ddd 3.3.8

[Wayne E. Van Loon Sr.]

Dear Folks:
I used to use ddd 3.1.5 extensively. It came with an old distribution 
that I used for several years.

Recently I updated to Slackware 9.1 and downloaded ddd 3.3.8 
(i686-pc-linux-gnu). I hate to complain, but ddd isn't half of what it 
used to be. I look at the ddd website, and all kind of wonderful things 
about ddd.

In my case, a lot of things don't work anymore or they don't work right. 
I thought I would mention some of what I have noticed as maybe ddd 
really does still work but I have something wrong with my setup / system 
(Athlon, pc, Slackware 9.1, Linux 2.4.22, gcc 3.2.3).

In the data display:

1. You can't drag a display. After it gets placed, that's it. When I 
attempt to drag a display item, I get the little four directional 
arrows, but the display will not move.

2. I can't delete a display. The Undisplay option is there, it just 
doesn't do anything.

3. I can't expand an array that might be part of a structure using
"Show  All" in the pop-up menu after right clicking on the array.

4. I can't dereference a pointer that might be a member of structure.
I used to be able to right click on the pointer and then move the cursor 
to the Display *() in the little popup window. On my system, the
Display *() is grayed out.

5. Set Value doesn't seem to be available, it also is grayed out.


I recently used ddd to debug some QT code. This may be something that 
the QT Meta Object Compiler (moc) causes, but I can't set a breakpoint 
in any file other than the file with the main function. When you attempt 
to set a breakpoint, it looks like you have set a breakpoint, but ddd 
will blow right by it when the program runs.

The only way I could use ddd was to write a little function that I put 
in the file with my main function and call that function from the file 
that I wanted to debug in. If I put a breakpoint the the little 
function, I could single step back into the file that I really wanted to 
debug.

I loved the old ddd. I know that it had some memory problems, but it was 
damned useful. I sure hope there is some simple mistake that will soon 
be fixed.

Sincerely
