 Posted: Thu Jul 16, 2009 7:02 pm Post subject: some questions and a devenv crash |
 |
|
First of all, I just tried out this wonderful tool, thank you very much for that. Really helps a lot.
I used ddbg so far, but it is too buggy and not updated anymore 
I got some questions:
* Is there a way to make dmd or cv2pdb include the standard library source code in the debug information?
I have some code using std.zlib but apparently that source isn't included , I can only look at the disassembly.
* so far I couldn't find a way to get a list of all included files/functions, I always have to step into the code, manually enter the function with its fully qualified name in the disassembly window, set a breakpoint there and run the code until it breaks. Then the source file is opened.
Furthermore my VS2005 crashes.
I set a breakpoint at the first line of std.zlib.uncompress and run, then hover the mouse over the srcbuf parameter (or switch to the Autos or Locals tab) and it crashes with "unknown software exception" (0xc000000d) occured at position 0x78144584.
Haven't had the time to test if this happened just for that particular data, though. |

Did you build the library with debug info? This works for me as of version 0.5 of cv2pdb.

This is what happens if you try to debug an executable created by DMD without converting it with cv2pdb. Another symptom is that you cannot set breakpoints in the source files.
I guess something has gone wrong with the conversion. I'd suggest not to convert "in place", but to create a different executable by passing a second argument to cv2pdb. If this fails, please file a bug-report and attach the original executable.
As far as I know, Visual Studio doesn't list files or functions of a debugged executable, but if you open a source file, setting breakpoints works for a cv2pdb-converted executable.

I cannot verify right now, but have you tried without the entries in autoexp.dat (though they should not do much if conversion has failed anyway). To reproduce, knowing your version of DMD might be necessary.

Thanks for your reply.

I'm compiling using dsss(i.e. rebuild) with -debug -g. So I guess I have to recompile the phobos.lib in the dmd directory.

I did convert it with cv2pdb and setting breakpoints in the source files works, but I don't know how to open them  As I said, they don't open until I reach their code in the disassembly window.

Will try.

May try that out, I'm using latest dmd 1.046. |

Yes, that is necessary.

Have you tried the "Open..." command from the file menu?
While you are not debugging, setting breakpoints might seem ok, but once you start the debuggee, the breakpoint indicator circle no longer stays opaque if it cannot be resolved. |
