So the compiler can generate debugging information. How do we use it? Is there some program available that supports D debugging info?

Any debugger that uses standard debugging information. If using linux, you can use gdb. If using Windows, you can use, for example, Microsoft's windbg.exe program (which comes on the DMC++ CD).

gdb seems not working, or I miss something?

I'm no expert on gdb, but I am able to get it to work. I don't know why it couldn't find hello.d for you, is it in your default directory?

All the command is issued from the same dir:

dmd/samples/d

so it should be able to see hello.d

Which version of gdb you're using?  and which Linux distribution (RedHat 9.0)?

What's the word on this?
I'm trying to use gdb (with DDD frontend) and having the same
problem.
I can see all the GTK+ sources (C of course) but not
my D program (some DUI test).

Can some post the status of debuging on linux?
An entry on the wiki FAQ would be nice.
