I have a file rmg.rb:
require ''RMagick''
include Magick
cat = ImageList.new("prod.jpg")
cat.display
exit
The file prod.jpg is in the same directory as this file above.
I execute the following:
ruby rmg.rb
I get the following output:
/usr/lib/ruby/1.8/RMagick.rb:1377:in `read'': unable to open image
`'': No
such file or directory: (Magick::ImageMagickError)
from /usr/lib/ruby/1.8/RMagick.rb:1377:in `initialize''
from /usr/lib/ruby/1.8/RMagick.rb:1376:in `initialize''
from rmg.rb:4
Any ideas as to what I am missing?
-Thanks.

I installed imagemagick, libmagick-ruby, libmagick-ruby1.8. I tried to run the above rmg.rb in this environment and got the exception. Do I have to do a - gem install rmagick? <--- When I try doing this I get a trace like such: configure: WARNING: you should use --build, --host, --target configure: WARNING: you should use --build, --host, --target Configuring RMagick 1.10.1 checking for install-gcc... no checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking for ruby... /usr/bin/ruby checking for Magick-config... no checking for GraphicsMagick-config... no configure: error: Can''t install RMagick.

Can''t find Magick-config or> GraphicsMagick-config program.The last I heard the RMagick package on Ubuntu was broken in a way that produces exactly the "unable to open image `''" symptom you described. Norman Timmler blogs about how to get around that problem here: http://blog.inlet-media.de/rmagick-does-not-play-well-on-ubuntu When the RMagick install reports that it can''t find Magick-config or GraphicsMagick-config that usually means that you need to install the ImageMagick "development" package that contains the library header files. This must be the libmagick6-dev package that Mr. Timmler mentions. You can always install ImageMagick from source. Here''s the RMagick install FAQ: http://rmagick.rubyforge.org/install-faq.html. I''d really like to help you get up and running. If you can''t make any progress drop me a line at rmagick@rubyforge.org. -- Posted via http://www.ruby-forum.com/.

If you don''t need support for WMF that''s okay. Glad you''re up and running! -- Posted via http://www.ruby-forum.com/.
