install scripts and systemimager I can
upload the files so far for fc10 beta.
Warning. It is very difficult to install and not for novices.

Should it?
Other than PERL5LIB, was there something else in particular you needed to
ensure before wizard_prep could finish and the install GUI (which I have
yet to see) fire up? Do you have a quick synopsis handy of just what you
had to do to get OSCAR installed on F9? I would be very grateful.
In the meantime, I'll triple-check what I'm doing re: your advice.
It's encouraging that at least you managed to get this process to work!

Hi Christopher,
I have succesfully installed fc9x86_64 on an 6 node intel quad core
cluster.
You can try using updatedb as root and then try locate PackageSmart.pm
to locate the file where wizard_prep crashes saying it cannot find it.
Note installing fc9 is hard and not for novices but not impossible. I
have done it.
For wizard_prep to find the file PackageSmart.pm you have to give it's
path without the OSCAR etc suffix to the perl environment variable.
So my apologies to Munkhzorig Gankhuyag there was an error in that
reply that escaped me then.
My reply was #export PERL5LIB=$PERL5LIB:"/opt/oscar/lib"
IT should have been #export PERL5LIB=$PERL5LIB:/opt/oscar/lib
to see what i say try #echo $PATH and it will tell you the path of the
executables in your .bash_profile directory.
So try #echo $PERL5LIB and see what you get. IT it is empty then just
type #export PERL5LIB=/opt/oscar/lib
All these things can be hard coded but for now try this Also do it
always in the shell you invoke ./install_cluster ...
and if you start another shell or close the shell and reopen the shell
and try ./install_cluster .... type #export PERL5LIB=/opt/oscar/lib
Also do the export of the PERL5LIB environment var before you invoke
./install_cluster ... And you may also have to export to PYTHONPATH
later on if you succed with this.
It's actually simple. Try ./install_cluster ... and every time it fails
because it cannot find a perl module or a python module try #locate and
the filename.pm or .py
and then type export PERL5LIB=$PERL5LIB:/path name that you can cut and
paste from the locate output and export PYTHONPATH=$PYTHONPATH:/path to
python module the oscar setup cannot find.
Also if the #locate filename is large redirect it to a file called test
or something and in another xterm type vi test so you can can see it!
It's difficult but doable
Thanks,
Allan Menezes
note also no spaces in the export.
Try this and see if your problem goes away.
Email the results please
Good luck!

Greetings - my first posting.
The quick synopsis is: "Someone HAS to have installed OSCAR 5.1rc1
successfully on Fedora 9 x86_64 by now - I've read the threads and
tried repeatedly but cannot. Please help". I am not a complete
linux newbie.
Please read on. I've now been at this for several days and have hit
a wall.
I'm building a cluster of 16+1 Intel quad-cores for some in-house HPC
and have chosen OSCAR to provide the infrastructure, on Fedora 9
because we've supported Fedora since its inception, it's familiar,
and Fedora has worked as a distro for (smaller) clusters I've made
(by hand) in the past.
So, on top of a fresh (non-updated) install of Fedora 9 on the master
node, I've been attempting to install what the OSCAR site and
SOURCEFORGE both seem to consider the latest (safe, not a
nightly-build) release, 5.1rc1
I downloaded oscar-repo-fc-9-x86_64-5.1rc1.tar.gz and
oscar-repo-common-rpms-5.1rc1.tar.gz, unpacked them into
/tftpboot/oscar/, provided a copy of my entire Fedora 9 distro DVD in
/tftpboot/distro/fedora-9-x86_64, etc., following the instructions in
http://svn.oscar.openclustergroup.org/trac/oscar/wiki/InstallGuide
At this point this posting will look almost identical to one made on
Aug 31 by Munkhzorig Gankhuyag and discussed/answered by Allan
Menezes et al.
(http://www.mail-archive.com/oscar-users@lists.sourceforge.net/msg07168.html);
"I resolved all errors" (in my case this means, among other things,
adding a "|9" to [fedora*:5|6|7|8:*] in
/opt/oscar/packages/yume/prereq.cfg, or manually install perl-IO-Tty
and perl-AppConfig because this wasn't happening automatically) "but
still can't solve this error:
[...]
=============================================================================
== Running OSCAR wizard_prep script
=============================================================================
--> Bootstrapping OSCAR smart package manager
Undefined subroutine &OSCAR::PackageSmart::prepare_pools called at
./wizard_prep line 185.
eval require PackageSmart returned No such file or directory

Oscar Wizard preparation script failed to complete (cd
/opt/oscar/scripts && ./wizard_prep) at ./install_cluster line 285.
"
That thread ended with "export PERL5LIB properly so attempts by perl
to load local OSCAR modules will work
(ie., "#export PERL5LIB=$PERL5LIB:/opt/oscar/lib/" in the shell
you're working in)
and the thread appeared resolved/closed. Unfortunately, by itself
this advice is a step in the right direction (allows, eg., "use
PackagePath;" in wizard_prep to work) but does not solve the
problem. The best I can determine so far is that PackMan needs to be
in there, too, but isn't provided by what I downloaded. The
distro.url exists so the installer can run off to get things not in
the distro directory.
Rather than continue to burn more time chasing this down, please
enlighten me as to how I can even begin the installation process for
OSCAR 5.1rc1 on Fedora 9. Someone on this list must've done this.
I've even contemplated backing up to Fedora 8 (which seems "more
supported"), though we're on the eve of the release of 10.
Thanks in advance,
Chris
