Unzipped Expression 1.1 on server
set permissions, made mysql db
Run install, get this

install.php
Fatal error: Cannot instantiate non-existent class: db
in /home/steve/www/expression/install.php on line 507

error_log
/usr/libexec/ld-elf.so.1: /usr/local/lib/php/extensions/current/mysql.so:
Undefined symbol “_safe_emalloc”

The first error might be because the permissions for the /system/db/db.mysql.php file are incorrect OR the file may not exist.  I would check that first.

The second error is not EE related and there seems to be a problem with the MySQL extension/library for your copy of PHP.  You might want to contact your host.

>> /system/db/db.mysql.php file are incorrect <<

What should it be?

Try 644 or 755 permissions.  If it still is having this problem send me an email referencing this thread and I can take a look at your server (and the install script) and see why it is failing at that point.

Used 644 - works fine.  Thanks

I get the same error.  I think it has something to do with my connection to MySQL.  I am running everything from my own PC using Windows with IIS.  So, I don’t have any chmod commands to change permissions as you suggest.

I get teh following error during the ExpressionEngine install….
Notice: Use of undefined constant MYSQL_ASSOC - assumed ‘MYSQL_ASSOC’ in install.php on line 507

I checked the /system/db/db.mysql.php file to see what you guys were talking about and all it does is suggest I install ZendOptimizer so I went ahead and did that.

I am new to MySQL first install.  I have always used MSSQL.  But, I installed MySQL on the same machine and it seems to be working just fine.  I created a passoword for root and connect via the command prompt.

Now I am trying to configure ExpresionEngine because I assume I need it before configuring pMachine.  Because, when I went to install.php pMachine a lot of the pages would not even come up in the install script.  I could manually jump to each page and find some did have content though.  In the ExpressionEngine install.php script I can’t get the “Click here to install” button to work.  I get the line 507 error.

Database Settings
SQL Server Address
(usually ‘localhost’)  (localhost)
SQL Username       (root)
SQL Password       (mypassword)
SQL Database       (mysql)

running….
ZendOptimizer 5.2-Windows-i386
PHP 5.0.1
ActivePerl 5.8
MySQL 4.0
ODBC 3.51
IIS 5.1

oh and I just copied the folder contents in the zip file for ExpressionEngine 14 day trial into my Inetpub/wwwroot/mywebpage folder.  So I can access the install.php from IE using http:/localhost:8080/mywebpage/install.php

Any more info you need let me know, I tried to be thorough.   Any help would be much appreciated.

My guess is that while you have both PHP and MySQL installed, that PHP is not actually configured to use/connect with MySQL.

Here’s a very quick Google search that might help you out.

I thought I already had IIS all set up because I already run a PHP like forum on my web server which works with MSSQL.

Here is a simple PHP test script to connect to MySQL database…

...and when this gave an error not even the Could not Connect message I knew I had something wrong.  So I started checking into IIS setup with PHP.
I found this webpage….
http://www.phpbuddy.com/sub_articles.php?other_articles=4

Now although I already had PHP extension I had it configured to use php-cgi.exe and not php.exe   Once I changed the extension to work with php.exe and retested my simple test.php script I got the Connected successfully message.

Now I get passed my line 507 error but I still get this page saying Zend Optimizer not installed even though I thought I already did install it.

Well any rate I went on to install.php in the pm folder and installed pMachine and it is working now, thanks….
