  • in the package, file stdafx.h, line 54:
    #include "C:/ruby/source/ruby-1.8.2/ruby.h"
    needs to be changed to the correct Ruby version source dir
  • This example is quite old, and was written for MSVC 6. If you will be including ruby.h, to compile with MSVC 2005 or higher, you need to comment out the (usually first 3) lines in your Ruby install's config.h file:
    #if _MSC_VER != 1200
    #error MSC version unmatch
    #endif
    The config.h file is located usually in directory:
    C:/Ruby186/lib/ruby/1.8/i386-mswin32
