Darn. I had read the description of start_over--about a month ago, in
the 4.2 docs--but had mentally tagged it with this phrase from the
description: "to recover from irresolvable errors", and didn't think of
it in connection with going to a new version. (I'm not claiming this was
logical.)
Executing scripts/start_over got rid of the
/usr/lib/perl5/site_perl/OSCAR/PackMan.pm from 4.2, that didn't have
either repo() or output_callback().
It also got rid of a number of things I had added manually early on,
to get things going, notably perl-Qt. Section 5.1.1 of the 4.2 docs says:
When installing Linux, it is not necessary to perform a
"custom" install since OSCAR will usually install all
the software on which it depends. ... Typically, a
"Workstation" install yields a sufficient installation
for OSCAR to install successfully.
so I had done a basic (FC5-x86_64) Linux install, with the expectation
that the OSCAR install would take care of all its dependencies.
But when configure is run, no RPMs have yet been installed:
Configuring OSCAR version 5.0a1r4732
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking how to create a ustar tar archive... gnutar
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking for Perl environment... checking for perl... perl
checking for puic... no
configure: WARNING: *** You will not be able to build the OSCAR wizard
configure: WARNING: *** You need to install Perl-Qt to be able to build the
wizard
configure: WARNING: *** Developer checkouts from Subversion *MUST* have puic
configure: error: Cannot continue
(Note: Not having perl-Qt was a problem (albeit non-fatal) even when I
was building from the 4.2 distribution rather than Subversion.)
To be on the safe side, I preinstall perl-XML-Simple and perl-Tk as
well. I haven't checked carefully whether this is actually necessary.
Various other little things had to be fixed. I copied various RPMs
from */distro/rhel4* to */distro/fc5*, but found, for example, that
some rhel4 Python RPMs require python2.3, even when the corresponding
fc5 RPMs require python2.4. In these cases I rebuilt from the source
RPMs. It's not obvious why some of those RPMs require a specific Python
version rather than simply a sufficiently-new version.
By midday Tuesday it seemed that I was down to just one remaining
problem:
--> Running transaction check
--> Processing Dependency: /usr/bin/python2.3 for package: apitest
--> Finished Dependency Resolution
Error: Missing Dependency: /usr/bin/python2.3 is needed by package apitest
Oscar Wizard preparation script failed to complete at ./install_cluster
line 226.
This took from then until this morning to solve. It seems that one of the
files left untouched by the start_over script was
/var/cache/yum/distro_fedora-5-x86_64/headers/apitest-0.2.5+1-4.x86_64.hdr
left over from the 4.2 build.
Removing that file and simply rerunning install_cluster wasn't enough,
so I did:
scripts/start_over
rm -rf /var/cache/yum/distro_fedora-5-x86_64
rm -rf /var/cache/yum/oscar_fc-5-x86_64
rm -rf /tftpboot/distro/fedora-5-x86_64{repodata,repocache}
make clean
make distclean
and then a new build, which worked, in that I now have the OSCAR Wizard
GUI on my screen.
Of course, it may self-destruct as soon as I get brave enough to click
on something other than a Help button, but I wanted to report where I
was at a time when things were looking good.
Following the start over sequence just above, I execute a script I call
file-teardown, to put things back to the way subversion expects them
to be. Then I run svn update (I'm now at 4770) and examine the output
to see whether I need to modify file-setup and file-teardown (e.g. new
x86_64 files available). Then I run file-setup:
#! /bin/sh
#
# The purpose of this script is to set up files required for fc5-x86_64
# It needs to be run ahead of autogen.sh
#
# Ultimately, the required files will simply live in the repository, but
# for now they will be generated, copied from rhel4-x86_64, or obtained
# by whatever method seems good at the time.

#
# The purpose of this script is to remove directories and files set up by
# file-setup, so that--together with make clean and make distclean--a clean
# environment can be restored.

rpm -e perl-Qt perl-XML-Simple perl-Tk
After file-setup, it's straightforward:
./autogen.sh
./configure
rm -rf /opt/oscar/*
make install
cd /opt/oscar
./install_cluster eth0
The last line used to be
OSCAR_VERBOSE=1 ./install_cluster eth0
but I'm hoping not to have to use that any more.
I've made a couple of simplifications above. I mostly do builds as "ted"
and only do the parts I have to as "root", and verbose commands entered
from the keyboard actually go in like this:
(<command>; echo $?) 2>&1 | tee <seq#>.log
which is not too onerous, since they are generally just reentered from
the bash command history.
With regard to scripts/start_over, I suggest putting something at the
beginning of Detailed Cluster Installation Procedure like this:
Unless this is the very first actual or partial OSCAR
install since the installation of the operating system,
you need to consult Section n.nn, Starting over--installing
OSCAR again.
and the script should zap a few more things, as noted above.
Thanks for helping me get this far!
