I am trying to install the visualruby gem on Windows 7 (64 bit, but running 32-bit Ruby 1.9.3 (ruby 1.9.3p448 (2013-06-27) [i386-mingw32]). The last line before failure is: checking for rb_cairo.h... no and then it fails with: *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. I have installed the VisualRuby and all it's prerequisites as described here: http://visualruby.net/site/Download.html, including GTK2 (gtk2 (2.2.4 x86-mingw32)). Do I need to set any of the configuration options? I see cairo.h is located in the following folder: C:\Ruby193\lib\ruby\gems\1.9.1\gems\cairo-1.14.1-x86-mingw32\vendor\local\include\cairo But none of the configuration options seem to specifically address cairo.
