If you are building individual files, use ldc2 with
--link-defaultlib-shared flag:
arun@home-pc:/tmp$ cat a.d
void main() { import std; writeln("Hai"); }
arun@home-pc:/tmp$ ldc2 a.d

If you want similar behavior with dub, here is a sample dub.json
arun@home-pc:/tmp/test$ cat dub.json
{
"authors": [
"Arun"
],
"copyright": "Copyright © 2019, Arun",
"description": "A minimal D application.",
"license": "proprietary",
"dflags-ldc": ["-link-defaultlib-shared"],
"name": "test"
}
arun@home-pc:/tmp/test$
Dub settings can be at times intimidating, but still give it a
read https://dub.pm/package-format-json#build-settings
Thank you Arun, that is very helpful!
Do you have also some example which use some other than default
library ?
I see there is quite comprehensive description how to use dmd
with dynamic libraries
https://dlang.org/articles/dll-linux.html
But there is nothing how to integrate it with dub and deb.json (I
really like DUB, it's one of the best improvements over C/C++
enviroment I noticed)
Also where is RDMD in the equation? I really like the idea run
binary programs like:
#!/usr/bin/env rdmd
import std.stdio;
void main(){
writeln("Hello, world!");
}
But I cannot find any documentation how to use rdmd with any
libraries/dependencies and dub.json ? Not even statically linked,
not to say dynamic.
