Abort class-pclzip.php : Missing zlib extensions

[Scott Evans]

upon updating my ubuntu-server to karmic alpha6 I am having trouble with zlib1g package claiming to not be installed when it is!

example 1:
I use WordPress (2.9-rare) and I use a plug-in called Google XML Sitemaps, this uses the zlib1g package for compression but when run it fails to complete stating that "Fatal error: Call to undefined function gzopen() in /var/www/blog/wp-content/plugins/google-sitemap-generator/sitemap-core.php on line 1711"

example 2:
I also use the auto update feature as I'm using the daily builds, I get the following error from zlib1g "Abort class-pclzip.php : Missing zlib extensions"

So as you can see from example 1 "gzopen" is undefined but it's part of the zlib1g package right? and in example 2 it is failing to unzip a file this to is a function of zlib1g as well right?

All functionality of both these plug-ins was working fine with Jaunty! now broken under Karmic :(

I'm also getting the error message "Abort class-pclzip.php : Missing zlib extensions" when I try to install new themes in Wordpress 2.8.4. I'm on Ubuntu Karmic Beta 1.

I don't know if it's a problem with zlib1g or php5-zlib. I seem to be missing zlib.so but don't know where to get it.

Seeing as this seems to be a build/packaging problem (/usr/lib/php5/zlib.so not getting into PHP5 package), shouldn't this be re-filed under PHP?

[Scott Evans (vk7hse)]

I would have thought that is was part of the zlib packaging hence why I
submitted it here in the first place! I would have imagined that PHP5
would have merely made this a dependency of it?

I created a new bug against php5 and referenced this one on it : https://bugs.launchpad.net/ubuntu/+source/zlib/+bug/439407

Excuse me, wrong URL -- here is the correct one : https://bugs.launchpad.net/ubuntu/+source/php5/+bug/451405

Guys,

I'm not sure why the file in Wordpress is, which makes it harder to debug, can you either point out the file using their online SVN repo (http://core.svn.wordpress.org/trunk/) or run the following script yourself:

<?php
var_dump(function_exists("gzopen"));
?>

Then, please link a phpinfo or provide php -m (cli).

Further more, are all you guys on i386 or on amd64 as well? The common issue with all zlib related PHP issues seems to be i386.

Just on a side-note, since the Ubuntu package is build with --enable-zlib it won't show a zlib.so in PHP's extension directory. You should only see .so files, for the extensions you build from other ubuntu packages (or manually from source).

Till,

I'm running the 32-bit (i386) edition of Ubuntu 9.10 Beta (Desktop)

I ran the short var_dump() script you suggested, and it returned "bool(false)"

But php -m returns:

the previous was run on an armel system (arm cortex-a8) running karmic 9.10 beta fully updated

So, the problem doesn't seem to be only limited to i386...

I have this bug too. I updated from Ubuntu 9.04 to Ubuntu 9.10 Beta. All was OK on 9.04, but now with 9.10 I can't unzip a file on my local server. Here are some infos:

The code <?php var_dump(function_exists("gzopen")); ?> displays:
bool(false)
