Hi! I'm using the ruby interpreter inside a console application written in C. I compile the C code with the freely downloadable version of the Microsoft Compiler (Visual C++ Toolkit 2003) and the Ruby182-15 ( the Windows Installer version). I'm able to interact with the ruby objects using the Ruby C API and use several ruby standard modules. Now, I would like to insert a GUI and use tk or fox. I tried to create a ruby module BUT the application crashes (the interpreter seems to crash) when I put the following instructions in a ruby module: require 'tk' The same happens if I require 'fox12'. The interpreter doesn't emit any error message in the standard output; I expected to have some message because if, for instance, I call a method that is not defined I get a message in the standard output. The same ruby module, if launched by the command line using the ruby.exe program works correctly. Do you have any idea? Thanks Ivan
