I try to install passenger on win XP sp3  
I have installed

- ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]
- gem version 1.3.1  
without problems.

I don’t have a web server installed yet, and no database.  
I don’t have any microsoft compiler on my machine, and it looks as  
though passenger requires it (?)  
What am I doing wrong?

## Thanks, Amir

This is what I get:

C:\>gem install passenger  
Building native extensions. This could take a while…  
ERROR: Error installing passenger:  
ERROR: Failed to build gem native extension.

C:/Ruby/bin/ruby.exe extconf.rb install passenger

From the docs (  
[http://www.modrails.com/documentation/Users%20guide.html#\_supported\_operating\_systems](http://www.modrails.com/documentation/Users%20guide.html#_supported_operating_systems)  
)  
“Phusion Passenger works on any POSIX-compliant operating system. In  
other words: practically any operating system on earth, except  
Microsoft Windows.”

More generally if you see “Building native extension…” then you  
either need the appropriate compiler and toolchain or you need to find  
a prebuilt version.
