Hi,

In my dub.json, I have:

            "dependencies": {
                    "apache-thrift": "==0.16.0",
                    ...
            }

            "subConfigurations": {
                    "apache-thrift": "use_openssl_1_1",
                    "pyd": "python39"
            },

But:

$ dub build
Unresolvable dependencies to package openssl:
  apache-thrift 0.16.0 depends on openssl ~>2.0.3
  apache-thrift 0.16.0 depends on openssl ~>1.1.6
  app ~master depends on openssl ~>2.0.3

Why the subConfigurations: "use_openssl_1_1":

https://github.com/apache/thrift/blob/master/dub.json#L26

    {
      "name": "use_openssl_1_1",
      "versions": ["use_openssl_1_1_x"],
      "dependencies": {
        "openssl": {
          "version": "~>2.0.3"
        }
      }
    }

did not pick up the 2.0.3? but report conflict instead?

Thanks.

This is a known limitation -- dub builds the selections file based on all configurations in the file. If you have conflicting ones, it will not know what to pick.

However, if you manually construct the selections file, then it will work.

See https://github.com/dlang/dub/issues/1217
