Error: ld64: Variant ld64_274 conflicts with ld64_xcode

I am migrating my port from 10.11.6 to 10.15.7:

Error: ld64: Variant ld64_274 conflicts with ld64_xcode

Thanks. The way MacPorts handles upgrading default variants is in need of some fixing. There is an open ticket in the 4000 series about this that I don't have time to reference right here, but this issue has drawn attention in the past month as a problem.

I recently made some changes to how cctools works to try to prevent this kind of thing happening, so I will look at the ld64 port to do the same.

For now, obviously, don't try to install ld64 @3_3+ld64_274 on 10.15 as it is not meant to work there.

The solution, to paraphrase from what I did in cctools, is to not even make that ld64_274 variant visible on 10.15, and then it disappears from history.

How about this:

Error: Requested variants "" do not match those the build was started with: "+universal".
Error: Please use the same variants again, or run 'port clean libiconv' first to remove the existing partially completed build.

I ran 'port clean libiconv' and manually installed readline, ... but I get the same error.

Replying to dbl001:

How about this:

well there you got yourself a whole new problem that has (AFICT) nothing to do with this here ld64 problemo.

Create a new ticket?

I believe this has been improved or fixed in base with the "requested variants" thing.

at any rate, nothing to do with ld64 directly.
