Hi,
I recently ran into the same issue. Here is some dirty workaround I came up with..
Look up the dub package of vibed, it should be in %appdata%\Roaming\dub\packages\vibe-d-0.7.29-alpha.3
Open vibed's dub.json, scroll down to configurations and change the entry with name libasync to the following:
{
"name": "libasync",
"targetType": "library",
"subConfigurations": {
"vibe-d:core": "libasync"
}
},
Finally, in your own dub.json add subConfigurations": { "vibe-d": "libasync"}
Best Regards!
