digitalmars.D.learn - GtkD compile failed. shift by 32

Just browsing through the source it looks like gtkColor.red is a ushort.
I get this error.

I get that exact same message no matter which compiler I use.

Does any

I take it that part of you post got cut off?

In either case,

* ulong can only be shifted by up to 63 bits
* uint can only be shifted by up to 31 bits
* ushort can only be shifted by up to 15 bits
* ubyte can only be shifted by up to 7 bits

Any code which attempts to shift by more than that is wrong. If you want to 
shift a value by the number of bits in its type, you might as well just use 0. 
If gtkD is attempting to shift by more than is legal, then it has a bug.

This was a bug in GtkD, getValue needs to return a ulong.
The fix has been in the git/svn repo for quite a while now ;).

Yeah, the README for GtkD said to use the packages from the dsource site...
Which are the ones that have that bug.

Maybe that should not be stated there...

Thanks for the info guys!

I downloaded from the github and everything works nicely now.

Sorry for the stupid question, probably should have just slept instead.
