Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:
1. Is this reproducible?
2. If so, what specific steps should we take to recreate this bug? Be as detailed as possible.
This will help us to find and resolve the problem.

1. Is this reproducible? -> yes. I use i386 binaries via "jp.archive.ubuntu.com".
2. I always do dist-upgrade with wajig. I can reproduce the bug with extracted php5 command in cached deb files.

Installing the packages the normal way, I cannot reproduce this error at all.

The error also occurs when use package php5-5.2.10.dfsg.1(5.2.10.dfsg.1-2ubuntu4) rebuilded in my machine.

But, it changes well when uncomment the line:

#019-z_off_t_as_long.patch

to

019-z_off_t_as_long.patch

in "debian/patches/series" before dpkg-buildpackage.

I can reproduce this bug.

php -v

cat t.php

php t.php

Fatal error: Call to undefined function gzopen()

From package description:
The following extensions are built in: ... zlib.

uname :
2.6.31-11-generic #38-Ubuntu SMP Fri Oct 2 11:55:55 UTC 2009 i686 GNU/Linux

[bellbind (bellbind)]

Same error is occured at 5.2.10.dfsg.1-2ubuntu5 .

[bellbind (bellbind)]

The bug is NOT zlib link problem because it can open gz files with "fopen" for example:

<?php
$gzfile = fopen("compress.zlib://hello.txt.gz", "w");
fwrite($gzfile, "hello world!");
fclose($gzfile);
?>

is work well on released binaries. BUT "gzopen" is not defined in php5 binaries it cannot run:

<?php
$data = "Hello World!";
$gzfile = gzopen("hello.txt.gz", "w9");
gzwrite($gzfile, $data);
gzclose($gzfile);
?>

[bellbind (bellbind)]

The uncomment patch "019-z_off_t_as_long.patch" changes the situation in my environment build.

The patch only adds header files to php5 sources: "ext/zlib/zconf.h" and "ext/zlib/zlib.h"
But in my env, it also exists "/usr/include/zconf.h" and "/usr/include/zlib.h" by standard package "zlib1g-dev".

I don't know why the existence of the header files changes the build condition...

[Rajoy (siberia-accanto)]

Happens for me too, Ubuntu 9.10, 5.2.10.dfsg.1-2ubuntu5.

[Andreas Otto (andreas-otto)]

Happens for me as well with Ubuntu 9.10, 5.2.10.dfsg.1-2ubuntu6.

hi. I'm using Magento (most used eCommerce framework in the world...)
Magento does not work with PHP 5.3 (as many CMS and frameworks).

So, as many people, I needed to downgrade to PHP 5.2.10 with the very popular trick :
http://dustyreagan.com/downgrade-php-5-3-to-5-2/comment-page-1/

But now, I have the gzopen bug.
I'm a webdevelopper, not a sysadmin. I use Ubuntu because it suppose to be 'easy to use'. I felt yet difficult and weird the downgrading of PHP.

Now, what I'm suppose to do for Ubuntu being able to run Magento ?
Could you please explain in a 'step by step way' how to fix this bug ?

thanks.
