Very simple thing from https://dub.pm/getting-started/first-steps/

After I add dependencies, it cannot build:

$ cat dub.json
{
        "authors": [
                "mw"
        ],
        "copyright": "Copyright © 2024, mw",
        "description": "msgpack-rpc-d demo.",
        "license": "MIT",
        "name": "demo",
        "dependencies": {
                "msgpack-rpc": "~>0.1.3"
        },
        "subConfigurations": {
                "msgpack-rpc": "default"
        }
}

$ dub build
Could not resolve configuration for package demo

So what I'm missing?

Thanks.

Trying to build your dependency msgpack-rpc, it spits out

     Warning The sub configuration directive "vibe-d" -> [libevent] references a configuration that does not exist.
Error Could not resolve configuration for package msgpack-rpc

In version 0.7, vibe-d depended on libevent, this got removed in the meantime
https://github.com/vibe-d/vibe.d/commit/196096407ec27b2c107f0038c6751ce07e7a9507

Just patching msgpack-rpc dub.json to use the exact vibe-d version, and not a minimum, like this

	"dependencies": {
		"msgpack-d": ">=0.9.2",
		"vibe-d": "==0.7.25"
	},

fails too, because this old vibe-d version doesn't compile anymore.

You'll have to either fix the old vibe-d version, or fork msgpack-rpc to work with current vibe-d, whatever is more appropriate and easier.

OK, looks something wrong with dub / or vibe-d 0.10.0

https://github.com/msgpack-rpc/msgpack-rpc-d/blob/master/examples/with_http_server/dub.sdl#L5

with

dependency "vibe-d" version="~>0.7.25"

dub build can at least starts.

But

dependency "vibe-d" version="~>0.10.0"

$ dub build
Error Could not resolve configuration for package with_http_server

Thanks for the reply.

But where you see this warning message? I didn't see it even with $ dub build -v.

I'm trying to fix it with the latest vibe-d 0.10.0, now the new error:

../../src/msgpackrpc/transport/tcp.d(13,8): Error: unable to read module `driver`
../../src/msgpackrpc/transport/tcp.d(13,8):        Expected 'vibe/core/driver.d' or 'vibe/core/driver/package.d' in one of the following import paths:

that line is:

import vibe.core.driver;

Do you know where is vibe.core.driver in the new version?
