Hi All,

Am new so my apologies if I don't know what I'm talking about.

I'm trying to install Silverstripe locally. However, I get the following error:
Building database schema...
Fatal error: Call to undefined method Hierarchy::extradbfields() in C:\Program Files\Apache Group\Apache2\htdocs\silverstripe\sapphire\core\model\DataObjectDecorator.php on line 67

I've tried to refresh numerous times as per the comment above the install progress:
If you receive a fatal error, refresh this page to continue the installation

Unfortunately, this had no effect what-so-ever.

I'm running the following:
PHP Version: 5.0.5
Apache: Apache/2.0.63 (Win32) PHP/5.0.5
MySQl Client API version : 4.1.7

I hope that helps. Thanks in advanced,

What version of SS are you trying to install? trying to use any modules as well? extraDBFields was renamed extraStatics quite a while ago so code shouldn't be calling that

I have this problem too with the latest stable version (2.3.6).
I have no idea how to fix that. Changing extraDBFields to extraStatics some lines above only leads to other errors.

I use PHP Version 5.0.5 too. Maybe this has something to do with that fact?
I also tried Version 2.3.5, this did fail too.

With version 2.3.1 I got follwing error:
# Building database schema...

Parse error: parse error, unexpected T_ARRAY, expecting '&' or T_VARIABLE in /xxx/httpdocs/sapphire/security/Member.php on line 982

I think this may be an incompatibility issue with some of the code in Member.php (the array type hint) for the arguments to a method that don't work in PHP 5.0.5.

EDIT: I found some information here that indicates array typing wasn't introduced until PHP 5.1: hence why it won't work.
