Cannot install under Python 3.10

[cowwoc]

When attempting to pip install JPype1 under Windows 10 I get:

Python 3.9 used to work just fine.

I've also noticed that, see GitHub Actions run on my fork. Builds on Linux and macOS are fine. Only builds on Windows 10 with Python 3.10 produce these strange syntax errors. Same with the py3.10 branch.

[Thrameos]

Seems like a missing include. I see other projects have hit this. Not sure why we would be getting this now. Mostly likely Python changes their includes and something we assumed was included is now missing.

vlm/asn1c#159

[Thrameos]

I converted all the ssize_t to Py_ssize_t which should fix this compiler issue. It will be included in the next release.

[john-hen]

You missed a spot.

jpype/native/python/include/jp_pythontypes.h

Line 284 in 9c210eb

PyObject* operator[](ssize_t i)

But then it builds with Python 3.10 on Windows.

[kamikaze]

same issue here. any ideas how to solve that?

[Thrameos]

Just waiting on the PR to go through. You can get the fix from the PR.

Still getting this issue in Windows 11, Python 3.10 while trying to install JayDeBeApi. Output attached.

Sorry, I should have read the whole thread. We have replaced ssize_t with Py_ssize_t a long time ago. Is Jaydebe using an outdated version of JPype?

[john-hen]

The latest release, JPype 1.3.0, does not contain the fix discussed here, @marscher.

[marscher]

Right, but is fixed on master, so we need another release to get Python-3.10 working.

[Thrameos]

Yep. Tis why I have been trying to get the issues closed out. Hopefully this weekend, if work will let up.

I have the same your issue, and I solved it by steps:

1. go to this link https://www.lfd.uci.edu/~gohlke/pythonlibs/#JPype and download the wheel
   ex: JPype1‑1.3.0‑cp310‑cp310‑win_amd64.whl
2. using pip to install package just downloaded
   pip install --find-links C:\Temp\ Jpype1
   with C:\Temp is a folder contents your package
3. install JayDeBeApi
   pip install JayDeBeApi

Hope this help
