Local libraries/packages with dub: How?

Dec 01, 2020

How does one set up a dub package so that it contains multiple sublibraries that may or may not depend on these same libraries?(but never co-dependant) So far i've tried using add-local and add-path with subpackage declarations in the root folder's dub.sdl but to no avail. (dub does not complain but silently doesn't add dependencies with -v, dmd just errors out with the standard file not found error "module y is in file y.d which cannot be read", with the path of my libraries absent from import paths.) Alternatively, is there an equivalent of -version= for DUB's build command?(for when a package author didn't add a config that incorporates the desired versions.) Big thanks and my apologies if this is the wrong place for DUB discussion.

dub add-local, adds a directory as a known package that it can use as a dependency (or to be executed). You need to specify in the package that depends on the dependency what dependencies you have. I.e. See the dependencies key: { "name": "myproject", "description": "A little web service of mine.", "authors": ["Peter Parker"], "homepage": "http://myproject.example.com", "license": "GPL-2.0", "dependencies": { "vibe-d": "~>0.7.23" } } See[0] how to specify the dependency itself. To have different sets of dependencies/code you can use sub packages or configurations. But I would suggest to just focus on one set for now, while you are getting the hang of the basics.

What puzzles me is that the dependencies are indeed declared, but "dub describe" refuses to recognize the dependencies and "dub build" fails. "dub list" does recognize the root folder, but trying to get a subpackage to import another fails because the dependency isn't imported.(dmd only sees the "source" and phobos/runtime import paths) The root dub.sdl roughly contains this : >name "fldr" >dependencies "fldr:spkg1" "fldr:spkg2" "fldr:spkg3" // tried with and without "fldr:" >subPackage "./spkg1/" >subPackage "./spkg2/" >subPackage "./spkg3/" >targetType "none" While for example, "spkg3"'s dub.sdl contains this : >>name "spkg3" >>dependencies "fldr:spkg2" And its source/*.d file contains this : >>>import std.stdio, fldr.spkg2; //tried with and without "fldr." >>>void main() {writeln(«function from spkg2»)}
