Why some ports seem to install universal when I do not request it ?

[Christopher Jones]

Hi All,

Just migrated from an intel to AppleSilicon machine.

Reinstalling MacPOrts, from scratch off course, I’ve noticed some ports get install universal, when it’s not something I have requested. e.g.

--->  Fetching archive for zlib
--->  Attempting to fetch zlib-1.2.13_0+universal.darwin_22.arm64-x86_64.tbz2 from https://packages.macports.org/zlib
--->  Attempting to fetch zlib-1.2.13_0+universal.darwin_22.arm64-x86_64.tbz2.rmd160 from https://packages.macports.org/zlib
--->  Installing zlib @1.2.13_0+universal
--->  Cleaning zlib
--->  Deactivating zlib @1.2.13_0
--->  Cleaning zlib
--->  Activating zlib @1.2.13_0+universal

zlib has a universal port, but its not a default one, and I didn’t request it, nor have I ever set my default settings to always install universal.

As I am new to apple silicon machines, is this normal ?

cheers Chris
