Hello list, I'm having a problem getting Gruff working with Rails on a Windows XP box. I installed RMagick, then Gruff via the win32 gem, and it seemed to go OK. From irb, I can do the following - require 'rubygems' ##### This returns 'false', but seems to work OK - require 'gruff' ####### Ditto - g = Gruff::Bar.new etc., and I get a nice PNG file containing my graph Despite the fact that the two 'require' statements are returning false, Gruff still appears accessible. Within Rails, it doesn't seem to work at all. I've tried require 'gruff' and require 'rubygems' require 'gruff' at the top of a controller, but Rails falls over with no such file to load -- gruff whenever I access that controller. It looks like Gruff isn't there, except that it actually works OK from irb (in spite of not appearing to be there!!!). Does anyone have any clue what's going on here? Thanks in advance Dave M.

Nice pickup about needing to - require_gem 'gruff' but it didn't quite fix things. Now I'm getting - Could not find RubyGem gruff (> 0.0.0) from within Rails. However, irb gives a 'true' when I require_gem 'gruff' so it's definitely improved things slightly. I stop/started Webrick but it didn't change things. Thanks anyway. Got any other thoughts? Regards Dave M.

David, What happens in irb when you type require 'RMagick' ?

When I had this problem (on Fedora Core 4) one of the problems was that ImageMagick couldn't find the font it wanted - in my case, it was Arial.ttf. As "De Railed" suggested, what happens when you type "require 'rmagick'" in irb? Yours, tom

require 'RMagick' gives a false as well Not sure what you mean about checking the logs. irb doesn't write verbose logging messages anywhere, does it? Thanks Dave M.

Nah, I was thinking the Apache or Webrick logs... maybe there's some sort of error appearing in there... Yours, Tom

As I said earlier, even though require_gem 'gruff' fails, from within irb I can still create new Gruff objects successfully. Very frustrating... Thanks Dave M.

> Gem::LoadError: Could not find RubyGem rmagick (> 0.0.0) Hm, interesting! Seems like that may be the problem... if you do a "gem list" from the command line, is rmagick in that list? Probably not... do you get error messages when you do a "gem install rmagick"? Yours, Tom

'gem list' includes RMagick-win32 (1.9.2) RMagick is an interface between the Ruby programming language and the ImageMagick and GraphicsMagick image processing libraries. so it looks like it's there OK. I just did another 'gem install rmagick' to see if it made any difference. I forgot this happened before, but this is what I got: Attempting local installation of 'rmagick' Local gem file not found: rmagick*.gem Attempting remote installation of 'rmagick' Updating Gem source index for: http://gems.rubyforge.org Building native extensions. This could take a while... configure:1: Can't exec \bin\sh (fatal) ERROR: While executing gem ... (RuntimeError) ERROR: Failed to build gem native extension. Gem files will remain installed in c:/ruby/lib/ruby/gems/1.8/gems/rmagick-1.10.0 for inspection. ruby configure install rmagick\n Results logged to c:/ruby/lib/ruby/gems/1.8/gems/rmagick-1.10.0/gem_make.out That's why I resorted to downloading RMagick by hand (RMagick-1.9.2-IM-6.2.4-6-win32.zip). This file contained a RMagick-win32-1.9.2-mswin32.gem, which installed without problems. I then ran 'postinstall.rb' as per the README file, and it also ran without problems. It seems to have (sort of) worked, because I can create a .png graph from Gruff under irb; it's just the require... returning a false that seems to be catching me out. Thanks again Dave M.

Ah, that's right, Tim distributes a prebuilt win32 binary, I'd forgotten about that. > It seems to have (sort of) worked, because I can > create a .png graph from Gruff under irb; it's just the require... > returning a false that seems to be catching me out. Hm. I'm flummoxed... if anything else occurs to me, I'll let you know... Yours, tom

OK Thanks Tom for your help to date. I'll update this thread if a solution appears Searching via Google, it seems that a few people have had similar problems with Gruff on Win XP, but no-one's ever posted a fix. Regards Dave M.
