Summary 0004520: mbregex missing from PHP
Description I'm attempting to migrate an application from blastwave stable to recent opencsw and I get the following message:
PHP Fatal error: Call to undefined function mb_ereg_replace

This can be reproduced easily with:
echo '<?php print mb_ereg_replace("a", "b", "lalala\n"); ?>' | /opt/csw/php5/bin/php

According to phpinfo(), php5 was compiled with --enable-mbregex=shared yet I can't find any shared library corresponding to mbregex. Has it perhaps been forgotten in the packaging. I do have mbstring and it is enabled in the configuration file. On the old installation, phpinfo() reports a bare --enable-mbregex.

 *bounce* I am waiting desperately for this issue to be resolved, but there seems to be no progress at all. Is there still hope that someone takes care of this issue?

 Do you have php5_mbstring installed? I think it provides the functions you're missing.

HTH.

 Yep, php5_mbstring is installed, but mbregex is missing nevertheless.

Regarding to http://www.mail-archive.com/maintainers[AT]lists.opencsw.org/msg06843.html [^] (grrr ... replace [AT] by @ to make this link work ... this was needed due to horrible formatting of the URL by Mantis), mbregex is supposed to be in the main package php5, but was somehow left out when packaging it.

Anyways, thanks for your help.

 The most recent test packages still exhibit this problem. mbstring is enabled and it seems mbregex is on by default. I'm still investigating but I likely won't have a fix before the pending release.

 /* #undef HAVE_MBREGEX */

main/php_config.h doesn't define HAVE_MBREGEX, so we don't get that support. I'm now tracing why this doesn't get toggled on...

 Seemingly something with their autoconf is messed up. Even though mbregex is supposed to be on by default, passing --enable-mbregex=shared was seeing it disabled. I've removed this argument to configure and am rebuilding it now.

 A colleague of mine worked around the problem by recompiling the exact same version of PHP to get the mbregex module. He can't remember what he had to do with the configure options but he did somehow get it to build the module. This was a clean build without any of the gar stuff.

 Solved by removing the --enable-mbregex=shared configure option. Testing appreciated: http://buildfarm.opencsw.org/experimental.html#php5 [^]
