Feature request: run llvmlite on android

[LaRevoltage]

When running pip3 install numba I get:

I am using python 3.9.6 and I can't solve this

@MajorRaccoon thank you for asking about this. What version of Pip are you using? Which operating system is this on? And what kind of hardware/chipset are you running?

@MajorRaccoon is this on an Android phone using termux?

I spotted RuntimeError: Could not find a llvm-config binary. in the error. Looks like pip is trying to install llvmlite from source because no wheels are available for the platform.

Yes, I concur with that assessment. In such a case some kind of llvmdev must be obtained first (compile or download) and also functioning compilers will be needed for the target platform that will be able to handle both llvmlite and Numba.

Yes it is. pip 21.2.4

Interesting. Well, AFAICR you are the first person to report having tried this. I am not sure what to recommend other than: keep trying, keep asking specific questions and let us know if you make it! Good luck!

I have updated the title of the issue to reflect more closely on the ask.

Could we use the llvmlite wheel packages for android developed by chaquopy ? https://chaquo.com/pypi-7.0/

If there is a script and instructions on how to setup target hardware, this may very well be an option.

In short:

pkg install tur-repo
pkg install llvm-14
export LLVM_CONFIG=/data/data/com.termux/files/usr/opt/libllvm-14/bin/llvm-config
pip install llvmlite

Pasting it here, also as an aide-memoire, as I keep forgetting it when upgrading llvmlite...
