I'm working in BAS(Building Automation System) sector, and I
use Dlang daily for some advance products targeting ARM/Mips
boards.
D on Glibc/Linux/ARM works great today! It is well supported
and getting LDC to cross-compile is as easy as those 100 and
so words say! I'm using Ubuntu shell on Windows (WSL) and this
makes things even more exciting. Actually the hardest part is
getting the C cross tool-chain for your system, not LDC, I
find this pretty amusing.
A tutorial or guide on "cross tool-chain for your system" will
be very helpful. Say in ARM. Not that obvious to someone like
me.
Recently I had to port the software to uClibc/Linux/ARM, hence
my latest efforts on the port have followed with some patches
for Druntime, Phobos and LDC. I think, minus 2 PRs, it is
pretty close to complete. On my target system I've got it
working including vibe.d.
Nice. Vibe.d sound great!! Especially for IoT stuff. Get some
Pi to talk to APIs and services.
I suggest that you give it a try, and if you find issues
contribute!
For LDC on ubuntu is is pretty straight forward
1. Get cross tools for ARM, let's say ARM HF (hardware floating
point)
sudo apt-get install gcc-arm-linux-gnueabihf
2. Install LDC
3. Build cross libraries for LDC
From https://wiki.dlang.org/Building_LDC_runtime_libraries:
mkdir ldc-arm-linux-hf
cd ldc-arm-linux-hf
CC=arm-linux-gnueabihf-gcc ldc-build-runtime
--dFlags="-w;-mtriple=arm-linux-gnueabihf"
--targetSystem="Linux;UNIX"
Your cross compiled druntime and phobos libs will be the result
of this step, they are located in the
`/path/to/ldc-arm-linux-hf/lib` folder.
4. Compile your code
ldc2 -mtriple=arm-linux-gnueabihf -gcc=arm-linux-gnueabihf-gcc
-L=-L/path/to/ldc-arm-linux-hf/lib awesome.d
You now have an linux arm hf binary that can run on your target
device.
