The point, for me at least, was not weather I could use GCC + MS debuggers or MS compilers + GDB. It was: if you use DMD (64 bit ATM) what debuggers can you use? Can you sucessfully use GDB? If not, could DMD be modified to supported whatever format GDB uses? Also, it's not likely DWARF debug information that it emits, as the COFF object format defines its own intrinsic symbolic debug format. GDB can't read CV8/PDB. I think it's DWARF debug information, even for COFF and PE file format. If I run info source on a GDC compiled program, I get: -- (gdb) info source Current source file is ../../../gcc-4.6.1/libphobos/rt/dmain.d Compilation directory is C:\crossdev\gdc\v2\build\i686-pc-mingw32\libphobos Source language is d. Compiled with DWARF 2 debugging format. Does not include preprocessor macro info. -- I suspect that what is happening is that by default GCC toolchain stores debug information in the COFF (and PE) file format in a non-standard way - it doesn't use the COFF debug standard but uses DWARF data format instead (DWARF is independent of object file formats). And that's why MS tools don't understand that symbolic info, I guess. -- Bruno Medeiros - Software Engineer

Almost all dev tools/environments/libraries are distributed as MS-COFF libs. GCC COFF output isn't very useful in the windows context. I tried it. It tried to link, but GCC produces countless intrinsic calls to the gnu runtime libs, and they are quite incompatible with the MS CRT. It also seems to populate the COFF objects with DWARF debug info instead of CV8 that VisualC's linker extracts and writes into a PDB file, so you can't debug GDC's COFF output with standard tools. So if you're not interacting with the MS ecosystem (the de facto standard on windows), then you might as well just use elf + dwarf from GCC. I guess the usefulness of Mono-D in windows is an environment that DOES support building+linking+debugging elf+dwarf based projects. This does exclude DMD, since it primarily tries to work in conjunction with the OS standards, but there's plenty of reasons to want to work with GDC in windows, and Mono-D would be the go-to environment for that. Ideally I'd like a command-line choice of object+debug format from all compilers so they can work in either of windows's fragmented ecosystems... but due to the intrinsic calls to glibc thing, GDC doesn't seem like it will ever be a good match for developing windows code. LDC seems promising that it may support either ecosystem, and DMD could theoretically write ELF+DWARF on a command line switch (it obviously has code to write those formats), but I haven't seen much demand for it.

So whatever it writes is apparently not recognised by link.exe (mustn't be VC8?)... I'm aware GDB can't read CV8/PDB, I'm not sure what your point is? I was just adding detail to your post about the state of COFF support in Windows. If you are using GCC, you'll be using the GCC toolchain. If you are using MSVC, you'll be using the MSVC toolchain. It's as black and white as that. Yes, that's basically the point I was making... and it influences your choice of D compilers, and tooling, hence Mono-D has a place in Windows even though it may not support DMD for debugging. So if you're not interacting with the MS ecosystem (the de facto standard on windows), then you might as well just use elf + dwarf from GCC. Except that GCC does not emit ELF on windows. ;-) Really? What is it? Well whatever object format it is, it seems it's not COFF by default, and appears it does support DWARF since I've debugged GCC code with GDB before.
