RE: Zend Free Edition under Ubuntu and Segmentation Fault

I've just had a look at the Zend supported platforms for Zend Core, Ubuntu (all flavours) is not mentioned.

FreeBSD isn't a supported platform wither I'm afraid.

Officially, on the Linux front, Only SLES 9 & 10 and Red Hat Enterprise 4 & 5 are supported. I presume that means the Oracle Unbreakable Linux and CENTOS are also "supported" in as much as they are Red Hat clones.

Unofficially, there are a few hits on the support documents for Zend Core when looking for ubuntu.

And also, three hits for Zend Core and segfault:

This does tend to implicate that the latest Ubuntu is incompatible in some way. :-(

Maybe, how did you specify your oci_connect() parameters. I have had extreme difficulty getting any connections to work unless I use:

$c = oci_connect($username, $password, $host . ":" . $port . "/" . $databaseSID);

Try as I may, I cannot get tns aliases to resolve, phpinfo() shows that I have all the environment variables and paths set that I need but no connections at all. Try the above, it might work.

I don't suppose you can find out what line 10 is trying to do? It might be a file that is missing, a library that is no longer there libname.so.6 being found when libname.so.5 is looked for - I often find that a quick "ln -s" helps out in these situations. (Not on production of course!)

The Oracle Underground PHP manual and the Oracle 2 day PHP course (pdfs) both miss out the installing of PHP from source. They both use Zend.

There is a book from Oracle Press, Oracle 10g Express Edition PHP Web Programming by Michael McLaughlin which covers both Zend and installing PHP from source. Pages 16-22. Which basically states:

• Download and unzip php.
• ./configure -with-apxs2=/where/to/find/apache2/bin/apxs
• make
• su
• make install
• Add LoadModule php5_module modules/libphp5.so to httpd.conf.
• AddType application/x-httpd-php .php .phps .phtml to httpd.conf.
• Add PHPIniDir "/etc" to httpd.conf.
• Restart Apache.

HTH Cheers,
