1 month ago I hope this is the correct location to ask about such an issue.
Indeed it is.
Okay, so there are a few issues here. The first is that binary wheels are provided for many common platforms but not for Linux aarch64 (gh-105) which I'm assuming is your platform.
Are you on Linux aarch64?
Those wheels will hopefully be added soon, but we're basically waiting for GitHub Actions to provide the runners that could build and test them.
The second issue is that building from source with the current release (0.6.0) uses setuptools which does not check the Flint version.
Can you try installing the latest prerelease with one of:
pip install --pre python-flint
pip install python-flint==0.7.0a4I would be interested to know what output you see but I hope it will be something like:
Error: Flint >= 3.0 is required.The fact that it can check the Flint version is because the build system has changed from setuptools to meson and meson can check the version and fail the build. Oh, actually no it won't because we're not checking it here: https://github.com/flintlib/python-flint/blob/162ded1afcc2c41c681283040272b029efb110c6/meson.build#L10 It should be something like:
flint_dep = dependency('flint', version: ['>=3.0', '<3.2']Probably 3.2 is already compatible (we have a CI check against Flint main branch). I'm not sure how to manage an upper cap on the version here. When 3.1 came out it was not compatible (prior versions of python-flint would have failed to build). I expect that the same would happen with 3.2 because it only takes one small change to break the build so realistically each new 3.x version of Flint probably requires a new release of python-flint.
Going forwards I would like to keep 3.0 as the minimum supported Flint version for as long as possible but there were big changes in 3.0 and it didn't make sense to try to support both Flint < 3.0 and Flint >= 3.0 at the same time.
I think that then is the actual problem although I may be wrong. You need Flint >= 3.0 to build python-flint since python-flint 0.5.0. The changelog in the README notes supported version changes.
Flint 3.0 was released about 18 months ago I think? So it's pretty new. You either need to build Flint from source or you can maybe get it in a distro binary.
The only distro version I know of that provides Flint 3.0 is Ubuntu 24.04 (released a few months ago). On that distro you can install Flint 3.0.1 with:
sudo apt-get install libflint-devThat is tested in CI although not on aarch64 (no CI runners available): https://github.com/flintlib/python-flint/blob/162ded1afcc2c41c681283040272b029efb110c6/.github/workflows/buildwheel.yml#L123-L139

Hello,
I hope this is the correct location to ask about such an issue. I have been working with
pip install --upgrade python-flint==0.3.0without problem, and recently tried to install the latest version viapip install python-flintafter uninstalling the above version. When doing so, I run into the following error message:I apologize if this is the wrong place to ask such a question, or if this is a personal issue rather than an issue with the code. Thank you for the help!
