While DDT technically work oks with GDB (the GDB from mingw-w64 that
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?
