How do I link in the run time and gc, etc?
In your case, you firstly need to cross-compile druntime to your
target. This means compiling most files in the src subdirectory
of LDC's druntime [1], excluding obvious ones like
src\test_runner.d, src\core\sys, src\core\stdcpp etc. There are
also a bunch of C and assembly files which need to be
cross-compiled with a matching gcc. You'll need to do this
manually via something along these lines:
cross-gcc -c <.c files and .asm/S files>
ldc2 -mtriple=... -lib -betterC -release -boundscheck=off <.o
files generated above> <list of D source modules>
-of=libdruntime.a
Then try linking your minimal code against that druntime (and
static C libs, as druntime is built on top of the C runtime, see
[2]). Depending on what features you make use of in your code,
you'll need to patch linked-in druntime modules to remove the OS
dependencies and possibly reduce the C runtime dependencies as
well.
