Description

I just fetched the head of the 1.6 branch and attempted a clean new install. However, instead of getting the installation script's welcome page, I get a blank page and the http logs the following error

[Mon Jan 8 17:08:49 2007] [error] PHP Fatal error: Cannot redeclare xmlize() (previously declared in /Library/WebServer/Documents/moodle/lib/xmlize.php:46) in /Library/WebServer/Documents/moodle16/lib/xmlize.php on line 70

This is most probably a bug in include handling in your PHP. What version are you using?
In anycase I have changed the install.php script in HEAD to use FILE instead of include starting with dot, this might solve it. But I guess you still might run into other problems if the include/require does not work as expected.

I have changed the priority because this bug is not blocker, you can try manual install instead.

closing now.

I am using PHP 5.1.6 and I have Moodle 1.5.4+ running on that computer. It can, of course, be a PHP issue. I am aware of some issues causes by PHP 5.2 but as far as I know 5.1.6 is ok.

What do you mean by manual install, please? I am following the installation procedure given at moodle.org and there is no mention of any alternative. This is my own server not a hosted account. I put the software where it belongs, and go to my moodle's address, which really launches the install.php script (going to install.php directly does exactly the same). That is where I get stuck: I should get the welcome page to begin installation but get an empty page instead. If that is not a blocker, then I don't know what you call a blocker.

I got a private email from someone who seems to have experienced the same problem. He wrote he had happened to fetch the code about a week earlier and it worked, so he just rolled back to that version. If that is true, it can be some fairly recent change that causes the trouble.

I find it ridiculous that you are fixing such an issue in 1.8 development and not in 1.6 branch. This is rather disrespecful for Moodle users who may have a need to install 1.6 anew, like I do. If I experience such a serious trouble, others may too. Even if the development focus is on 1.7 and 1.8, one should be able to install 1.6.

Blocker is a problem that affects significant number of people that results in non-functioning sites or major data loss.

Manual installation means to copy config-dist.php to config.php and manually edit the file to state your server settings.

I am not sure what is causing this problem on your server, but it works on my test servers (and now I know only about two servers affected from your reports) - that is the reason I do not want to commit code I can not test into STABLE release - sorry.

I can only help if you find out more about the problem yourself or find a way to replicate it on another server. You can also try to install the latest version from HEAD. In anycase please add detailed server configuration, thanks.
