Plone 4.0.5 unified installer failing on Ubuntu 11.04 (natty) with zip/zlib error

I am a Plone newbie and am trying to install Plone 4.0.5 on Ubuntu 11.04 Natty using the Unified Installer.

I unpack the installer and run the ./install.sh zeo as root and I get the following error:

ZEO Cluster Install selected

See the detailed installation log at /tmp/Plone-4.0.5-UnifiedInstaller/install.log
to determine the cause.

I have installed these ubuntu packages too:

apt-get install zlib1g zlib1g-dev zlibc libghc6-zlib-dev zlibc

The install.log is quite big - I'm just including mentions of zlib here:

To find the necessary bits, look in setup.py in detect_modules() for the module's name.

I can't find a setup.py in the installation files.

Any ideas what I should do or what I should be looking for?

Thank you.

Its an issue with the Python disutils and the new multilib setup of natty. I ran into the same issue trying to get sqlite support in Python built from source.

You can hack around it in the detect modules section of the setup.py

http://bugs.python.org/issue9762

Edit:

To work around it, change lib_dirs in the python setup.py (around line 408) to this (for an x86_64 machine):

lib_dirs = self.compiler.library_dirs + [
    '/lib64', '/usr/lib64',
    '/lib', '/usr/lib', '/usr/lib/x86_64-linux-gnu',
    ]

(the /usr/lib/x86_64-linux-gnu is missing)

Thank you - Plone installed successfully.

Following this and this led me to this patch for setup.py

For sake of other newbies - here is how to apply the patch:

View the raw text of the patch here and copy from the line immediately following (not including) the diff... line to the end. Copy into a text file. For this example let's say you named this file /tmp/patch.txt

Change to the root directory of the unpacked Unified Installer files and then do the following:

cd packages
tar xjf Python-2.6.6.tar.bz2
rm Python-2.6.6.tar.bz2
cd Python-2.6.6
patch < /tmp/patch.txt

If the patch worked you should see:

patching file setup.py
Hunk #1 succeeded at 354 (offset 15 lines).

Then you need to tar and bzip2 the Python package up again:

cd ..
tar cjf Python-2.6.6.tar.bz2 Python-2.6.6
rm -r Python-2.6.6

Now run the installer again and it should be able to find the modules it needs to build the python2.6 included in the Unified Installer.

Instructing the Unified Installer to build its own zlib works: ./install.sh --libz=yes zeo

Note that if you have an acceptable Python on your system already (or can install one), you may use "--with-python=/path/to/Python-2.6" on the install.sh command line.

Works fine for me - but then I built it on a maverick system, then upgraded to natty.

Prereqs that I have that look necessary for you:

zlib1g-dev (which you have)
python-gdbm
libgdbm3
libsqlite3-0 (hard to imagine you would not have that)
python-tk

bsddb & sunaudio are both part of the system python2.6 - you could try building with that (aptitude install python2.6, if necessary)
