I’ve finally managed to install ImageMagick and build the RMagick gem and make it all work. Hooray. It seems like the problem was in the DLL itself. When I tried to registed it, windows gave me a nice error about a problem with the dll. So my way of solving all the issues is: Go … Read more
I tried your solution (full of hope) but It did not work for me unfortunately. Finally I managed to make it work by reinstalling imagemagick without openmp support (this is the library responsible for lgomp) using Homebrew: brew install imagemagick –disable-openmp then rmagick installed without any problems.
Install the packages imagemagick and libmagickwand-dev (or libmagick9-dev). You should then be able to install the Rmagick Gem. sudo apt-get install imagemagick libmagickwand-dev If not, you are missing ruby related development packages like build-essential and ruby1.8-dev. If that’s the case, a generic “ubuntu install ruby 1.8” query in google should sort you out.

(I’m not sure if thats what he’s actually saying or if he’s saying remove the flag, but the above homebrew command works for me on OSX 10.6) If you already have imagemagick … Read more
If you’re on Ubuntu, installing this package is what fixed it for me: sudo apt-get install libmagickwand-dev
Well I got this working using fog instead or carrierwave_direct. Below is the code that ended up working for me: app/uploaders/image_uploader.rb class ImageUploader < CarrierWave::Uploader::Base include CarrierWave::MiniMagick include Sprockets::Helpers::RailsHelper include Sprockets::Helpers::IsolatedHelper storage :fog # Override the directory where uploaded files will be stored. # This is a sensible default for uploaders that are meant to … Read more
When building native Ruby gems, sometimes you’ll get an error containing “ruby extconf.rb”. This is often caused by missing development libraries for the gem you’re installing, or even Ruby itself. Do you have apt installed on your machine? If not, I’d recommend installing it, because it’s a quick and easy way to get a lot … Read more
