Unfortunately in this particular case, CDT's debugging is pretty
fancy and is going to need most if not all of the MI.

While DDT technically work oks with GDB (the GDB from

is), you are right, there isn't a compiler on Windows that
supplies
debug info in the way GDB understands. See
https://wiki.dlang.org/Debuggers.
DMD produces debug info COFF or OMF format, which GDB doesn't
know
anything about (nor ever will). LDC should in theory work
with DWARF
info, but this is broken somehow. Not because of LLVM though,
since
for example Rust on Windows works. As for GDC, it doesn't
even supply
binaries for Windows (that target Windows) - it is not a
supported
platform.
BTW, Eclipse/DDT should in theory work with mago-mi as well,
at least
if the protocol is implemented correctly. Have you tried it?
I dunno
how complete your MI implementation is.
So it looks like mago-mi might be helpful for DDT on Windows.
mago-mi supports subset of GDB/MI commands enough for
DlangIDE, but it
can be easy extended.
Currenlty supported commands can be shown using help command
(use
--interpreter=mi2 when running mago-mi, otherwise it will
print non-MI
commands). Also commands are listed in readme file
https://github.com/buggins/mago/blob/master/MagoMI/mago-mi/README.md
I didn't try DDT with mago-mi, and so I'm not sure which
commands must
be supported by debugger to get it working with DDT.
To get list of commands DDT tries to use you can either add
--log-file=magomi.log --log-level=TRACE to mago-mi command
line or use
debug build of mago-mi.
It will all STDIN data to log file, and report errors for
unsupported
commands.
I also don't know which MI commands need to be supported to
have it work with DDT. The thing is I didn't write the GDB
debugger integration for DDT, I just reused the one from CDT.
So I'm not that familiar with those internals.
BTW, the MI integration is fairly language agnostic, so in
theory your debugger could be used by CDT to debug C/C++
programs too, no? At least those generated by DMC. Maybe Visual
Studio ones too?
I'm experimenting with the build of mago-mi that comes with the
current ~master for dlangide, and it seems to throw an
unrecognized parameter error when on the --log-level=TRACE
parameter.
And it seems that the version string it returns upsets eclipse,
as it throws the following error:
Could not determine GDB version using command:
D:\WinHome\<redacted>\AppData\Roaming\dub\packages\dlangide-master\bin\mago-mi.exe --version
Unexpected output format:
mago-mi debugger v0.1
Though, from my experience using it in Linux, eclipse-CDT's
debugger seems pretty full-featured; it will likely require large
swaths of mi functionality to be fully useful.
