Hi guys, for a possibly-in-over-my-head project I'd like to get 
working a simple "Hello World" type program in which I call a D

in plain D with bindings to libctru). The thing is, I'm not 
skilled with Makefiles so I don't have a clue on how to correctly 
set up the toolchain for linking everything. I can compile some 
D-calling C code just fine with dmd and gcc on Linux (though I 
can't get anything working with gdc for whatever reason). Would 
anyone be able to point me in the right direction?

This is the example Makefile for a 3DS homebrew app: 
http://pastebin.com/fcJrrMg9 It seems like there would be issues 
differentiating the .d build definition files from D source 
files...

Thanks!

Hmm.

I apologise that this post is not in any logical order.

dmd can only compile for x86 so you will have to use ldc or gdc

makefiles are generally not used in d. you should be able to use
the dub project settings file (dub.json or dub.sdl) to do most of
the standard linking, as for some of the deeper magic I'm not 
sure.

versioning: i'm not sure that d has a 3ds target version but it 
has
an arm one. includes should not be an issue.

If you cannot find bindings for ctru see if dstep can do it for 
you.

I don't know what .v.pica or .shlist files are but you can use
string imports to reference the data looks like the same idea
can be used for the shader rule. However you may need to use a 
prehook
script to call whatever "picassso" does first.

Thanks for the suggestions. I know I need to use gdc, 
specifically the one found at 
ftp://ftp.gdcproject.org/binaries/devkitARM/ (or build it myself 
if this doesn't work for whatever reason).

I'm starting to think a bigger problem aside from the Makefiles 
is just getting any D to compile with that gdc version at all. 
I'm pretty sure I need some sort of bare metal runtime. Would 
this be something that could work, or should I look elsewhere?

...This probably really is above my knowledge level, but I 
suppose I'll never learn if I don't give it a shot. Like I said, 
if anyone has any sort of advice on how I should approach this, 
I'd be happy to hear it.
