[kif]

To summarize, you are trying to build from source pyFAI v 2023.09 with those dependencies:

• Python 3.12
• gcc14
• cython 3.0.10

Which version of numpy are you using ? numpy2 support has only been introduced in version 2024.05.

[opens21]

Yes, the dependencies are correct. I am using numpy2. Is there any workaround or fix?

[kif]

The are only 2 alternatives:

• Either one uses pyFAI v2023.09, as imposed by some extra software, together with numpy 1.26 and silx 2.0
• Or one uses pyFAI v2024.05 together with any version of numpy and silx 2.1.

I have no resources to backport fixes. So if you find new bug, they will only be fixed in the development branch.
