Do you get header not found errors when installing a Ruby Gem? (In my case, it's the FastCGI bindings.)
The problem looks something like this:
~/rubygems-0.8.11 >>> mars >>> ~/bin/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 /home2/mars/lib/ruby/gems/1.8/gems/fcgi-0.8.6.1 for inspection. ruby extconf.rb install fcgi\nchecking for fcgiapp.h... no checking for fastcgi/fcgiapp.h... no
This error is because the header [*.h] files are:
Not installed; If "fcgiapp.h" is the problem, make sure you've installed the FastCGI Dev kit.
In a non-standard location; the Ruby Gem configuration script "extconf.rb" doesn't search in Ruby's originally compiled include directory (the directory that was specified using the "--includedir" option when Ruby was built.)
Instead, ya gotta get all specific using the CONFIGURE_ARGS environment variable:
In c shell [tcsh]:
setenv CONFIGURE_ARGS "with-fcgi-include=/path/to/include"
In sh [bash]:
Make sure to replace the 'fcgi' in that value with your problematic Gem's name & '/path/to/include' with the path to your special include directory.
Then, try your "gem install" again!
