I still have a similar error:

1>.\main.cpp(45) : error C2664: 'rb_define_module_function' : cannot
convert parameter 3 from 'VALUE (__cdecl *)
(VALUE,VALUE,VALUE,VALUE,VALUE)' to 'VALUE (__cdecl *)(...)'
1>        None of the functions with this name in scope match the
target type

Line 45 is the

rb_define_module_function(cTest, "Send", Send, 4);
