кто-нибудь знает, что с ldc2?
вот ldc2.conf

// See comments in driver/config.d in ldc source tree for grammar description of
// this config file.

// For cross-compilation, you can add sections for specific target triples by
// naming the sections as (quoted) regex patterns. See LDC's `-v` output
// (`config` line) to figure out your normalized triple, depending on the used
// `-mtriple`, `-m32` etc. E.g.:
//
// "^arm.*-linux-gnueabihf$": { … };
// "86(_64)?-.*-linux": { … };
// "i[3-6]86-.*-windows-msvc": { … };
//
// Later sections take precedence and override settings from previous matching
// sections while inheriting unspecified settings from previous sections.
// A `default` section always matches (treated as ".*") and is therefore usually
// the first section.
default:
{
// default switches injected before all explicit command-line switches
switches = [
"-defaultlib=phobos2-ldc,druntime-ldc",

// default directories to be searched for libraries when linking
lib-dirs = [
"%%ldcbinarypath%%/../lib",

// default rpath when linking against the shared default libs
rpath = "%%ldcbinarypath%%/../lib";

Ты с линукса хочешь под винду скомпилировать, так?

А уже не надо, достал девайс на винде и собрал прям там)

вообще он кросскомпилит буквально в несколько строчек конфига dub-a и даже без него: линкеру пробросить директории lib64 и lib64/mingw и слинковаться с ldc_rt.builtins, как обходной манёвр чтобы убрать ldc-шный конфиг с lib-dir. Здесь что-то похожее делали.
