Hi all

I’m trying to follow this guide:

[http://wiki.rubyonrails.org/rails/pages/RailsOnSUSE](http://wiki.rubyonrails.org/rails/pages/RailsOnSUSE)

And I’m having problem with installing fcgi using gems (I’m logged in as  
root):

koelsch:/home/josh # gem install fcgi  
Attempting local installation of ‘fcgi’  
Local gem file not found: fcgi\*.gem  
Attempting remote installation of ‘fcgi’  
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  
/usr/lib/ruby/gems/1.8/gems/fcgi-0.8.7 for inspection.  
ruby extconf.rb install fcgi\nchecking for fcgiapp.h… no  
checking for fastcgi/fcgiapp.h… no

Results logged to  
/usr/lib/ruby/gems/1.8/gems/fcgi-0.8.7/ext/fcgi/gem\_make.out

In addition I wasn’t able yet to install apache2-mod\_fastcgi, but I  
don’t think this is responsible for this behavior?

Thanks for help.  
Josh

It’s trying to link against the C fastcgi development kit. You can  
download  
this from [http://www.fastcgi.com/#TheDevKit](http://www.fastcgi.com/#TheDevKit) and build it (or else your  
base  
system may have this available as a pre-built binary)

I believe the ruby fcgi package does include a pure-ruby implementation,  
which it’s supposed to use as a fallback, but I suspect the gem  
packaging  
hasn’t allowed for this.

No it’s unrelated. I recommend you use apache2-mod\_fcgid though anyway;  
this  
is a drop-in replacement for mod\_fastcgi which is actually being  
maintained.
