"Linking Executable" errors when running in 64-bit

General

I am attempting to run our GUI on the Mac in 64-bit for the first time and am getting a series of “Linking Executable” errors. Any ideas?

Linking Executable

SetDragImageWithCGImage is Carbon Drag & Drop API.

So please remove use of SetDragImageWithCGImage.

QDBeginCGContext and QDEndCGContext are from QuickDraw to work with CGContext. They are deprecated and not available for 64-bit, so remove them, too.

Ah, I see, it’s a declare in the CustomEditfield code. Thanks Christian.
