Error installing pyarrow

[AndreTh]

Dear all,

I'm trying to install the package pyarrow, which is used for another package (streamlit) on the revpi.
It fails using "pip install pyarrow" as there is no pre-compiled wheel and the ressources of the revpi seem to be not sufficient for compiling it locally.
Instead I tried to cross-compile it under Windows with docker for the revpi but also there I face problems with cmake. Cmake fails with the error "Unknown system processor" although I have used the option "-DSYSTEM_PROCESSOR=armv7l".

Does anyone faced similar problems and managed to compile the package for the revpi?

Thanks for all hints and help.

Best regards,
André

Looks like they provide wheels for aarch64: https://pypi.org/project/pyarrow/#files

Any reason you use a 32-bit image? Starting with Bookworm there will be only 64-bit images, so maybe it is a good opportunety and then switch to the official pyarrow wheel ?
