## Here’s what happens when I try to install mongrel\_cluster:

C:\Documents and Settings\root1\>gem install mongrel\_cluster  
Install required dependency mongrel? [Yn]  
Building native extensions. This could take a while…

ERROR: While executing gem … (RuntimeError)  
ERROR: Failed to build gem native extension.  
Gem files will remain installed in  
c:/ruby/lib/ruby/gems/1.8/gems/mongrel-0.3.13  
.4 for inspection.

## Results logged to c:/ruby/lib/ruby/gems/1.8/gems/mongrel-0.3.13.4/ext/http11/gem \_make.out

Before, I had just mongrel installed. Then this happened, and I tried  
uninstalling mongrel first. But, the same thing happens.

Any idea about where to go from here?

Thanks,  
Daniel

Okay, yeah, so basically it’s about having Visual C++ 6.0 (Standard  
Edition works fine) with Service Pack 6 installed. Once that’s done  
(plus the obligatory reboot), extensions compile just fine! 🙂

Yeah… the mongrel\_cluster stuff doesn’t natively work with Windows.

However, if someone would be nice enough to compile it as a win32 gem  
(hint  
hint) that would be great.

It’s most likely not gonna work on Windows. At least that was the last  
official response. But if you can get it compiled… let’s investigate  
it!  
I’m up for it.

Sure thing 🙂 How would I go about doing that, though?

I should note that I could not get the darn thing to work, though…  
I’m at the point where I’ve screwed up the server so bad, we have to  
reinstall Windows… Gonna try with VMware tomorrow to find the right  
approach. I can compile the mongrel\_cluster stuff for you then.

Cheers,  
Daniel
