Trying to install rails/fcgi/apache2. Following these instructions: [http://xmlareas.com/ruby-rails-howto.html](http://xmlareas.com/ruby-rails-howto.html) Using Fedora Core 4. I installed ruby and ruby-devel using apt-get. Everything under Adding FastCGI (optional) works fine up to the gem install fcgi part. Here is what happens: [root@paulbarry fcgi-2.4.0]# gem install fcgi -r – -with-fcgi-lib=/usr/local/fcgi/lib –with-fcgi-include=/usr/local/fcgi/include Attempting remote installation of ‘fcgi’ Building native extensions.

Did you install the fast CGI development libraries? If so, what path are they located in? Is this path in your LD\_LIBRARY\_PATH, or in your /etc/ld.so.conf file? If you added the appropriate path to your ld.so.conffile, did you run ldconfig afterwards? -Will ---

I couldn’t get the fcgi to work unless I gave /tmp/fcgi\_ipc AND /tmp/fcgi\_ipc/dynamic 777.
