Thanks for your efforts!

Using the current HEAD to build Python 3.12.2, under both macOS and Ubuntu 20, results in the following:

Hi @dbrnz! Is there a place for me to see how you're calling into the buildsystem from opencor?

commented

That was quick -- I see you already have a PR!

Our relevant CMake code is here but now tweaked to specify Python 3.12.2 from your branch. Simplest though would for me to reference your PR and re-build.

commented

I would recommend keeping PYTHON_APPLY_PATCHES enabled - the core patches for 3.11 and 3.12 were needed to get things compiled correctly. Patches specific to the portable Python project have recently been put behind a flag, disabled by default.

commented

Well, with PR #11 merged, but without PYTHON_APPLY_PATCHES, I have a working Python 3.12! Thanks!!

commented

Great! I'll merge that in
