Installing Drupal

Hi, I'm trying to install drupal but keep running across this error:

unable to select database

I'm running the following configuration:

Operating system Linux
Apache version 1.3.29 (Unix)
PHP version 4.3.3
MySQL version 4.0.18-standard

Can someone tell me what I'm doing wrong?

Thanks for your help.

when I try to get my first user(administrator) account I get the following error:
how to fix it?
also is there any way to set passwords without using email?

Fatal error: Call to undefined function: mail() in /home/skopel/public_html/drupal/modules/user.module on line 237

thanks

I get the following error in my browser when running the latest drupal...

having previously used ASP, i have IIS installed in Windows XP.

i have installed mySQL and myODBC - which as far as i can tell work.

i tried installing Apache, but it conflicted with the http://localhost/ address - which currently defaults to ASP.

how am i going to test drupal on my PC - before uploading it to the web?

can i test it in IIS and then change it to run under Apache?

i put drupal into a virtual directory c:/drupal1
which has an alias of drupal.

Just did a fresh install of 4.4.0, running php5.0rc1. Everything seems to work except that I get the following:

I wanted a menu item that pointed to the general image gallery (?q=image). It looks like there is code in the image_link function to put a link on the menu bar, but i don't get a link that says 'image gallery' there, no matter who i log in as. am i missing something?
