I've created a Dockerfile [1] containing LDC, configured for cross-compiling targeting Windows x64. It's based on the instructions provided by kinke here [2]. Note, it downloads the MSVC libs from Dropbox.

The only obstacle may be that the build requires a C cross-compiler for one or two C files, but clang may be good enough to do that now. If you go that route, the ldc devs would appreciate a PR filling out this preset configuration stub to cross-compile for Windows, with the info you use: https://github.com/ldc-developers/ldc/blob/master/runtime/PresetRuntimeConfiguration.cmake#L46

See also: https://hub.docker.com/r/dlanguage/ldc (dub seems to still default to writing `.a` object files) BTW I just tested this and it works really nicely (I even managed to compile the whole DScanner for Windows (!) and it runs as expected in a quick test in a virtual machine). Thanks! Now how do we get this to DockerHub? :) Any MS libs that can be bundled "legally"?I've created a Dockerfile [1] containing LDC, configured for cross-compiling targeting Windows x64.

Thanks!Thanks for the confirmation.Any MS libs that can be bundled "legally"?That's the problem. If there were, they'd be bundled with the LDC Windows packages, so that LDC on Windows wouldn't require a Visual C++ installation anymore and just work out of the box. To avoid confusion: we're talking about the static and import .lib files of the Visual C++ runtime & Windows SDK, not about the redistributable DLLs. The libs on DropBox are from Visual Studio 2015 Update 3, while the LDC 1.8 druntime/Phobos libs have been compiled with latest VS 2017, so this divergence could become problematic at some point.

I'd also prefer to keep on defaulting to the static C runtime in order not to produce binaries depending on Visual C++ DLLs (hindering portability of Windows binaries).
