RMagick freezes ruby processes when required on OS X Snow Leopard

I've got quite a strange problem. I've installed ImageMagick via homebrew.

I've installed rmagick-2.12.2 and rmagick-2.11.2 with no issues.

I get no errors on installation of either.

ImageMagick seems to be installed and in my path:

$ convert --version
Version: ImageMagick 6.5.6-5 2010-01-30 Q16 OpenMP http://www.imagemagick.org
Copyright: Copyright (C) 1999-2009 ImageMagick Studio LLC

However, as soon as RMagick is loaded or required in a rails application, irb, ruby script, etc. the ruby process competely hangs and can only be kill via kill -9.

I'm not sure how to debug what the issue is here since there is never an error message or stacktrace. Does anyone have any suggestions?

Solution

  • RMagick and Ruby 1.8.6 are no longer compatible on Snow Leopard because of an obscure bug in Ruby that hasn't be backported yet.

    To use RMagick and Ruby on Snow Leopard, make sure you're using Ruby 1.8.7 or above.
