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
