Boost Python enum_ max value issues

Question

enum MyEnum
{
    SOME_NAME = 2147483648;
};

...

enum_<MyEnum>("MyEnum")
    .value("SOME_NAME", SOME_NAME)
;

While this compile fine, it crashes on initialization cause enum_ is casting values as "long" which is limited to 2147483647. I'd need them to be unsigned long. Is there any way to do that without having to create an entire enum wrapper?

Thanks!

C++ allows you to implicitly cast an enum to an int, not an unsigned int. You're capped to INT_MAX as the maximum value. Furthermore, you have to cast an int (or an unsigned int that becomes sign-converted) to convert it back to an enum.
