I stuck in search element problem. I am trying to install ferret on my  
window 7. But tried a lot but couldn’t succeed.

I ran following command to install the ferret gem.

gem install ferret  
gem install ferret --version (all versions)  
gem install ferret -v 0.11.5  
gem install ferret -v 0.11.6  
gem install ferret -v 0.11.8.4  
gem install ferret -v=0.11.6 --platform mswin32

I also changed the devkit, got a updated kit and change requisite path  
in fstub

But couldn’t succeed. Always it gives me following error  
ERROR: Error installing ferret:  
ERROR: Failed to build gem native extension.

```
    c:/RailsInstaller/Ruby1.9.2/bin/ruby.exe extconf.rb

```

creating Makefile

make  
c:/RailsInstaller/Ruby1.9.2/bin/ruby -e “puts ‘EXPORTS’,  
‘Init\_ferret\_ext’” \> f

Please help me.

Any help or suggestion is appreciable.

Thanks
