hi,
i am following the DMD compiler since the 0.11* versions, and many new features
have been added, but there is no useful and usable debugging for the Linux
version.
Ok, I know that the line numbers now are ok, and i can watch global symbols, but
it would be cool if i could debug symbols that are allocated on the stack... It
would help me to develop my operating system in D :-)

I think Walter should wait to add new features, and make debugging work.

Sorry for my bad english :)

All the debugging symbols are present in the executables. I dont understand what you are asking for.

You know that GDB isn't D aware out of the box. However there is a patch avaliable.

All the debugging symbols are present in the DMD Linux executables?  I don't think so.  With my patch, I've gotten GDB to work with the line number information, but GDB doesn't see any of my variables, and neither do I with the dumpobj -g command.  I can't even see global variables in GDB.

ahhh ok yeah codeview is a microsoft format - I have specs for OMF codeview data - but I dont know if walter is emitting it in the linux version. Are you using GDC or DMD? All the CodeView 4 symbols are there from the DMD compiler in the windows versions. Ive been building a windows debugger and playing with the codeview symbols for some time. However - there is some problem that seem to prevent the standard debuggers and tools to read the data correctly, i have no idea what this is - but ive had no trouble with parsing the codeview data myself. also some people confuse OMF/COFF symbols with the codeview symbols - the OMF symbols are being stripped.

have you looked into parsing OMF Codeview 4 data from the executables?

I am using DMD under linux, and IIRC the Linux version uses the DWARF debugging format.

My problem is that I'm writing my OS under Linux, since it is more flexible, and so full debugging will help things a lot :-)

I am waiting for Walter's answer.

Hmm. Windbg.exe is able to read it correctly.

The linux version of DMD is not emitting CV4 info, or any symbolic info. Just line numbers.

how is windbg able to identify things such as local arrays?

BTW, I was refering to microsofts dbghelp.dll - which seems to choak on DMD executables. At least I couldnt get it to work very well. However Im still interested to know how windbg handles arrays.

Windbg doesn't know anything about D types. So the D types are represented as the nearest C type. For dynamic arrays, unfortunately, this would be a 64 bit "long".
