Error while installing mahara

[gaurav]

mahara version:- 1.9

OS :- windows 7 (64 bit)

Installation of mahara is taking too much time and lastly it gives following error

Failed to install (check logs for xmldb errors)
Call stack (most recent first):

    install_from_xmldb_file("C:\wamp\www\mahara/lib/db/install.xml") at C:\wamp\www\mahara\lib\upgrade.php:291
    upgrade_core(object(stdClass)) at C:\wamp\www\mahara\admin\upgrade.json.php:78

I got the same Error, trying to install the 1.9 Mahara.
OS is also Windows 7 64-bit, but I´m using the xampp-package

Now I got the Installation runnig by a little work-around.
But I´m not realy sure, what the consequences for Mahara are.

I just deactivated the line 291 in the /lib/upgrade.php

290 if (!empty($upgrade->install)) {
291 //install_from_xmldb_file($location . 'install.xml');
292 }

At first sight this seems to have no visible effect on the functionality of Mahara.

Hi Matthias;

This function is required to install all Mahara tables. Bypass this will cause later problems.

Can you provide the error log?

To expand on what Son, said, the call to install_from_xmldb_file() is what actually creates ALL the tables in the database. If your Mahara installation is still working even after you comment this out, then it probably means that on your first installation attempt, Mahara successfully created the tables before it stalled out. Then on your subsequent attempts to install, it choked because the tables were already present.

Normally it's recommended to delete and recreate the tables and the dataroot between installation attempts, in order to avoid these kinds of problems.
