digitalmars.D.ide - Debugger on Codeblocks with DMD and Tango on Linux

Hi all,

did anybody manage to make the debugger work with the above environment
(Codeblocks 8.02 or the current 'Nightly Build', current Tango + DMD
package with DMD 1.033, gdb 6.8 from Debian Testing)?

If I set a breakpoint and then start the debugger, I get:

-------------------
Starting debugger: 
done
Registered new type: wxString
Registered new type: STL String
Registered new type: STL Vector
Setting breakpoints
Debugger name and version: GNU gdb 6.8-debian
Child process PID: 3642
-------------------

This looks OK to me so far, but there is no debugger arrow shown. Obviously
something happens when I press F7 (Next line), because every time I do, I
get messages like

-------------------
In _D6dmain24mainUiPPaZi7runMainMFZv () ()
In _D6dmain24mainUiPPaZi7tryExecMFDFZvZv () ()
In _D6dmain24mainUiPPaZi6runAllMFZv () ()
In _D6dmain24mainUiPPaZi7tryExecMFDFZvZv () ()
-------------------

... and finally ...

-------------------
In main () ()
In __libc_start_main () (/lib/libc.so.6)
Program exited normally.
Debugger finished with status 0
-------------------

... but still no yellow arrow. 

Any ideas on what is wrong?

Best regards and thanks in advance,
Timo

I don't use gdb but I've heard you need to apply some patches for better D  
support (like variable and function names demangling etc). Take a look  
here: http://dsource.org/projects/gdb-patches/browser/downloads/gdb6.8

That's all I can help you with.

Hi!

Thanks a lot, didn't know about this.

I patched and compiled gdb 6.8, but the unfortunately the behaviour is still
the same.

Best regards,
Timo

If you don't get the same problems when doing the same build/debug from
the commandline, it might be a bug where -g is not properly passed...

I believe the logic (inherited from C/C++) might only pass -g when 
compiling which might not be enough. Or, it could be something else.

PS. Testing the same thing with GDC would also help isolate the problem.

Yeah, make sure compiler and linker get the "-g" flag.

1) Compiler settings -> Compiler flags -> check "add symbolic debug info  
[-g]" (and, optionally, "compile in debug code [-debug])
2) Linker settings -> Other linker options - add "-g".

Hi Denis and Anders!

I already had -g and -debug checked in the compiler settings. I added -g in
the linker options and tried to debug again, but unfortunately it does not
make any difference.

The funny thing is that the breakpoint I set is nevertheless somehow
recognized by gdb. In spite of having no arrow and variable watches, I can
obviously step through the lines of the code by pressing F7 and get some
output. If I do not set a breakpoint, the debuger rushes through the code
and finishes immediately.

Thanks for all your help and efforts. Maybe this is rather a topic for the
CodeBlocks forum (although there are only very few D programmers there). 

KR,
Timo
