Status changed to 'Confirmed' because the bug affects multiple users.

Confirming bug on "armv7l" port.

Any workarounds?

[Omar Chris Eugene (xriseugene)]

none that I know of

This doesn't helps (actually the mentioned patch seems to be already applied to the Ubuntu files):
http://cweiske.de/tagebuch/pear-php-5.5.htm

This workaround seems to work for me (still playing around with it). It probably also works for "pear install".
========
# First run pear to download the packages. It will probably put the packages into
# /build/buildd/php5-5.5.9+dfsg/pear-build-download/
# but it can't install them.
$ pear upgrade

# Un-Gzip the downloaded packages.
$ gunzip /build/buildd/php5-5.5.9+dfsg/pear-build-download/*.tar

# Now pear should be able to work with the pure tar-files.
$ pear upgrade /build/buildd/php5-5.5.9+dfsg/pear-build-download/*.tar
========

So by this workaround I guess, the bug's reason is something about the gzip compression.

Hello,

  Can any one please help me. When this bug is going to solve ?

[kolAflash (colaflash)]

@dreamer-panchal
Did you try the workaround I suggested? Did it work?

[Riccardo Mollo (riccardo-mollo)]

Thanks kolAflash, your workaround works great. :D

[Hugo Vieira (hmmvieira)]

I stumbled on this problem today after a fresh install of Xubuntu 14.04 32 bit.
For some reason, kolAflash's workaround is not working for me...

My investigation led me to /usr/share/php/Archive/Tar.php. This script was unable to open tgz files because line 733 was returning "false" when checking for the existence of function gzopen.

With this information, Google showed me a 5 year old bug (still open) that may be related: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/451405

I really really had to install some pear packages, so my solution was to replace the following in Tar.php:
- Lines 733 and 744 - Replace gzopen with gzopen64
- Line 888: Replace gzseek with gzseek64 and gztell with gztell64

This is not a solution but it may help find the solution (or maybe fix the 5 year old's bug?).

Thanks Hugo, that works for me

The workaround on #5 (by kolAflash) worked for me. I think that it is more safe/stable than the solution on #9, which modifies the code. I do it like this (on a script):

----8<----
pecl install uploadprogress
gunzip /build/buildd/php5-*/pear-build-download/uploadprogress-*
pear upgrade /build/buildd/php5-*/pear-build-download/uploadprogress-*

pear channel-discover pear.drush.org
pear install pear.drush.org/drush-6.2.0.0
gunzip /build/buildd/php5-*/pear-build-download/drush-*
pear upgrade /build/buildd/php5-*/pear-build-download/drush-*
---->8----

Hugo's workaround worked for me. I just registered to say thank you ! You're a genius :D

[Dave Mausner (ak-dave-j0)]

If the build problem is too hard to solve, the gross solution is to modify the PEAR file Tar.php so that each reference to compression type 'gz' also tests for the build's function, like this:

        if ($this->_compress_type == 'gz' && function_exists('gzopen'))
            $this->_file = @gzopen($this->_tarname, "wb9");
        else if ($this->_compress_type == 'gz' && function_exists('gzopen64'))
            $this->_file = @gzopen64($this->_tarname, "wb9");

[Chingachkuk (win32-ya)]

Here is the code that helped me getting it working. I injected it to /usr/share/php/Archive/Tar.php.
<code>
/**
 * Missing zlib functions.
 */
function gzopen($filename, $mode, $use_include_path = 0) {
  return gzopen64($filename, $mode, $use_include_path);
};
function gzseek($zp, $offset, $whence = SEEK_SET) {
  return gzseek64($zp, $offset, $whence);
}
function gztell($zp) {
  return gztell64($zp);
}
</code>

workaround from kolAflash (colaflash) worked for me on a raspberrypi2 with ubuntu 14.04 installed, thanks.

some changes:
files are located in /build/php5-0LI9sl/php5-5.5.9+dfsg/pear-build-download/
original downloads have the ending *.tgz

Hugo Vieira (hmmvieira) #9 worked like a charm!

Thanks man, you really helped! :)
