Re: Using D libs in C
I've tried compiling the same on Linux and the program still crashes (with segmentation fault there). No error message or anything. And it doesn't matter if I compile the thing from .obj or from .lib files, I still get the same crashes. So it's a real showtopper for me, since what's the use of having static libraries that compile successfully yet crash every time you attempt to use them?.. Anyone have any ideas about what's happening? Or should I just go ahead and submit this to the bug tracker?

Call rt_init before using your library and rt_term when your done with it. The D runtime replaces main with initialization code and renames the programs main to _Dmain. extern (C) bool rt_init( void delegate( Exception ) dg = null ); extern (C) bool rt_term( void delegate( Exception ) dg = null );
TDPL 6.4.3 Overriding Is Only Voluntary
"The override keyword in the signature of Friend.bgColor is required," (193)
This code compiles:
class Contact{ string bgColor(){ return ""; } }
class Friend : Contact{
string bgColor(){ return "LightGreen"; }
}
So how is 'override' required? Can I get an example of where
'override' makes a difference?

dmd is behind TDPL on several counts. This is one of them (
http://d.puremagic.com/issues/show_bug.cgi?id=3836 ). Eventually, override
_will_ be required. Right now, it's only required when compiling with -w.
