found Cython version 3.1.0a0
That's not a supported version - please try with the stable 3.0.x series.
error: Couldn't find a setup script in /tmp/easy_install-qvk3o6gl/pygobject-3.48.1.tar.gz
Something is wrong with your environment, it looks like something is trying to install pygobject - which should already be installed.
The xpra ./setup.py file does not do that on its own.
xpra/x11/bindings/core.pyx:92:40: undeclared name not builtin: long
Very likely caused by the alpha build of Cython.
return "".join([chr((vid_format.fmt.pix.pixelformat//(2**(8*x))) % 256) for x in range(4)])
Same. Perhaps 0ccc5c8 will help. (untested)

Thank you very much. Will try using the released versions (which was what I was going to attempt anyway.)
Hoping to provide some feedback rather soon. Thank you.

The python setup.py install --minimal worked on the v5.0.7 tag of the xpra repository. Not on the latest master branch. My issue thus seems "temporarily" fixed.
Closing.
Thank you.

Unless you share the problem you encounter with master, this will not be fixed in future versions.

OK. So I'll try to follow up. In two parts.
Part 1.
TL;DR: Building xpra 5.0.7 against cython 3.0.10 works, but doesn't work against cython 3.0.x (commit b197288e92f, i.e. the 3.1.0a0 cython version which is on the 3.0.x branch). This seems like a cython regression in gestation.
Instructions used for cython: python -m build --wheel followed by pip install dist/*.whl.
Instructions used for xpra: python setup.py build followed by python setup.py install. (I did not use --minimal this time.)

Cython.Compiler.Errors.CompileError: xpra/net/bencode/cython_bencode.pyx Part 2.a (without the --minimal flag):
TL;DR: Building xpra 5.0.7 against cython 3.0.10 works, and building xpra master (commit 35ada47) against cython 3.0.10 also does work. The build instructions are the same as in part 1.
Part 2.b (with the --minimal flag):
TL;DR: Works fine too.
I guess my issue is that I was using a --prefix that wasn't very standard.
So all good. I'll keep this issue closed.
Thank you.

This seems like a cython regression in gestation.
Not so much a regression as a long deprecated feature removal.
n = long(x[f:unewf])
xpra/net/bencode/cython_bencode.pyx:48:12: undeclared name not builtin: long
This code has already been removed from xpra v6.
If you want to run bleeding edge Cython, you should probably also run bleeding edge xpra.

As per above, there is a workaround in git master: 0ccc5c8

Makes sense.
