Error: 'simplexml' extension is not loaded

Hi all, I'm really excited to test out projectpier because I've heard so many cool things about it, but when i try to install it I get the following:

* OK: PHP version is 5.2.6
* OK: 'mysql' extension is loaded
* OK: 'gd' extension is loaded
* Error: 'simplexml' extension is not loaded
* OK: /config/config.php is writable
* OK: /public/files is writable
* OK: /cache is writable
* OK: /upload is writable

My fileserver is a Synology DS207, and when i checked their forums it said simplexml was not installed so i installed PHP-apache using ipkg but it still hasn't fixed the issue. Any help would be greatly appreciated!

Cheers

Mick

Can you check these things?

Hi Mick,

the installation script is using the PHP function extension_loaded() (http://us3.php.net/manual/en/function.extension-loaded.php) to check if the required extensions are installed and loaded or not.

One thing you can do is have a basic PHP file like

<?php
if (extension_loaded('simplexml')) {
  echo "Why isn't ProjectPier happy then?";
} else {
  echo "Well, maybe I need to check if it's really installed and enabled...";
}
?>

You need to check that the extension is enabled in php.ini. (some confusing info here: http://us3.php.net/manual/en/ini.php)

You can also check what's enabled with

<?php
print_r(get_loaded_extensions());
?>

or

<?php
phpinfo();
?>

Hi Tim,

Thanks for taking the time to help me out, its really appreciated.

I did what you suggested and here is the output.

1. I ran the getloaded extensions php:
"Well, maybe I need to check if it's really installed and enabled..."

2. I ran the php extension loaded file:

Array ( [0] => xml [1] => tokenizer [2] => session [3] => pcre [4] => SPL [5] => sockets [6] => standard [7] => Reflection [8] => posix [9] => pgsql [10] => mysqli [11] => mysql [12] => mbstring [13] => json [14] => imap [15] => iconv [16] => hash [17] => gettext [18] => gd [19] => ftp [20] => filter [21] => exif [22] => date [23] => curl [24] => ctype [25] => calendar [26] => bcmath [27] => zlib [28] => apache2handler [29] => eAccelerator )

3. I ran the phpinfo file and there was a simplexml comment in there under configuation files

- Configure Command './configure.syno' '--host=powerpc-unknown-linux' '--target=powerpc-unknown-linux' '--build=i686-pc-linux' '--with-apxs2=/usr/local/apache/bin/apxs' '--prefix=/usr/syno/php' '--with-config-file-path=/usr/syno/etc' '--with-pgsql=/usr/syno/pgsql' '--with-mysql=/usr/syno/mysql' '--with-mysqli=/usr/syno/mysql/bin/mysql_config' '--with-iconv=/usr/syno/libiconv' '--enable-mbstring' '--with-gd' '--enable-gd-native-ttf' '--with-zlib-dir=/usr/local/powerpc-linux' '--with-png-dir=/usr/local/powerpc-linux' '--with-jpeg-dir=/usr/local/powerpc-linux' '--enable-exif' '--with-imap=../imap-2004g' '--enable-calendar' '--enable-ftp' '--enable-sockets' '--with-libexpat-dir=/usr/syno' '--disable-dom' '--disable-simplexml' '--disable-libxml' '--disable-xmlreader' '--disable-xmlwriter' '--disable-ipv6' '--disable-pdo' '--without-pdo-sqlite' '--without-sqlite' '--with-curl=/usr/syno' '--disable-cgi' '--enable-bcmath' '--with-gettext'

I think the problem may be that php is still using my old install of apache and not the php-apache service that I installed. Would you know how to change this? Is it in the php.ini file?

Thanks again

Mick
