RMagick RVM installation failed

I keep getting this error when I'm installing rmagick inside rvm.

checking for InitializeMagick() in -lMagickCore... no
checking for InitializeMagick() in -lMagick... no
checking for InitializeMagick() in -lMagick++... no
Can't install RMagick 2.13.1. Can't find the ImageMagick library or one of the dependent libraries. Check the mkmf.log file for more detailed information.

Here's my current setup:

Snow Leopard 10.6.7
XCode 3.2.6
RVM 1.6.1
Ruby Over RVM (ree1.8.7)
Homebrew 0.8
ImageMagick 6.6.9-4 c/o Homebrew

After installing imagemagick with Homebrew, I was 开发者_JAVA技巧able to install rmagick using the system ruby

rvm system
sudo gem install rmagick

Any ideas?

I think that there was a problem with the imagemagick package from homebrew for a small period of time. I just walked through re-installing rmagick on my system (also 10.6.7 with RVM). First I re-installed imagick:

brew uninstall imagick

and then

brew install imagick

Finally I did

gem install rmagick

Which compiled with no problems. I can't see why it would cause you problems but you don't need to use sudo when use rvm unless you installed RVM as root.

RMagick expects for Homebrew to provide certain symlinks which don't exit, causing a whole lotta problems.

You can run this gist to create the symlinks specific to your ImageMagick installation that are needed for RMagick to work.
