Description

I am trying to build xorg-server (because Quartz X11 is apparently not compatible with M1/Apple Silicon. But I could not get past the python build:

python38+ should work, as it is there for arm64 <http://packages.macports.org/python38/python38-3.8.7_0.darwin_20.arm64.tbz2>

python38 is supposed to be our MacPorts default python at present.

Can you see what is calling for python37?

Thanks Ken,

I am installing xorg-server and this is why the python37 request. I will try to install python38 and see if xorg is happy with that. I have read that xorg-server works with Apple silicon so was surprised when it failed to make.

I am working on a full install of texlive now, so will that run to completion and then try to see about xorg-server again...

in port rdeps xorg-server I see:

    xorg-libxcb
      python38

but nothing wants python37.

comment:5 Changed 11 months ago by rsmacleod (Rob MacLeod)

OK, I did a port clean xorg-server first and then a clean install and the python dependencies are covered now...looking good so far...

Yeah, only python 3.9 currently properly supports Apple Silicon at present. Upstream is going to backport the fixes to 3.8 but hasn't done so yet. When they do, I may backport them further to the other non-EOL branches.

Replying to kencu:

3.8 will build, but at minimum will have serious issues with ctypes on arm64.

Replying to kencu:

python39 is supposed to be the default now, per [fa147a0a5b020635eb792a94330a0cc5641cc7b3/macports-ports].

Hey, that was probably the day after I changed my last port from python39 to python38 as that was said to be the default :>

Seriously, nobody knows when these defaults are changing -- I don't follow changes to that PortGroup.
