Re: [BRLTTY] Support multiple Python versions on Windows
Hi Samuel, I'm not sure whether the current implementation is enough. You added CYTHON_LIMITED_API, but it looks like you might also need to add Py_LIMITED_API.

Might there be a way on Windows to trace the execution of a program so that you can see which file it's actually looking for and where it's loking for it? On Linux, for example, I'd be using strace to do exactly that. -- I believe the Bible to be the very Word of God: http://Mielke.cc/bible/ Dave Mielke| 2213 Fox Crescent | WebHome: http://Mielke.cc/ EMail: d...@mielke.cc | Ottawa, Ontario | Twitter: @Dave_Mielke Phone: +1 613 726 0014 | Canada K2A 1H7 | ___ This message was sent via the BRLTTY mailing list.

Re: [BRLTTY] Support multiple Python versions on Windows
Thanks a lot Dave, I'll test this later today and will report back. Could you elaborate on the development environment you're using to create these packages? I have invested multiple hours in getting a build to work with msys1 based in mingw-get, but that tooling seems pretty old and out of date nowadays. I'm getting errors about windows error constants that could not be found.

Re: [BRLTTY] Support multiple Python versions on Windows
Hi Samuel, That is lovely! I'm happy to give that a try if I can get the Python bindings to build, though having a hard time with that. The windows building docs contain several suggestions for build environment. Ideally I'd use something that is as close as possible to the environment Dave uses for release builds.

Re: [BRLTTY] Support multiple Python versions on Windows
Hi Dave, Thanks for the quick response. May be I should setup a dev environment myself first to experiment a bit, but I'm slightly puzzled about the docs. What should I do if I want to create a x86 python module? Should I go with Cygwin or min-GW, and should it be explicitly X86 or can X64 builds of either cygwin or MinGW perfectly create X86 modules?

[BRLTTY] Support multiple Python versions on Windows
Hello all, particularly Samuel, The NVDA project is currently in the process of upgrading Python to version 3.11. I recall that when we updated to Python 3.7 3 years ago, I had to create a brlapi python extension manually, as the python version bundled in the Windows packages didn't match Python 3.7. Python has something like the stable application binary Interface (ABI), see https://docs.python.org/3.11/c-api/stable.html . This can be used by enabling the limited API. I wonder, has this ever been considered? If not, could it be considered to create a brlapi python package that uses the limited API, preferably using an API version that is equal to the minimum Python version that is still in maintenance (currently 3.8)? That would ensure that you'd be able to use a brlapi python extension with multiple python versions. Regards, Leonard ___ This message was sent via the BRLTTY mailing list.
