Dear RoR Developers,
I have an error when i install RMagick, i have install ImageMagick already but when i use it in gemfile gem install rmagick. i got error.

ERROR:  Error installing rmagick:
        ERROR: Failed to build gem native extension.

after that i do a research and i follow the tutorial i got another error.

It is no good saying that you got another error without telling us what that error is.  Also tell use what operating system you are using.

What do you mean when you say "when i use it in gemfile gem install rmagick".  Exactly what have you put in Gemfile?  Exactly what are you doing to get the error and exactly what is the error?
