Do we know what goes wrong in this case? It seems to be universal-only issue, since I have mpich-gcc10 for ppc on 10.5.8 and mpich-gcc11 on 10.6 PPC built.

Replying to kencu:

this:

Error: Failed to destroot mpich-gcc11: /opt/local/lib/mpich-gcc11/libmpi.la differs

Yeah, but why? Any ideas how to fix?

[kencu (Ken)]

Oh, sure, I know how to fix it, but I thought you had been stuck for months and months and just needed a clue to get yourself started.

Step 1 is to look at the two la files and see why they differ. These are just text files, so open them both up in a text editor.

Usually it is very minor stuff, like timestamps or comments -- meaningless stuff. If that is the case, and it almost always is the case, then you have two choices.

1. copy on onto the other in a pre-destroot block. This is easy enough, but it takes a moment to work out the exact copy, of course.
2. disable the error. I do this myself, manually, in the muniversal PG in my personal tree, by changing the comments in this bit here to disable the error and copy in one of the la files.

​https://github.com/kencu/kencu-ports/commit/323ceed0164869dc145fc5277753034477ab33c4

That trick, of course, would not be acceptable to a macports admin in general, so you have to do the other thing.

Whenever you see that two files differ and cannot be merged, this is the approach to take. If they are text files, almost always it is some trivial thing. Sometimes, it is more complicated, which is why the PG flags it as an error -- to make you look at it..
