Please download the zip file that contains both the binary gem and the correct precise ImageMagick version used to create the gem.

From: Guillaume Bloss on 21 Jul 2010 11:50 I tried to install the rmagick_win32.zip but actually it does not works with ruby 1.9.1 ... I will try to compile it to get a working version with ruby1.9.1, but it seems to be a very long work since I have to configure all depending libraries by myself ... and also I cant be sure it will works, but well it's a challenge, I work with windows and hate use old slow version ... I think I can try to download all sources of all required libraries and try to compile it with mingw, following the linux instruction, but under windows. -- Posted via http://www.ruby-forum.com/.

I've never seen that specific error message, but have had success getting it to build. I'm assuming you're using a rubyinstaller build of ruby. If so, install the devkit, then look for instructions on the gem list http://wiki.github.com/oneclick/rubyinstaller/gem-list specifically here are my own: http://betterlogic.com/roger/?p=2186 @Luis Unfortunately the binary gems released by the rmagick team on rubyforge are 1.8.x only, last time I checked. Of course it's been awhile since I checked. GL. -r -- Posted via http://www.ruby-forum.com/.

I believe you can build and link with binaries of ImageMagick as long they provide header and libs needed. By this error: "Invalid drive specification. Unable to get ImageMagick version *** extconf.rb failed *** " It is clear that is trying to look for an ImageMagick executable to get the version, investigate inside extconf.rb to see what is doing. I can't help you more on this since I'm not familiar with ImageMagick build process or internals. Trying to fix gems to compile cleanly is a challenging task.
