digitalmars.D.ide - Setting up GDB debugger with Eclipse

Hi, I'm new to this group and Eclipse. I have installed Eclipse

HelloWorld.d prints the correct output to the console but there 
doesn't seem to be any debug activity.

Here are some screenshots of the Eclipse menus:

The "no symbol table load" message indicates the file does not have 
debug information compiled in. How did you compile the executable?

The "no symbol table load" message only displayed a few times. I 
think I compiled it using  Project -> Build Project and this is 
how I ran the executable:

This is where I am at with the debugger, it says it has no line 
number information:

When GDB says function main has no line number information, it's 
referring to the C runtime main function, not the D main from 
HelloWorld.d . Normally none of the C runtime will have debug information.
In that situation, if you place a breakpoint int the writeln("Hello 
world!") line, and then resume execution, it should run up to that 
point. Give that a try.

I have found the problem and now the debugger works as can be 
seen in the screen-captures below. The compiler DMD was not being 
given the -g argument.

Right-click project

Click project properties

Resize window

Emplace -g as argument for compiler

Click debug
http://tryimg.com/4/10deb.png

No source available, close that.

Click Step-Over, reaches breakpoint

Click Step-Over again, execution steps forward

That works, although the original intention was that "-g" option should 
be added in its own line in the "Managed response file" field.
It actually should be added by default, so maybe it didn't due to a bug.

In any case it doesn't matter anymore, all that functionality has been 
removed in the upcoming version of DDT, replaced by the DUB builder.
